How to format JSON online
Learn how to pretty-print messy JSON in your browser with Toolora’s free JSON Formatter.
Why format JSON?
Minified or one-line JSON is hard to read. Formatting adds indentation and line breaks so objects, arrays, and nested fields are easier to inspect while debugging APIs or config files.
Steps
1) Open the JSON Formatter tool. 2) Paste your JSON. 3) Click Run. 4) Copy the formatted result. If the JSON is invalid, fix the reported syntax issue and try again.
Tips
After formatting, use JSON Minifier when you need a compact payload again. Use JSON Validator if you only want to check validity without rewriting the text.
