thanks, @Jonathan_S and @Phil
i hope to continue using the create feature in appsheet, it should be the best option.
I’m not stuck with this problem. But I think there is a bug here that should be addressed.
it feels best practice and i’ve been very happy to let appsheet create the xlsx attachment template in Drive, then edit in Google Sheets. No download/upload steps has to be better.
Further, unlike @ Srikanth_S my users can only open the xlsx attahment in Outlook, hence will always get the errors.
For this particular template, as you said, @Phil, i downloaded the raw appsheet-created xlsx attachment template, you do not say if you get the errors, i let Excel “fix” them saved that over the original and uploaded to Drive, this attachment does not give errors anymore.
But the root question is if no one else gets this error, while I and a few others do?
if so, there is a problem with appsheet creating some xlsx attachment templates.
Significantly, another appsheet created xlsx template never gave me the errors, here:
INVOICING REPORT BY JOB DOCKET_AttachmentTemplate_20200211_214016.xlsx
i think this needs to be fixed.
