Fix Excel Automatic Data Conversion Settings That Keep Resetting
Question details
The user is experiencing an issue where selections made under Excel Options for Automatic Data Conversion are automatically cleared and reset upon closing, even after completely reinstalling the application.
- Product
- Microsoft Excel
- Device & OS
- Windows
- Scenario
- Configuring Automatic Data Conversion options in Excel settings to manage how data is imported and formatted.
- Observed behavior
- The configured settings are not saved; they automatically clear and revert to default values every time Excel is restarted.
Verify your current Office version and installation method. If you plan to modify the Windows Registry during troubleshooting, ensure you export a backup of the registry first to prevent accidental system instability.
Run Excel in Safe Mode and Disable COM Add-ins
Starting Excel in Safe Mode disables external plugins. This helps determine if a third-party COM add-in is conflicting with your settings and causing them to reset.
Often, poorly coded or outdated add-ins interfere with Excel's ability to save configuration files correctly. Disabling them can restore normal behavior.
Press the Windows key + R on your keyboard simultaneously to open the Run window.
Type 'excel /safe' into the text box and press Enter. Excel will launch with a 'Safe Mode' indicator in the title bar.
Click on File in the top-left corner, select Options at the bottom, and then click on Add-ins in the left sidebar.
At the bottom of the window, ensure 'COM Add-ins' is selected in the Manage drop-down menu, then click the 'Go...' button.
Uncheck all the listed add-ins to disable them. Click OK, then close and restart Excel normally to see if your Automatic Data Conversion settings now save properly.
Recreate the Office Registry Key
Corrupted registry keys can block Excel from saving user preferences. Renaming the Office registry key forces the application to build a fresh, uncorrupted configuration.
Try WPS Office for a Stable and Seamless Spreadsheet Experience

Frequently Asked Questions
Why do my Excel settings keep resetting automatically?
Excel settings typically reset due to corrupted Windows registry keys, conflicting third-party COM add-ins, or corrupted installation files. In some cases, lacking proper administrative permissions to write changes to your user profile can also prevent settings from saving.
How do I access Automatic Data Conversion settings in Excel?
You can find these configuration options by navigating to File > Options > Data. Scroll down to the 'Automatic Data Conversion' section, where you can toggle rules for how Excel formats incoming data, such as removing leading zeros or converting long strings to scientific notation.
Is it safe to start Microsoft Excel in Safe Mode?
Yes, starting Excel in Safe Mode is completely safe and is a standard troubleshooting method. It simply launches the application with its default settings and temporarily bypasses custom add-ins and toolbars, helping you isolate the cause of persistent software glitches.
