JSON Formatter

Beautify or minify your JSON data.

About JSON Formatter

Raw JSON from APIs and log files is hard to read. Paste minified or messy JSON and beautify it with proper indentation, or minify compact payloads for production. Syntax issues are highlighted so you can fix broken responses before they break deployments. All formatting runs locally - ideal for API keys, customer records, and staging responses that must not leave your laptop. No file size paywall: use it for everyday debugging and documentation tasks. Developers pair this with our JSON to CSV tool when product teams need spreadsheet-friendly exports.
