Can we write Arcgis Pro file formats ( aprx) with the help of FME.

Hi there, I had a look through resources and I don’t believe this is supported directly. Arc Pro layer files (*.lyrx) are JSON format so in theory custom support could be written, a large undertaking

Perhaps the best course of action is to put this forward as an FME idea on the community.

there are other ideas for lyrx to vote up

Thank you botterill for sharing above information.
