Hello! Does anyone know of an application *that runs on Mac* and would let us do the following? 1. Edit and validate JSON schemas 2. Generate test/"blank" records from an existing JSON schema 3. Edit and validate XML schemas 4. Nice to have but not necessary: convert from XML to JSON for schema & records We know of XMLSpy which does all the above, but unfortunately it only runs on PCs. Everything we're working with right now is Mac except for a loaner laptop we borrowed temporarily to run XMLSpy. We've been using XMLSpy to do conversion to JSON and generate records, which we've then been working with in oXygen on our Mac computers but for obvious reasons that's not a great long-term system. In theory we shouldn't need to convert the schema from XML to JSON again so number 4 above is not really necessary, but just putting it out there in case! We've been searching around online but not finding much, and before we take more extreme measures we thought we'd check here and see if anyone knew of an option we were missing. Thanks in advance!
