How JSON Formatting Works
JSON (JavaScript Object Notation) is a lightweight data-interchange format. This tool parses your JSON string and re-serializes it with proper indentation and formatting for readability.
- Format — Adds indentation and newlines for readability
- Minify — Removes all whitespace to reduce file size
- Validate — Checks if the JSON syntax is valid
All processing happens 100% in your browser. Your JSON data is never sent to any server.
