Create Open in Excel experiences

Learn about creating Open in Office experiences for Excel and Word.

What are Open in Excel experiences?

Open in Excel experiences are:

  • Based on Entities and the OData services they create.
  • Dynamically generated or based on a pre-defined template.
  • Editable and refreshable via the Excel Data Connector App.

The following image shows the Excel Data Connector App inside the Journal Entry in Microsoft.


Where are the Open in Excel experiences?

Open in Excel experiences are usually found under in the Open in Excel section of the Open in Microsoft Office menu, but an explicit button can be added for these experiences.

What's the difference between Export to Excel and Open in Excel?

The Export to Excel and experiences are both found in the Open in Microsoft Office menu:

  • The Export to Excel options are static exports of grid data. Each one corresponds to a visible grid. All the grid data for the current filter is placed into a workbook.
  • The Open in Excel experiences utilize the Excel Data Connector App to facilitate refresh and publish.

The following image shows the Open in Microsoft Office menu on the Fleet Customers form with a template Open in Excel option, a generated Open in Excel option, and a static Export to Excel option.


When will an entity show as an Open in Excel option?

When an entity has the same root datasource (table) as a form, it will be added as an option in the Open in Excel section of the Open in Microsoft Office menu. This is referred to as a “generated” option.

What fields will be shown in the workbook?

The default fields that will be added into the workbook are the key and mandatory fields of the entity. If a different set of fields should be provided by default, then those fields can be added into the AutoReport field group on the entity. The following image show the Visual Studio view of the AutoReport field group for the FMCustomerEntity.


What fields will be shown when an entity is the target of a lookup?

When a relationship is defined between two entities, if the identifier for one entity is shown on the other then the fields that will be shown in that lookup are either the key fields, or the fields in the AutoLookup field group if it is not empty. Relationship lookups are not currently supported, but they will eventually be displayed in the app in a similar way to the enumeration lookups. Excel Data Connector App with an enumeration lookup is shown below.


What should be done to make an entity ready for use in Excel?

Define the AutoReport and AutoLookup field groups and test them using the Excel App design experience.

Why does an automatically added entity option have “(unfiltered)” after the entity name?

Currently no filter is added to these options, hence the term “(unfiltered)”. In the future, an attempt will be made to apply the filter from the form to these options. For example, if a list of Customers was filtered to just Customers in the state of California, then, in the future, the entity will be scanned for the state field and if it was found then a filter would be automatically added.

How can an entity be added as an Open in Excel option on a form that doesn’t share the same root datasource?

A generated Open in Excel option can be added on any form by implementing the ExportToExcelIGeneratedCustomExport interface. When adding a generated option programmatically, the set of fields can be explicitly specified.

What are the region-specific considerations for defining entities?

The Open in Excel generated experiences can be made region-specific by adding region-specific fields into the AutoLookup group. Those region-specific fields will then be included in the generated workbook.

How can I create a custom lookup for an entity field in Excel?

A custom lookup can be shown for an Entity field.

  • Name - The method needs to have a name that is “lookup_<fieldname>” e.g. a field “MyField” could have a lookup method “lookup_MyField”.
  • Attributes – Attributes need to be added to the method:
    • SysODataActionAttribute(str <name>, Boolean <isInstanceMethod>)
    • SysODataCollectionAttribute(str <name>, Types <type>, “Value”)
  • Return – The method should return a list of strings.


public class ExportToExcel_SimpleEntity extends common
    [SysODataActionAttribute("Lookup_StringLookupField", true),
    SysODataCollectionAttribute("return", Types::String, "Value")]
    public List lookup_StringLookupField()
        List lookupList = new List(Types::String);
        const int items = 5;

        for (int item = 0; item < items; item++)
            lookupList.addEnd(strfmt('%1 - %2 (%3)', this.StringField, this.IntField, item));

        return lookupList;

How does the app get injected into a workbook to start building a template?

