Observed behavior

Frequently Asked Questions

Why does pressing Ctrl+V open a comment instead of pasting in Excel?

This happens when Excel's internal keyboard mappings become corrupted or conflict with third-party software. Reinstalling or repairing Microsoft Office usually resets these shortcuts to their default behavior.

Will my data be lost if I run the Office setup executable again?

No, running Officesetup.exe to repair or reinstall Microsoft Office will only replace and fix the application files. Your personal Excel files and spreadsheets will remain untouched.

How do I know if an Excel add-in is preventing me from typing?

Launch Excel in Safe Mode by holding the Ctrl key while clicking the Excel shortcut. If you can type and paste normally in Safe Mode, a third-party add-in is likely causing the problem.

Does Excel for the Web have the same input issue?

No, this specific input and shortcut issue is typically isolated to the desktop application. Excel for the Web runs within your internet browser and is not affected by local desktop software corruption.
