Save and share MS Excel 2013 documents to your computer or OneDrive account. In Excel save as PDF also helps for Excel spreadsheets.
Excel automatically saves your workbooks to a temporary folder while you are working on them. If you forget to save your changes or if Excel crashes you can restore the file using AutoRecover.
By default, Excel autosaves every 10 minutes. If you are editing a workbook for less than 10 minutes, Excel may not create an autosaved version.
If you don't see the file you need, you can browse all autosaved files from Backstage view. Just select the File tab, click Manage Versions, then choose Recover Unsaved Workbooks.