The Excel Data Connector App is injected into a workbook when a generated Open in Excel experience is triggered or when a workbook is created using the Common > Common > Office integration > Excel workbook designer form.

  • The Create workbook button will add the selected entity and fields, a pointer to the server, and the app into a workbook.
  • The Create blank workbook button will simply add a pointer to the server and the app into a workbook.
  • The View related form will navigate to the form relating to the currently selected entity to more easily review the effect of data changes made in Excel.
  • The Get entity record count button will show the record count for the currently selected entity. Currently, the Excel Data Connector App cannot handle large (tall and wide) data sets. Any unfiltered entity with more than 10,000 records is at risk of crashing the app.

The following image shows the Excel workbook designer form.


After obtaining a workbook containing the Excel Data Connector App, additional datasources can be added via the Design button. Currently, datasources cannot be removed. The following image shows the Excel Data Connector App with the Design button highlighted.


When will a template show as an Open in Excel option?

When a template listed in the Common > Common > Office integration > Document templates form (DocuTemplate) has ShowInOpenInOfficeMenu set to Yes and has the same root datasource (table) as the current form, it will be added as an option in the Open in Excel section of the Open in Microsoft Office menu. The following image shows the Document templates form.


Will a filter be added to the template?

In the Document Templates form, the standard filter for “current record” can be turned on and off. If the filter is on, then when the template is invoked as an Open in Excel option and a filter for the current record will be added to the workbook. The filter will be the key fields and their values.

How can templates be defined in metadata and code and loaded automatically?

When adding a template into the Document Templates form, it is added for that instance and is referred to as a “user-defined” template. Templates can also be defined in metadata and code and loaded in an automatic way, thus making them “system-defined” templates. To create a system-defined template via metadata and code:

  • Define the template.
  • Create a new resource in a project.
  • Define a new class that extends the DocuTemplateRegistrationBase class and add an implementation of the registerTemplates method.

The LedgerJournalLineEntryTemplateRegistration and FMTemplateRegistrations classes are good examples of template registrations defined in code. And the LedgerJournalLineEntryTemplate and FMTemplateCustomersWithLocations resources are the corresponding templates stored in metadata as resources. When a template has a registration class, it will be loaded when the Reload system templates button is clicked in the Document Templates form.

How do templates get loaded into a fresh deployment?

To load system defined templates, click the Reload system templates button in the Common > Common > Office integration > Document templates form, as shown below.


In the near future we will do the equivalent of clicking that button during deployment.

How do I decide if I should create a template?

A template is an artifact that needs to be maintained and versioned. If you can avoid defining a template without sacrificing much from the user experience, then you probably should use a template. Create a template if:

  • You need additional content or formatting in the template.
  • You want to combine multiple entities/datasources in the same workbook.

Don’t create a template if:

  • You can just specify a set of fields to show in a table binding.

What are the region-specific considerations for templates?

When creating a template for an entity that has region-specific fields, you should leave those region-specific fields out of the template since otherwise all users will see the region-specific fields. Templates should cater to the majority of users by default and region-specific users can add those fields using the easy-to-use design experience of the Excel Data Connector App. The region-specific fields and columns can be added by users as needed and then that template can be either saved to local computer for reuse by a single user or uploaded via the Document Templates form for reuse by any user of that instance. A couple of other considerations:

  • If a region has a region-specific entity, then a region-specific template could be created.
  • If a region is important enough, then you could define a region-specific template as well as a region-generic template.

How do I add an explicit button for a template Open in Excel option?

An explicit button can be added for Open in Excel experiences. The label shown on the button should usually be “Open target in Excel” where target is the name of the target data like “lines” or “catalog”. The code behind such a button will:

  • Obtain the template to be used.
  • Add the desired filter.
  • Pass the template to the user.

