JSON Formatter & Validator

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. Well-formatted JSON is crucial for readability and debugging.

How to Use This Tool:

Paste any valid or minified JSON into the input box and click "Format JSON". The tool will instantly parse, validate, and prettify your data with standardized indentation (2 spaces). If there's an error in your JSON structure, the tool will notify you so you can fix it.

Because this tool runs entirely in your browser, your data is never sent to a server. This makes it a safe and private way to work with sensitive or confidential JSON.
