Default crawled file name extensions and parsed file types in SharePoint Server and SharePoint in Microsoft 365

APPLIES TO: 2013 2016 2019 Subscription Edition SharePoint in Microsoft 365

The crawl component of SharePoint Server can only crawl a file if the list on the Manage File Types page includes the file name extension. The content processing component can only parse the contents of a crawled file:

• When it has a format handler that can parse the file format.
• When it is enabled to use the format handler to parse files that have the file format and file name extension.

By default, SharePoint Server satisfies these requirements for many file types.

The following table shows all the file formats that SharePoint Server and SharePoint in Microsoft 365 have built-in format handlers for. The table shows one or several format ID and file name extensions for each file format. By default SharePoint Server and SharePoint in Microsoft 365 are enabled to parse files that have these file formats and file name extensions. For each file name extension the table also indicates whether the Manage File Types page by default includes the file name extension.
