A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi, I'm John! I will help you with this.
To help narrow down the issue:
- Do you see any error message when you try to save the file?
- Where is the file currently stored (for example: local drive, USB, OneDrive, network folder)?
- Does this happen with all Excel files, or only with this specific one?
- Are you clicking Save, using Ctrl + S, or relying on AutoSave?
In the meantime, if you haven’t already:
- Open Excel and click File > Save As, then save the file to a different location (like your Desktop) and see if the changes are kept.
- Make sure the file is not marked as Read-only (right-click the file > Properties > uncheck Read-only if enabled).
- Try creating a new blank workbook, add some data, save it, and see if it works normally.
If the issue persists, please provide more details by answering my questions.
