Understanding the Conversion

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write, and easy for machines to parse and generate. It's based on a subset of JavaScript and is widely used for data exchange.

What is TOON Format?

TOON is a human-readable text format that represents structured data in a hierarchical manner. It's designed to be more visually intuitive than JSON while maintaining all the data relationships.

Conversion Process

Our converter parses your JSON structure, identifies all objects, arrays, and primitive values, then reconstructs them in TOON format with proper indentation and hierarchy preservation.
