Hi benhaminHN,
Thank you for querying in this forum. We understand the inconvenience caused and apologize for it. And we will try our best to help you.
According to your description, it seems that your Excel will overwrite your formulas with the other formulas added to the other cells in the same column. And you have tried turning off "Extend data range formats and formulas".
If my understanding is right, we have tested it on our side, we created a simple Excel file and we typed different formulas in different cells under same column, and we cannot reproduce the same situation as yours. As shown below:
Given this situation, we’d give you some suggestions below and hope that will help you:
- We assume that you may use Autofill in Table formulas, to prevent this situation, we’d suggest you go to Excel > File > Options > Advanced > unselect Enable fill handle and cell drag-and-drop. Then you can also go to Excel > File > Options > Proofing > AutoCorrect Options > AutoFormat As You Type > unselect Fill formulas in tables to create calculated columns.
- If the suggestion above doesn’t work, you can open your Excel in safe mode to check if the same problem will occur. It will help in identifying an add-in or extension that may be causing a problem on startup. As steps shown below: Right-click the Start button (lower-left corner) in Windows, and click Run.> In the Run box, type one of the command: excel /safe
- We’d also suggest you go to Control Panel > Programs > Programs and Features > select Office> right-click and select Change > Online repair.
If all suggestions above don’t work, to better understand your situation, could you provide the information below?
- Could you please share a screenshot of your Product Information and version of your Office? You can go to Excel > File > Account and provide the full screenshot of Account
page. As shown below:
- May I know if all Excel files have the same problem? You can create a new Excel file to check if the same problem will occur.
Best Regards,
Sukie
