Microsoft Lists/Sharepoint lists Copy paste not working in "Edit in grid"

Question

Microsoft Lists/Sharepoint lists Copy paste not working in "Edit in grid"

Mower, Sean 20

A Windows update a few weeks ago caused several issues across our workstations. While IT resolved the primary problems, we've continued to experience a significant issue with Microsoft Lists and SharePoint Lists.

We use a Microsoft Lists-based CSV generator for our LMS that requires frequent data entry. Since the update, copy-and-paste functionality in Edit in Grid View has become extremely unreliable. Pasting names, email addresses, or other data only works intermittently, and values often disappear when moving to another field.

We've verified that copy-and-paste works normally in all other applications, cleared clipboard history, and even created new lists, but the issue persists across all Lists. This has effectively broken a critical tool that we use daily to onboard multiple users.

Please advise if this is a known issue or if there is an update or workaround available. At its current state, Microsoft Lists is extremely difficult to use for bulk data entry.

Exact same issue! Copying 75 rows fromn Excel into existing SP in Gride Edit mode. After existing rows I get spinning wheels and the Edit pencil symbol in the leftmost margin. The entire List becomes unsavable, meaning abort by having to delete the entire List with CTRL-A, Delete via dustbin symbol button (keyboard delete doesn't even work!)
According to community sources, this mess has been occuring since 2022, at least, when there was a swap to JS!
About time to get the thing fixed, I would imagine?! Using Copilot to save time (haha!) finding a fix and tried everything it suggested, for an entire day yesterday, such as rechecking all column validations, checking all URLs, checking for hidden codes in source Excel data, etc. Am going to have to resort to manual pasting if permitted, finally, this morning, as even Ai gave up and suddenly fessed up - claiming this has been a known issue for MS since 2022! https://techcommunity.microsoft.com/discussions/sharepoint_general/issues-saving-to-sharepoint-lists-in-grid-view/3612816

Yeah I am currently going through the troubleshooting steps with microsoft support. have replicated on my personal computer and 3 other computers. Doesn't matter if I am on the app or browser, edge or chrome.

Sean, hi! I got some joy this morning by clearing Edge's browsing history and restarting. I then pasted rows in small batches to catch anything dodgy, but all rows pasted fine this time! (MS please note, as a UX thing, I had no confidence in reattempting the one-fell-swoop pasting of all rows!)

I wish you well with your own issue!

Hi @Mower, Sean,

Thank you for providing these details. Based on the troubleshooting you've already completed and the fact that the issue appears to affect multiple Microsoft Lists and SharePoint Lists after a Windows update, this may require deeper investigation by Microsoft.

To resolve this issue, Microsoft's support team will need to be engaged. A technical support engineer can conduct a remote session to investigate the situation, verify backend configurations, and run any required synchronization tools. Since this case will likely involve collecting and analyzing logs, I recommend raising a support ticket to ensure a smoother and more efficient resolution process.

The Global Administrator for your Microsoft 365 tenant should create a service request with Microsoft Support to obtain advanced technical assistance and diagnostics. For detailed instructions on how to contact support, please refer to:

Get support - Microsoft 365 admin

If you're unsure who the Global Administrator is within your organization, you can find guidance here:

How do I find my Microsoft 365 admin? - Microsoft Support

I would also like to clarify that this is a user-to-user support forum, and I am not a Microsoft support engineer. Forum participants do not have access to backend systems and cannot directly investigate service-side issues, perform escalations, or review diagnostic logs. I can only provide guidance and best-practice recommendations based on the information available.

I hope this information helps, and please let us know if there are any updates from Microsoft Support after the investigation.
