Add this app to your lists
Visualize, edit and format JSON data right on your Android device.
**If you have any suggestions, please e-mail us!**

Use copy/pasting, open it from sd card or load from an URL to get the JSON into the app, then you can use the auto-format function or remove whitespaces. At any time you can switch to tree-view to see the structure of your data. Also you can now view JSON files sent as e-mail attachments.

This app is for you if you are a developer, if you need to test a web service from time to time, or are just interested in JSON data format.

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is derived from the JavaScript scripting language for representing simple data structures and associative arrays, called objects.

    This program is tiny but is cursed with a splash screen, inept transitions, too many buttons, and crashed while attempting to open the file picker.

    Both editing Jason and viewing don't feel natural. For editing it should use a custom keyboard. For viewing it should have a better ui.
