Detailed properties in the Office 365 audit log

When you export the results of an audit log search from the Security & Compliance Center, you have the option to download all the results that meet your search criteria. You do this by selecting Export results > Download all results on the Audit log search page. For more information, see Search the audit log in the Office 365.

When your export all results for an audit log search, the raw data from the Office 365 unified audit log is copied to a comma-separated value (CSV) file that is downloaded to your local computer. This file contains additional information from each audit record in a column named AuditData. This column contains a multi-value property for multiple properties from the audit log record. Each of the property: value pairs in this multi-value property are separated by a comma.

The following table describes the properties that are included (depending on the Office 365 service in which an event occurs) in the multi-property AuditData column. The Office 365 service that has this property column indicates the service and type of activity (user or admin) that includes the property. For more detailed information about these properties or about properties that may not be listed in this topic, see Office 365 Management Activity API Schema.

Tip

You can use the JSON transform feature in Power Query in Excel to split the AuditData column into multiple columns so that each property has its own column. This lets you sort and filter on one or more of these properties. To learn how to do this, see Export, configure, and view audit log records.
