What does JSON Formatter do?
It cleans up and checks JSON data — formatting messy text into readable indented structure, minifying it back down, validating it, and letting you explore it as a tree.
Common uses
- Readable formatting of minified API responses or config files
- Minifying JSON to save space for storage or transfer
- Validating JSON before it's used in code
Key features
- Format — prettify messy JSON with indentation
- Minify — compress JSON to a single line
- Validate — catch syntax errors
- Tree view — browse nested data visually
How it works
You paste JSON text or upload a `.json` file (up to 10 MB), then choose format, minify, validate, or tree view. Everything runs locally in your browser.
Tips
- Format first when debugging — indentation makes mistakes obvious
- Validate before pasting JSON into code to catch errors early
- Use minify only when size matters, not for daily readability
Verdict
JSON Formatter handles formatting, minifying, validation, and exploration. Open JSON and tidy your data — free and private.
