Save a separate copy before editing the example. Use File → Save As or Save a Copy, depending on your version, and keep the .xlsx format to preserve worksheets, formulas, and formatting.
In Microsoft 365, AutoSave is normally enabled for files stored in OneDrive or SharePoint Online. Local files do not necessarily have AutoSave. Check the file location and save status rather than assuming changes are saved.
CSV stores a single sheet’s plain-text data and does not retain the complete workbook. Use CSV only when that export is specifically needed.
