Thanks for the suggestion and for the support of this feature. If you meant to vote for the Data Form, which is different than VBA UserForms, please change your vote to that suggestion instead. From reading the comments on this one, it seems that some clarification was needed.
I updated the title and description for this one and we’ll continue to monitor for comments and votes.

In response to Crigou - yes, Libreoffice does implement equivalent UserForms in its macro language. I have converted all my applications and abandoned Excel for Mac. You can use Python and other languages as well as Basic too.
I gave up and converted all my macro-enabled spreadsheets to LibreOffice. A bit of work to learn the new interface, but it all works, including the equivalent of Userforms, and its all cross-platform - Windows, Mac and Linux. And its free!
