Hey @Andriana !
PM from the Office Scripts team here - happy to see you're trying out our feature :) We currently don't offer a VBA to macro converter, but one thing I've found useful is to try using the Action Recorder to record the steps I might take in my macro, then looking at and tweaking the resulting code in the code editor. Let me know if this helps, happy to investigate any issues you have with the conversion process.
Cheers,
Nancy
