Good JSON editor but other features remain a mystery

This is great for editing JSON. You can edit anywhere inside the JSON. (Someone was saying otherwise.) There are also some fancy features for replacing multiple values at once. I have not used this feature but there is at least one video demonstrating it.
The only reason for 4 stars not 5 is that there are a lot of other great features it has that no one on my team can figure out how to use yet. We are too busy to spend hours trying to figure it out. And an email to support has so far gone unanswered. (About a week and a half now.) It is a shame because we could really use these feautures and several of us already own it.
They did put some time into trying to creating videos to show how to use it but some real documentation and more about setting it up for custom use is needed. (And you will want to slow down some of the videos! :o) )

Fantastic app for REST services developers

This app is worth so much more than its price. You have the option of setting up a single API for multiple environments with a base URL for each and common API endpoints, authentication schemes, json models, and queries for all of them. Once you've hit your API and received json responses, it will allow you to export objective-c models for the entire schema. It's incredible. I was able to map an entire API to an iPad app in a matter of a few days. I can't believe how helpful this app has been. Updated for new version.

Best JSON and API editor for OSX

I know others have reported crashing issues, but I’ve found the app to be quite stable, and the best json editor I’ve come across, but that’s not the best feature of this app, imo. I really appreciate the direct integration capabilities with api’s. I’ve found the support to be very responsive as well. For the price, it’s definitely the best value on the app store; I’ve tried other solutions, and found this better than the more expensive options.
