For now my workflow is:
- opening myfile.csv in numbers
- applying changes to myfile.numbers
- saving myfile.numbers
- export myfile.numbers to myfile.csv (overwrite old)
Rinse - repeat when new changes come in.
So I wondered - is there a way to force numbers to automatically export to .csv when I hit "save"? (i.e. combining steps 3&4?)
(no computer science background, just curious)
