JSON Formatter & Validator
Pretty-print, validate, and minify JSON. Paste your JSON and get instant formatting with error highlighting.
Why JSON Needs Formatting
Minified JSON is compact for machines but hard for humans to read. A formatter adds indentation, validates the structure, and makes it easier to spot missing commas, wrong brackets, or unexpected values. This tool also provides a tree view when you need to inspect a large response quickly.
When You Will Use It
- Reading an API response from a browser console or log file
- Cleaning up a JSON snippet before sharing it in a ticket or documentation
- Validating JSON generated by another program or AI assistant
Can formatting change the data?
No. Formatting only changes whitespace and line breaks; the values and structure stay the same.
