hi Craig,
“cURL.exe” comes with Windows 10 by default. If you’re using an older version of Windows you might have to install it .
You can get the windows version from here (you will have to UNZIP it before it can be used).
I found this link via this article on StackOverflow
Hopefully, all you need to do is put “curl.exe” in the same folder as the spreadsheet, that should fix it. Click “check connection” in the spreadsheet when you’ve got curl, let me know how you get on
I’ll update our download page with this link to CURL as well, in case others run into the same problem.
All the best,
Nick
