A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Try these recovery paths in order:
- In Excel, check File > Open > Recent. If the 2026 workbook appears there, open it and immediately save it to a known folder.
- Search the PC for Excel files. In Windows search or File Explorer, search for
*.xlsxand*.xls. If needed, sort by Date modified to find the most recent workbook. - Check Excel save locations: File > Options > Save. Verify the Default local file location and AutoRecover file location, then look in those folders.
- Try Excel’s unsaved recovery: File > Info > Manage Workbook > Recover Unsaved Workbooks. If the 2026 file was open and not saved properly, it may appear there.
- If the workbook was stored in OneDrive, check OneDrive and its Recycle Bin. If a file was previously saved there, version history may help recover an earlier copy.
- If the file was previously saved and then closed without saving changes, open the workbook and go to File > Info. Under Manage Workbook, look for a version labeled (when I closed without saving) and select Restore.
- If the workbook was overwritten or moved, in File Explorer right-click the file or its folder and check Restore previous versions.
Important details:
- AutoSave appears only for Microsoft 365 subscribers with the latest Excel for Microsoft 365. If AutoSave is not available, Excel may rely on AutoRecover instead.
- If the file path and name are longer than 218 characters, Excel can fail to save correctly with Filename is not valid.
- Excel saves by writing to a temporary file first, then replacing the original file. Antivirus or other software can interfere with that process.
If the workbook was never actually saved to disk or cloud, the best remaining option is Recover Unsaved Workbooks.
