To answer the original question (I knew I had covered it somewhere):

How do you join 2 texts and separate with a new line?

Upload data on Google Sheet and Download

Have a better, more rounded solution to handle inline (`one\ntwo\nthree) and user Enter pressed line returns, for both doGet(e) and doPost(e). It is necessary to convert both types of strings with line returns to lists (arrays) in AppInventor, and to then convert these lists back to strings with line returns in the google apps script. This is due to the way textboxes and text blocks handle typed in \n and non typed in \n - with one being treated as text, the other being treated as a non printin…

You can do it with google forms prefilled data upload, but you will still need a script to handle the data when it arrives at the sheet.
