Excel file crashes after Big Sur updates.

In my previous case with Excel2016 (16.16 - now MS stopped to update) crashed at Big Sur, Excel spreadsheet file was not corrupt and Windows Excel opened the file without any issue. Upgrading to Excel2019 (16.44, 16.45) resulted in ok with Big Sur now.

I've been asking for the help from 7 apple chat advisors.

This is a workable. follow the steps below :

1) visit the icould.com , then click the iCloud Drive and upload one of the problem files .

2) then try to download it back to your Mac .

They recommend doing the same process on the documents so that they can be repaired and functioning again.

They also said that the files may have been damaged when upgrading.

wish it help !

In my case, the trigger of the excel crash was OS upgrade to Big Sur, however crash seems to happen in Mac Excel module during displaying the large spreadsheet. For me, both 2 actions worked: 1. Use Excel in Windows machine, 2. Update Mac Office to Office 2019. Hope this may be useful.

I hate to say this, but... I resolved my issues by upgrading to Office 2019 for Mac. Yes... Ouch!

Sorry to hear that. No issues for me with Big Sur 11.1 and Excel 16.45, part of MS 365 subscription.

One solution is to uninstall the application and reinstall it.

Take a look at some suggestions on Microsoft community forum here: this is searching on the term Excel + Big Sur

My Mac is up to date and with Big Sur. And the problems began after my last renewal of Office, which I assume is Office 2019.

Opening Excel, it would open jpg files and pdf files and everything except excel file - and they'd all be goobly gook. Then finally one would be an excel file that said it had been recovered. Then it might or might not work.

I did the upload/download to iCloud as suggested by someone earlier and the files are fine. Tried opening Excel without using that file and it's back to messed up - loading excel start up files.

Only thing that has worked for me is what someone earlier suggested: upload the file to iCloud, then download the file back to your laptop. It worked for me once or twice then you have to do it again. It is a pain!!!!

With Big Sur 11.1, crash happened in Excel (Office 2016 (16.16)) and Excel (Office 2019 (16.44)) works ok. Thanks for the information.

Try the latest LibreOffice.

If free spreadsheet application works, that is helpful. Note that Microsoft stopped to update Mac Office2016 last October, so no maintenance is planned for that level.

I’m using Home & Business; not Student/Home or Office Pro, but maybe the US packages are different? Have you tried opening the file is Numbers?

I am also having issues with Excel post Big Sur update. Same issue with .xls files crashing. Also with any files linked to other files crashing. Also having an issue with a large workbook and can't figure out what is causing that issue. I have even copied all of the data over to a new file and reentered all of the formulas, and that hasn't solved the crash issue. It's one I use regularly, so this is frustrating.

I'm using Office 365, so as a subscription software, it should remain up to date. Having the issue, nonetheless, so I don't think this is a bug related to whether a particular version of Excel is still supported or not.

Someone earlier said to upload to iCloud.com then download back to your computer and that worked for me - opening an excel file once or twice, then not anymore. So beyond that, who knows?!? Sorry.

I've just begun experiencing Excel Crashes on my 2015 27" iMac running Big Sur. Every time I go to set accounting format it crashes. A pretty essential function. Until recently I had enjoyed exceptional reliability running some extremely large spreadsheets. I'm also experiencing more general odd issues such as with mouse reactions! I haven't even begun to look for issues in Word etc!
