To use the text recovery tool, you do the following:
- Open Word
- Click File (top left)
- Click Open (top left)
- Click Browse (Other Locations)
Note: Don't open the file from the built in file explorer, click on Browse or OneDrive or another location so as to open the Open Window
In the Open Window, the file type field is above the Open button and the Cancel button. [ All Files (.) ]
- Click on the file type field to open the file type drop down menu.
- Select "Recover Text from Any File (.)"
- Open the damaged file (if you can)
- Delete the binary data at the start and end of the file before saving.
- Save the file.
This tool didn't work for me when I had trouble, which is why I devised the google drive/docs method.
Check the link below for other methods to fixing damaged word files. This list of methods is pretty comprehensive and includes the "Recover Text from Any File" method and the Save the document to other formats method, which is like the google drive/docs method.

YMMV and no method is guaranteed. Good luck.
