This topic explains how to work around the Excel 2003 row limitation when you export paginated reports to Excel. The workaround is for a report that contains only a table.
The Microsoft Excel 2003 (.xls) rendering extension is deprecated. For more information, see Deprecated Features in SQL Server Reporting Services in SQL Server 2016.
Excel 2003 supports a maximum of 65,536 rows per worksheet. You can work around this limitation by forcing an explicit page break after a certain number of rows. The Excel renderer creates a new worksheet for each explicit page break.
To create an explicit page break
Open the report in SQL Server Data Tools - Business Intelligence or the Reporting Services web portal.
Right click the Data row in the table, and then click Add Group > Parent Group to add an outer table group.
Enter the following formula in the Group by expression box, and then click OK to add the parent group.
The formula assigns a number to each set of 65000 rows in the dataset. When a page break is defined for the group, the expression results in a page break every 65000 rows.
Adding the outer table group adds a group column to the report.
Delete the group column by right-clicking on the column header, clicking Delete Columns, selecting Delete columns only, and then click OK.
Right click Group 1 in the Row Groups section, and then click Group Properties.
On the Sorting page of the Group Properties dialog box, select the default sorting option and click Delete.
On the Page Breaks page, click Between each instance of a group and then click OK.
Save the report. When you export it to Excel, it exports to multiple worksheets and each worksheet contains a maximum of 65000 rows.
