[Free] Decode Json easily. JsonPath. Convert XML <> JSON

Hello friends:

With this extension we can get the elements of a Json easily by writing their path.

I have tested it with App Inventor and now with Kodular on an Android 9.

This extension is based on this library:

- Blocks.

  • Set a Json string and a path (see example). Get object or array.


  • Set a Json string, Show Json in pretty format.


  • Convert Json string to Xml string and Xml string to Json string.


- Example.

  • To carry out the tests we will use the author’s example.
