Hi Amit,
Thanks for posting in the community. We are happy to help you.
According to your description, the "Edit in grid option" is missing when viewing the list in Microsoft Lists, but it appears on the SharePoint site. Please try the following suggestions, then check again.
- The situation may be caused by your current view. To verify it, please switch to another view (if you don't have another view, please create a new view as shown in the below screenshot), then check again.
- The situation may be caused by your browser. Please use another browser, like Edge, open the private window of the browser, go to Microsoft Lists, and check again.
If the above suggestions don't help, to troubleshoot the situation, I would like to collect more information.
- Does the situation happen to a specific list or also happen to other lists?
- Are your colleagues in the same situation when viewing this list via Microsoft Lists?
We look forward to your response. Thanks for your cooperation.
Sincerely,
George | Microsoft Community Moderator
