User reviews
Wonderful add-on. Works perfectly.
I did however spend 10 minutes wondering what the hell was wrong with google sheets because my "$A$1" was being converted to "A0,96€".
Heavily recommend whitelisting google spreadsheets as soon as you install the extension. Or make it a default setting?
