    Hi, I'm John! I will help you with this.

    To help narrow down the issue:

    1. Do you see any error message when you try to save the file?
    2. Where is the file currently stored (for example: local drive, USB, OneDrive, network folder)?
    3. Does this happen with all Excel files, or only with this specific one?
    4. 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.

    If Excel 2021 is not saving changes when you edit your spreadsheet, there are several potential reasons for this issue:

    1. Disk Space: Ensure that the disk where you are trying to save the file has sufficient free space. If the disk is full, you will receive a "Disk is Full" error message.
    2. Antivirus Software: Sometimes, antivirus software can interfere with the saving process. If you receive an error when trying to save an existing workbook, try temporarily disabling your antivirus software to see if that resolves the issue.
    3. File Sharing: If multiple users are working on the same shared workbook, conflicts can arise if two users attempt to save changes simultaneously.
    4. File Naming: Ensure that the file path, including the file name, does not exceed 218 characters, as this can lead to a "Filename is not valid" error.
    5. Permissions: Check that you have the necessary permissions (read and write) for the folder where you are trying to save the file. If you only have read permissions, you will not be able to save changes.
    6. Third-Party Add-Ins: If you are running any third-party add-ins, they may be causing issues with the saving process. Try starting Excel in Safe Mode to see if the problem persists.

    If the problem continues after checking these factors, consider saving the file to a different location or contacting Microsoft Support for further assistance.
