JSON Formatter & Validator
Paste your JSON data below to format, validate, minify, or convert it to CSV.
Why Use a JSON Formatter?
This free json formatter & validator runs entirely in your browser; your data is never sent to any server. However, raw JSON is often minified (compressed onto a single line) to save bandwidth, making it completely unreadable for humans. Our JSON Formatter instantly "prettifies" this data by adding proper indentation and line breaks, making it easy to read and debug.
Features of this tool:
- Validation: Instantly catches syntax errors (like missing commas or unquoted keys) and tells you exactly what went wrong.
- Minification: Removes all unnecessary whitespace from your JSON to prepare it for production use.
- CSV Export: Automatically flattens arrays of JSON objects into a comma-separated values (CSV) format, perfect for importing into Excel or Google Sheets.
