Microsoft Excel 365 HUGE Memory Leak (50 GB RAM)
I have experienced the same problem. Really frustrating. Have to close all my open Excel workbooks and then reopen - luckily it can be saved before closing. At least it has never crashed my computer.
Mine does it when changing sheets (mostly when doing it quickly I think) and sometimes also when going to 'the edge' of the sheet, either far right or to the bottom. Sometimes I end there by mistake when getting to eager on the CTRL+Arrows.
I've also tried much of the standard procedure found around with no luck.
My setup is a Lenovo Legion laptop, i7 8750H, 32GB RAM, nVidia Geforce RTX 2080 and Eizo 4K screen and Win11
JosvaBS I've found a work around. Today I had a sheet with a plot causing the memory leak every time the plot appeared or reapperead when navigating in the sheet.
Since many seems to have 4k screens I tried setting the resolution to full HD (1920x1080) and with this resolution the sheet worked fine! Setting the resolution back to 4k caused the leak to happen again.
It is quite a bad workaround having to look at full hd on a 4k screen..
good idea for a temporary workaround.
hope next release will repair this issue.

- On my computer, the problem has returned. I noticed slower scrolling/refreshing in Excel. This time it was easy because I knew what I was installing recently (Windows Update + latest nVidia Studio driver).
Fix:
1) Delete HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office
= placebo effect, maybe 5% better, you may skip this
2) Reinstall nvidia latest "Game Ready" driver with "Perform a clean installation" selected
= it helped for me

TO ALL READING:
I can reproduce this nasty Excel memory leak on my machine in a matter of a few minutes if anyone at Microsoft is willing to take a serious look at this. Always happens when manually clicking between several tabs in virtually any worksheet I have open, large or small, including using the Ctrl + PgUp and Ctrl + PgDn shortcut keys. This has been going on consistently for a few months now and Excel was working perfectly fine before whatever update from Microsoft took place. It has gotten to the point where I simply cannot get my accounting work done. Other suggestions in the other posts did not work. I will try the online (web-based) version next to see if there is any difference. Kindly fix this terrible memory leak, Microsoft.
- Mine has been ok since the last uninstall/reinstall with SaRA when adding the registry clean as suggested by tomoam2. I'm hoping that will last but I don't have much faith given past experience with the issue. Mine could be easily triggered by switching sheets or keyboard shortcuts to move within a sheet. It occurred on all sorts of workbooks with different degrees of complexity.
