Can I display a document library from another site collection as a Webpart in Sharepoint Online

Question

How could I display a Document Library from another Site Collection, in Sharepoint Online.

Could I create a Custom Web part and connect to the Sharepoint API?

Answer 1

If you only need to display files from another site (not expose them for editing), consider using the "Highlighted Content" web part on a modern page.

It allows you to pick a site to pull content from, then filter by content type, file type, and managed properties. You can use the "path" managed property to only get documents from a specific library (Path Begins with {library url}).

You will find that it is more limited than a list/library view web part in that you cannot specify which fields to display and your sort options are limited to "Most recent," "Most viewed," "Trending," and ascending or descending by a Managed property. However, it's good for quickly exposing files from another site, assuming the current user has access to view them.

Answer 2

Create a page with document library on source site and refer/add that page as page viewer webpart on destination part.

Answer 3

The embed web part can display a Document from another Site Collection. Just copy and paste the library address.
