JSON Formatter

How to use JSON Formatter

Paste your JSON in the left panel and choose an action:

• Format — indents the JSON with the chosen indent size (2, 4 spaces...)
• Minify — compresses the JSON to a single line
• Sort keys — alphabetizes all object properties
• To TypeScript — generates TypeScript interface types from the structure
• Tree view — explore the JSON by expanding and collapsing nodes interactively
• Download — saves the result as a .json file

The validator shows in real time whether the JSON is valid or contains syntax errors.
