How to Edit Column Settings in SharePoint Online?
Existing columns of a list or library can be edited. Properties of the fields such as display name, type, or other related column settings can be updated through the column settings page. To change column settings in a list or library:
- Navigate to the SharePoint Online list or library where you want to edit a column.
- Go to the list or library settings page either from Ribbon or from the Site Settings menu >>Under the Columns section, Pick the column to update
- On the Edit Column page, You can make any necessary changes and click on the OK button to Save.
Please note, changing column type is limited within specific columns based on the current type of the column. Also, you may end up in data loss when switching between column type. E.g. When you switch from Multiple lines of text to Single line of text, Its limited to 255 characters.
