JSON Formatter & Validator
Paste your JSON to beautify, minify or validate it. Everything runs in your browser.Frequently asked questions
Is the JSON formatter free?
Yes. It is completely free to use with no sign-up and no limits on how much JSON you can format, minify or validate.
Is my JSON sent to a server?
No. All parsing, formatting and validation happen locally in your browser, so your data never leaves your device. It is safe for API keys, order data and other sensitive payloads, and it works offline.
What is the difference between Format and Minify?
Format (beautify) adds line breaks and indentation so the JSON is easy to read and edit. Minify strips every optional space and newline to produce the smallest valid JSON, ideal for storing or sending over the network.
How does validation work?
The tool parses your input with the browser's native JSON engine. If anything is malformed, the status flips to Invalid JSON so you can spot a missing comma, bracket or quote and fix it before using the data.
Can I change the indentation or sort the keys?
Yes. Choose 2 spaces, 4 spaces or tab indentation, and turn on Sort keys to reorder every object alphabetically. Sorted, consistent output makes diffs and code reviews much cleaner.
Why would I format JSON for my online store?
Readable JSON makes it far easier to inspect API responses, debug webhooks, edit theme settings or check product and order exports. Minified JSON keeps those same files small in production.
