I have an App which creates a series of .xlsx file for use in a mail merge extension in Sheets (YAMM). All have identical file schemas. They have to be saved as Sheets files before use but this is no problem
After a mail merge I want to get the results back into the App. I can choose a file using a view of the folders file collection. If I click on a file it is opened in Sheets but what I really want to do is to either use the file in the App or import it via a .csv.
Is there a way to either:
*. Open the file in the app, Or
- initiate an export of the file to a csv from within the app
i hope that makes sense,