An example of such code can be found on the LedgerJournalTable form (General ledger > Journals > General journal) in the Clicked method on the OpenLinesInExcel button.

    class OpenLinesInExcel
        /// <summary>
        /// Opens the current journal in Excel for line entry and editing
        /// </summary>
        public void clicked()

            const str templateName = resourceStr(LedgerJournalLineEntryTemplate);
            DocuTemplate template = DocuTemplate::findTemplate(OfficeAppApplicationType::Excel, templateName);

            // Ensure the template was present
            if (template && template.TemplateID == templateName)
                Map filtersToApply = new Map(Types::String, Types::String);

                // Create lines filter
                ExportToExcelFilterBuilder filterBuilder = new ExportToExcelFilterBuilder(tablestr(LedgerJournalLineEntity));
                str filterString = filterBuilder.areEqual(fieldstr(LedgerJournalLineEntity, JournalBatchNumber), LedgerJournalTable.JournalNum);
                filtersToApply.insert(tablestr(LedgerJournalLineEntity), filterString);

                // Create header filter
                filterBuilder = new ExportToExcelFilterBuilder(tablestr(LedgerJournalHeaderEntity));
                filterString = filterBuilder.areEqual(fieldstr(LedgerJournalHeaderEntity, JournalBatchNumber), LedgerJournalTable.JournalNum);
                filtersToApply.insert(tablestr(LedgerJournalHeaderEntity), filterString);

                // Generate the workbook using the template and filters
                DocuTemplateRender renderer = new DocuTemplateRender();
                str documentUrl = renderer.renderTemplateToStorage(template, filtersToApply);

                // Pass the workbook to the user
                if (documentUrl)
                    Browser b = new Browser();
                    b.navigate(documentUrl, false, false);
                    error(strFmt("@ApplicationFoundation:DocuTemplateGenerationFailed", templateName));
                warning(strFmt("@ApplicationFoundation:DocuTemplateNotFound", templateName));

To programmatically add generated and template Open in Excel options Open in Excel options can be programmatically added by implementing the ExportToExcelIGeneratedCustomExport and ExportToExcelITemplateCustomExport interfaces. This allows the addition of options to forms where the entity or template doesn’t have the same table as the root datasource. A good example of when you would use this capability is on forms without a datasource, potentially containing just a collection of form parts. The following example adds generated and template Open in Excel options programmatically to the FMRental form.

public class FMRental extends FormRun implements ExportToExcelIGeneratedCustomExport, ExportToExcelITemplateCustomExport
    public List getExportOptions()
        List exportOptions = new List(Types::Class);

        ExportToExcelExportOption exportOption = ExportToExcelExportOption::construct(ExportToExcelExportType::CustomGenerated, int2str(1));

        ExportToExcelExportOption exportOption2 = ExportToExcelExportOption::construct(ExportToExcelExportType::CustomTemplate, int2str(2));
        exportOption2.displayName("Analyze rentals");

        return exportOptions;

    public ExportToExcelDataEntityContext getDataEntityContext(ExportToExcelExportOption _exportOption)
        ExportToExcelDataEntityContext context = null;

        if ( == int2str(1))
            context = ExportToExcelDataEntityContext::construct(tablestr(FMRentalEntity), tablefieldgroupstr(FMRentalEntity, AutoReport));

        return context;

    public System.IO.Stream getTemplate(ExportToExcelExportOption _exportOption)
        System.IO.Stream stream = null;

        if ( == int2str(2))
            stream = Microsoft.Dynamics.Ax.Xpp.MetadataSupport::GetResourceContentStream(resourcestr(FMRentalEditableExportTemplate));

        return stream;

    public void updateTemplateSettings(ExportToExcelExportOption _exportOption, Microsoft.Dynamics.Platform.Integration.Office.ExportToExcelHelper.SettingsEditor _settingsEditor)

How do I add a filter for a programmatically-added template Open in Excel option?

