I am struggling to write a Google App Script that allows me to combine cell values across rows in Google Sheets into text that appears in a separate Google Doc (and that ideally allows the formatting to be kept). Example of what I am after :

I have done a mail merge before, but I don't want separate documents for each row. I tried to edit an old script and use that, but it just created >100 new documents in my Google Drive, so something is not going right. I just want a paragraph break to separate each row.
Ideally, I'd love a version of the script that just prints to the same document every time it is run.
Any ideas? Would love any examples, if you have ideas! Really appreciated.
