I have been working with files and spreadsheets created or maintained by various software programs. Sometimes they do not convert to GS-Calc format easily. I have had success with these files by doing the following:
- Import them into Google Sheets
- Make some minor changes, if you like
- Download them as an OpenDocument .ods formatted file
- Open this file with GS-Calc
I’ve had decent success doing this and thought I’d share it with you.
