Fix Excel Showing Missing Characters While Typing
Question details
The user experiences a typing delay where Excel drops characters or stays one keystroke behind until the Spacebar is pressed.

- Product
- Microsoft Excel
- Device & OS
- Windows PC
- Scenario
- Typing data directly into Excel spreadsheet cells.
- Observed behavior
- Excel displays one character behind while typing and shows only part of a word until the Spacebar is pressed. The issue is isolated to Excel, while Word and Outlook function normally.
Before making changes to system settings or the Windows registry, ensure you have saved all open Excel workbooks and closed the application to prevent data corruption.
Repair or Reset Microsoft Office Registry Keys
Corrupted background configurations in the Windows Registry can cause keystroke delays. Resetting the Excel registry key often resolves this issue completely.
The Windows Registry stores configuration data for Excel. If these keys become damaged, it can lead to erratic behavior like typing lag or missing characters. Renaming the key forces Excel to build a fresh, uncorrupted configuration upon its next launch.
Ensure Excel is completely closed. You can verify this by checking the Task Manager (Ctrl + Shift + Esc) to make sure no Excel background processes are running.
Press the Windows key + R to open the Run dialog box. Type 'regedit' and press Enter. Click 'Yes' if prompted by User Account Control.
In the Registry Editor, go to the following path: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Excel (Note: '16.0' corresponds to Office 2016, 2019, and Microsoft 365. If you use an older version, look for 15.0 or 14.0).
Right-click on the 'Excel' folder in the left pane and select 'Rename'. Change the name to 'Excel.old' and press Enter.
Close the Registry Editor and open Microsoft Excel. Test your typing to see if the missing characters issue is resolved.

Frequently Asked Questions
Why does Excel lag and miss characters when I type fast?
Typing lag in Excel is commonly caused by corrupted Windows registry keys, conflicts with outdated third-party add-ins, heavy background processing tasks, or graphics hardware acceleration issues.
Will repairing Microsoft Office delete my Excel files?
No. Running an Online Repair or Quick Repair only replaces and fixes the core application files of Microsoft Office. Your personal spreadsheets, data, and saved documents will remain completely untouched.
How do I permanently disable add-ins if Safe Mode fixes the typing issue?
To disable add-ins, open Excel normally and go to File > Options > Add-ins. At the bottom, select 'COM Add-ins' from the Manage drop-down menu and click 'Go'. Uncheck the boxes next to the add-ins you want to disable and click OK.