A template Open in Excel option can be programmatically added by implementing the ExportToExcelITemplateCustomExport interface and providing a template in the getTemplate method. A filter for that option can be programmatically added by using the ExportToExcelFilterBuilder API in the updateTemplateSettings method.

public void updateTemplateSettings(ExportToExcelExportOption _exportOption, Microsoft.Dynamics.Platform.Integration.Office.ExportToExcelHelper.SettingsEditor _settingsEditor)


_settingsEditor.SetFilterExpression(tableStr(RetailTmpBulkProductAttributeValueEntity), element.getExportToExcelFilterExpression());

DictDataEntity dictDataEntity = new DictDataEntity(tableNum(RetailTmpBulkProductAttributeValueEntity));

_settingsEditor.SetFilterExpressionByPublicName(dictDataEntity.publicEntityName(), element.getExportToExcelFilterExpression());


After a filter has been added programmatically, the resulting filter can be viewed in the Excel Data Connector App using the Filter button. The following image shows the Excel Data Connector App with the Filter button highlighted.


The following image shows the Excel Data Connector App with the Filter dialog opened.


How do I enable relationship lookups in Excel?

To enable relationship lookups in the Excel Data Connector, you must ensure the following metadata is set.

  1. The Role and Related Data Entity Role defined on the relationship need to be unique among all relationships on both the source and target entity. This is particularly important for relationships involving entities with lots of relationships, such as DimensionCombinationEntity. If you're not seeing an expected lookup, try changing the role names to the following format:
  • Role: [this entity's public name] + [target entity's public name] + [target entity field] + "Source"
  • Related Data Entity Role: [this entity's public name] + [target entity's public name] + [target entity field] + "Target"
  1. The Cardinality and Related Data Entity Cardinality need to be set appropriately.
  2. At least one constraint must be added to the relationship. With the exception of dimension relationships, which are a special case, the properties constrained must both be public.

How can I enable users to create new header records as well as lines in a workbook?

To enable creation of header records and related lines, the header data source must be added as a set of "fields" and the lines data source must be added as a related table. This pattern can work well for document data entry scenarios such as Journal entry.

To design a workbook with header fields and a lines table that enables header creation:

  1. In the Excel Add-in, click Design to open the Designer and click Add fields to add a header data source.
  2. Select the desired header fields. Be sure to include all the key fields or the New button won't be enabled.
  3. For all of the string header value fields, manually apply "Text" format for that cell using Excel ribbon > Home tab > Number group > set "Number" in the format dropdown. If the Text format isn't manually set on a string field and it happens to get a string value with leading zeros like "00045", then Excel will automatically change it to "45" and an error will be shown like: "Unable to change the value of PurchaseOrderHeader's PurchaseOrderNumber field as it is a key field". The API doesn't allow for automatically applying the text formatting on individual cells (vs table columns) currently, but in the future we will hopefully eliminate the need for this workaround.
  4. In the Designer, on the header data source, click the Add related table button represented by a double plus icon.
  5. Select the desired line fields.

An example of a header data source with a related table data source:

  • PurchaseOrderHeader (Fields)
    • dataAreaId
    • PurchaseOrderNumber
    • PurchaseOrderName
    • OrderVendorAccountNumber
  • PurchaseOrderLine (Table - related)
    • LineNumber
    • ItemNumber
    • LineDescription
    • OrderedPurchaseQuantity
    • LineAmount

To use a header and lines workbook to create a new header and some lines:

  1. In the workbook, put focus in a cell with a header value
  2. In the Excel Add-in, click New
  3. Enter header values and lines as needed
  4. Click Publish


If you are not seeing an expected lookup, validate relationship metadata by checking the metadata feed available at [YourSiteURL]/data/$metadata. Search the $metadat feed for the public name of your entity to find its EntityType element, then make sure there is a child NavigationProperty element with a name equal to the Role value of the relationship. If the navigation property exists, it will be used by the Excel Data Connector to show a relationship lookup. Lookups are not shown under the following conditions:

  1. All of the entity's key fields are included as constraints in the relationship.
  2. The selected field is a key and the selected record is not new.
  3. The authenticated user does not have permission to access the entity targeted by the lookup.

