Will SoluCGI work on MacOS or Office Online
Sorry. SoluCGI is for Windows / desktop Excel only.
Can I prepare playlists without the Add-In
Absolutely. SoluCGI has been used like this when musicians prepare lyrics for sing-along broadcasts. SoluCGI has also been used in a workflow where producer prepares content in cloud using google docs and operators just download the spreadsheet and run the graphics.
