JSON Formatter & Validator

JSON Formatter, Validator & Beautifier

Working with minified API responses or messy configuration files can be a nightmare. Our free JSON formatter instantly beautifies your unreadable JSON strings into cleanly indented, easy-to-read code. It also serves as a strict JSON validator, instantly catching missing commas or unquoted keys.

Why use our JSON tool?

Because it respects your privacy. Many online JSON formatters send your payload to a remote server to be processed. If you are formatting JSON that contains PII (Personally Identifiable Information) or proprietary company data, that is a massive security risk. Our tool executes 100% locally in your browser.

Features

• Instant Validation: Real-time syntax checking alerts you immediately if your JSON is malformed.
• 1-Click Copy: No need to drag and highlight. Grab your beautified code with one button.
• Zero Server Logs: What happens on your machine stays on your machine.
