I have a document library with more than 10K documents in SharePoint Online Environment. Each document is having unique document name Now I want to upload metadata of 5 columns in it for each document.
Any suggestion !
SharePoint cares deeply about the unique document names, but any programmatic updates would require you to also export the IDs so that you can use them for import.
Document metadata can be added very much like you would update a regular list.
Manual options: Open each document properties and add the data manually... just kidding.
