JSON Designer4.4.3 - App Store

Start modeling - finally!
your JSON visualization & design tool

If you are new to the app: this app is out for a couple of years now and develpers greatly appreciate it. It is a design tool primarily, and has always been for free as my part of giving back to the developer community. I put some effort in a smoother design and made many adjustments from some valuable feedbacks. Code generators are a separate feature, which is connected to a payment, which is a practical way to show if you value the feature and the app itself. Depending on your feedback the app will be extended with further functionality. Enjoy JSON modeling!

tl;dr: Modeling is the core feature and for free as always, code generators have to be paid for (and save lots of time)
Despite the long existence of UML and best practices of software engineering you can't find any diagrams in the API documentations of Google, Facebook, Twitter and the likes.

So help yourself, stop deciphering unreadable example files and use this new simplified visual representation of JSON structures as object oriented models.

Methodology:
. Tree structures depict hierarchical structures of objects
. Multiplicity indicator of objects and attributes depict arrays

Examples and a tutorial are provided inside the App. Use JSON Designer to jump right into defining your API, without reading a single page of JSON documentation.

Features:
. Graphically model JMs, ie your JSON Models
. Export JM images to integrate in documentations
. Reverse-generate JMs from URLs or direct JSON input
. Browse hand-picked API examples
. NEW Generate Protocol Buffers .proto for gRPC
. Tutorial
. Open-in: exchange JSON files with other apps

Feedback is gratefully appreciated.

More that 65% of JSON Designer users say it's a must-have and are using it daily!

Optional code generators for backers (saving you lots of time): Obj-C, Swift, Java, Kotlin, JavaScript, Perl, Python, Ruby, PHP.
