JSON Beautifier

Online JSON Formatter & Validator

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It's easy for humans to read and write, and easy for machines to parse and generate.

Features

• Beautify: Proper indentation (2 or 4 spaces) makes complex JSON structures readable.
• Minify: Remove all spaces and line breaks to compress the JSON for transmission.
• Validate: Instantly check if your JSON is valid and see exactly where the syntax error is.

Common JSON Errors

Unlike JavaScript objects, JSON keys must be double-quoted. Trailing commas are also not allowed in standard JSON. Our validator will catch these issues for you.
