Fix Excel Letters C, H, and V Not Working When Typing
Question details
The user is unable to type the specific letters C, H, and V in Microsoft Excel, despite the keyboard functioning perfectly in other software.

- Product
- Microsoft Excel
- Device & OS
- Windows
- Scenario
- Typing text or entering data into spreadsheet cells.
- Observed behavior
- Pressing the C, H, and V keys yields no response in Excel, whether using a laptop keyboard or an external Bluetooth keyboard. These keys continue to work normally in other programs like Google Chrome.
Verify that your keyboard is working properly by typing the problematic letters in Notepad or a web browser. Save any unsaved work in your Excel workbook before attempting system or application restarts.
Trigger the Windows Clipboard History Shortcut
Activating the Windows clipboard history can reset background shortcut conflicts that prevent specific keys from registering in Excel.
In many cases, the Windows clipboard service or an underlying OS glitch intercepts specific keystrokes (like C and V, which are commonly used in copy/paste actions). Triggering the clipboard manager interface forces the system to release these trapped keys back to the active application.
On your keyboard, press the 'Windows' key and the 'V' key simultaneously to bring up the Clipboard History panel.
Click anywhere inside your Excel spreadsheet to close the clipboard menu, then attempt to type the letters C, H, and V into a cell.

Restart Excel and Close Conflicting Utilities
A simple application restart or disabling third-party clipboard managers can clear temporary software conflicts.
Open Excel in Safe Mode to Isolate Add-in Conflicts
Running Excel in Safe Mode helps determine if a third-party Excel Add-in is blocking your keystrokes.
Switch to WPS Office for a Bug-Free Spreadsheet Experience
If Microsoft Excel continues to block specific keystrokes or conflict with your system clipboard, consider using WPS Office. It provides a lightweight, highly compatible spreadsheet environment that avoids common macro and add-in glitches.
- 1. Download the Installer: Visit the official WPS Office website and download the free installer for your operating system.
- 2. Install WPS Office: Run the setup file and follow the quick on-screen prompts to install the suite.
- 3. Open Your Spreadsheets: Launch WPS Spreadsheets and open your existing Excel workbooks to resume typing without interruptions.

Frequently Asked Questions
Why do specific letters randomly stop working only in Excel?
This usually happens due to a shortcut conflict between Windows and Microsoft Excel. Background services, particularly the Windows clipboard or specific Excel Add-ins, can accidentally 'hijack' keystrokes like C and V, preventing them from registering as text in your cells.
Does this keyboard issue only happen with Bluetooth keyboards?
No. While it can occur with external Bluetooth keyboards, users frequently report the same issue using built-in laptop keyboards. The problem stems from software conflicts, not hardware defects.
What should I do if the Windows+V shortcut does not fix the problem?
If activating the clipboard history does not work, try saving your file and fully restarting your computer. You should also run Excel in Safe Mode (by typing 'excel /safe' in the Windows Run dialog) to check if a third-party add-in is causing the issue.
Can Excel macros disable certain keys?
Yes. If a custom macro was inadvertently assigned to a specific letter key without requiring a modifier (like Ctrl or Alt), pressing that key will trigger the macro instead of typing the letter. You can check this by reviewing your macro shortcuts in the Developer tab.
