I'm new to Google sheets, and I've got this spreadsheet with some IMPORTRANGE functions in them, and they look like this:
=IMPORTRANGE($O$2; "Jan!B33")
That first value, $0$2, is supposedly the spreadsheet key, but I'm used to that spreadsheet key coming from the HTML, for example "1QCfFIx6evcghuH4k74_ksqx6P7sb5xzUpRaoQobV6MA", or something like that.
My question is, what is this dollar sign notation, and how do I use it? Is it even something from Google Sheets or is it something someone mistakenly copied from Excel or another program?
That's an absolute cell reference. (The sheet's key is expected to be read from cell O2
.)
This range syntax is supported by Excel and Google Sheets.
