Converter tool
JSON Formatter & Validator
Beautify, minify, validate, sort, copy, upload, and download JSON directly in your browser.
Your JSON is processed locally in your browser.
How the JSON Formatter works
Paste JSON into the input field or upload a JSON file. Choose your indentation style, optionally sort object keys, and then format, minify, or validate the data.
Formatting adds indentation and line breaks to make nested data easier to read. Minifying removes unnecessary whitespace to produce a compact version suitable for transport or storage.
When JSON is invalid, the tool displays the parser message and, when available, calculates the approximate line and column where the problem occurred.
Common JSON uses
API responses
Beautify compact API output so objects, arrays, and nested values are easier to inspect.
Configuration files
Validate application settings and download a clean JSON file after making changes.
Debugging
Find syntax errors such as missing commas, invalid quotes, and incomplete objects.
Data cleanup
Sort object keys, standardize indentation, and convert between readable and minified JSON.
