Question details
The user is unable to type, copy, or paste data into new or existing Excel worksheets using the keyboard.

- Product
- Microsoft Excel 365
- Device & OS
- Windows 11
- Scenario
- Attempting to enter data or use keyboard shortcuts to paste content into spreadsheet cells.
- Observed behavior
- Excel ignores typed input, and keyboard shortcuts unexpectedly open a new comment instead of pasting data. Right-click paste and the web version of Excel continue to function normally.
Verify that your keyboard functions correctly in other applications, and ensure the 'Insert' key is not accidentally toggled on, as this can alter standard typing behavior.
Repair or Reinstall Microsoft Office
Running the Office setup file repairs corrupted application files that cause input failures and incorrect keyboard shortcut behaviors.
When Excel's core application files become corrupted, standard typing functions and shortcut mappings can break. In many cases, downloading and running the official Office setup executable resolves the problem without requiring you to manually uninstall the older version first.
Log in to your Microsoft account online and download the official Officesetup.exe installer package.
Double-click the Officesetup.exe file to run it. Allow the setup process to overwrite and repair your existing Microsoft Office installation.
Once the installation completes, restart your Windows computer. Launch Excel, open a blank workbook, and test typing or pasting data into the cells.

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.
