I know ARRAYFORMULA is out of favor at the moment, and that’s great. Because it seems to me there’s a fundamental problem with it: namely, the ARRAYFORMULA itself exists in a row of your data. If that row gets deleted, your ARRAYFORMULA is gone. (I’ve tried it.) Have I missed something? Because, if…

I laughed out loud at the “Header” thing because I was trying to figure out a trick like that earlier. Nice one! In the second example, wouldn’t you end up with a blank row in your data? For some apps not a problem, I image. But still. Thanks!

Yeah, I agree with that. But it’s clear from the online discussions that people still use it. I’ve been staying away from it myself, although once in a while I’m certainly tempted. :smiling_imp:

[image] escott: Because, if not, every ARRAYFORMULA is a bug waiting to happen. (Yes, you can work around this in various ugly ways, that IMHO are also bugs waiting to happen.) Absolutely agree with that, and have been bitten by it in the past. I have older projects that still have the odd a…

The doc needs to catch up with current practice. ARRAYFORMULA is still there, with no warning about this issue or, IIRC, any other.

yeah, for sure. That whole section on Spreadsheet Tips is really outdated. There is a big effort going on at the moment to update the Glide Docs, but I don’t believe this section has been touched yet.
