Fix Excel Opening Blank Documents or Forcing Files to Save as ODS
Question details
The user experiences an issue where a spreadsheet opens as a blank document unless it is saved in the ODS format and reopened, often resulting in a larger file size.

- Product
- Microsoft Excel / Third-party Editors
- Device & OS
- not provided
- Scenario
- Opening an existing XLSX spreadsheet or attempting to save files without losing data visibility.
- Observed behavior
- The file displays a blank screen upon opening. It only shows content if forced into an ODS format, which is caused by third-party editing software interfering with Microsoft Excel.
Verify whether the application opening your file is genuinely Microsoft Excel or a third-party program by checking the application's splash screen or 'About' section, as conflicting software associations are the most common cause.
Restore Default File Associations for Excel
Use this solution if your XLSX files are being hijacked and opened by an incompatible third-party spreadsheet editor.
When third-party software is installed, it can alter your default file associations, causing files meant for Microsoft Excel to open in another program. This often leads to compatibility issues like blank screens and forced ODS conversions.
Open File Explorer and navigate to the folder containing the problematic Excel file.
Right-click on the spreadsheet file, hover over 'Open with' in the context menu, and select 'Choose another app'.
Click on 'Excel' from the list of applications. If it doesn't appear, click 'More apps' to find it.
Check the box at the bottom that says 'Always use this app to open .xlsx files', then click 'OK' to apply the changes.

Repair or Reinstall Microsoft 365
Use this method if the default associations are correct but the native Excel application still fails to load the spreadsheet properly.
Open and Edit XLSX Files Seamlessly with WPS Office
If third-party software conflicts or Microsoft Excel errors are preventing you from viewing your data, switch to WPS Office. It handles all standard spreadsheet formats with ease, eliminating blank screen errors and avoiding forced ODS conversions.
- 1. Download WPS Office: Visit the official WPS website and download the free WPS Office installer.
- 2. Install the software: Run the setup file and follow the on-screen instructions to complete the installation.
- 3. Open your files instantly: Right-click your blank or problematic XLSX file, choose 'Open with', and select WPS Spreadsheets to view and edit your data flawlessly.

Frequently Asked Questions
Why does my Excel file open as a completely blank screen?
This can happen if file associations are incorrectly mapped to an incompatible third-party program, or if the 'Ignore other applications that use Dynamic Data Exchange (DDE)' setting is enabled in Excel's Advanced options.
What is an ODS file format?
ODS stands for OpenDocument Spreadsheet. It is an open-source file format used by various alternative spreadsheet applications. While useful, converting complex XLSX files to ODS can sometimes result in larger file sizes and lost formatting.
How do I stop third-party software from taking over my Excel files?
You can prevent this by right-clicking your spreadsheet, selecting 'Open with', choosing 'Choose another app', selecting Microsoft Excel (or WPS Office), and checking the 'Always use this app' box.
Can I recover data from the blank document?
Usually, the data is not lost; it is simply not rendering correctly in the program you are using. Opening the same file with its native application (like Microsoft Excel or WPS Spreadsheets) should display the data perfectly.
