A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Same / similar thing just happened to me, but my Excel file is saved to Google Drive. Not sure if that is lunacy having MS files on Google Drive and expecting support in the event of crisis. Computer crashed and somehow self-saved another Excel file over the top of my business critical file. I've just spent the best part of 3 hours following every recommended step on this forum and googling like a maniac to try and retrieve an earlier version of said file, all to no avail. Then just as I was about to give up, I stumbled on something new which I've seen no mention of anywhere .... so if all else fails try this.
Using the search function in File Explorer, search for the name of your document (partial name will do) making sure to "Search Results in this PC" rather than selecting a specific folder or drive. When your file appears right click on it and select Show More Options, then Manage Versions. If you're as fortunate as I was, it will produce a long list of versions of the file (I got 100 versions going back around 12 months) - sort them by the Date Modified field and then find the one you want. Hey Presto !
