Does anyone know how to import XML into Balsamiq from http://webdemo.balsamiq.com/
I've have some mockup which I did last year, and I remember all the import and export were in XML format. Now they change to JSON format, I'm wondering how could I get back my old mockup source.
I found the solution.
Rename it to bmml extension, then Import BMML Mockups. Once done, export it into JSON format.