How do dimensions work?

The easiest way to set up dimension metadata on data entities is to use the data entity creation wizard, which will automatically create the private relationships and public display value fields exactly as the dimensions framework needs them. If you want to customize your dimensions setup, see Dimensions Overview. Lookups, at RTW, are only generated automatically for non-Ledger dimensions. Custom dimensions are not supported for the initial release, but support will be added in a future update. If you want to enable lookups for Ledger dimensions (MainAccount, Department, CostCenter, etc.), see the link above for guidance on creating relationships on DimensionCombationEntity and DimensionSetEntity fields; once those relationships are present, relationship lookups will be displayed in the Excel Data Connector. The Excel Data Connector supports two types of dimension data entry: editing the display value directly or each attribute of the display value in a separate column. If both the display value column and the individual attribute columns are bound, they can both be edited and published separately; if both the display value and an individual attribute are edited in the same row, the individual attribute change overrides the display value change.

How do I create formula table columns?

If a formula is needed in a table, then add a formula column. When in the field selection page for a table binding, click the "Formula" button above the Selected fields list to add a new formula column. The label and value for the formula are entered in the fields immediately below the Selected fields list. After adding a new formula column, leave the value empty and click Update. Once the field has been added to the table, use standard Excel capabilities to create a formula. Then copy the formula and paste it into the formula column value field. When defining a formula, make sure there is more than one row in the table, otherwise the formula that Excel gives you may be for ALL rows instead of THAT row. To specify just the current row, the at symbol ("@") is needed. For example, sum of four columns for all rows "=SUM(Table1[[ColumnA]:[ColumnD]])" versus sum of four columns for the current row "=SUM(Table1[@[ColumnA]:[ColumnD]])".

Known issues

Refresh doesn’t automatically occur in old templates

The ability to control “refresh on open” was added as a setting. To opt-in to the default behavior, existing templates and workbooks need to have the Refresh on open check box selected in Options > Data Connector > Refresh Options.

Error finding entity

The reference to entities changed from using the Private Entity Name (DataEntity.Name) to Public Entity Name (DataEntity.PublicEntityName). If the public and private names for an entity were different and that entity was used in an Excel template or workbook, then this will cause the following error to be displayed in the Excel App: “Error Finding Entity. Details: Entity "<DataEntity.Name>" not found”.


To resolve this, change the binding information in the affected template so that it points to DataEntity.PublicEntityName instead of DataEntity.Name.

  1. For the DataEntity.Name that needs to be replaced, determine the DataEntity.PublicEntityName, for example replace FMCustomerEntity with FleetCustomer.
  2. Find the affected template.
  3. Change file extension on template from .xlsx to .zip. off101m
  4. The file to be changed will be one of the webextension*.xml files in the xlwebextensions directory, such as 2015-05-25-FleetCustomersWithLocations.zipxlwebextensionswebextension2.xml.
  5. Open the file to ensure that you have the correct location.
  6. Find the DataEntity.Name, such as FMCustomerEntity. off101n
  7. Extract the zip file. off101o
  8. Open the webextension xml file.
  9. Replace the DataEntity.Name with the corresponding DataEntity.PublicEntityName.
  10. Save the webextension xml file changes.
  11. Rename the old zip file e.g. add “.old” to the name.
  12. Create a new zip file of all the previously extracted content. This usually involves highlighting the content inside the archive/zip folder and creating a zipped folder using that content. off101p
  13. Verify that the zip file has the “_rels”, “docProps”, and “xl” folders in the root of the zip file.
  14. Rename the zip file as needed, for example back to
  15. Change the zip file extension back to xlsx.
  16. Re-publish the workbook xlsx file, if needed.
