About JSON Formatter
JSON (JavaScript Object Notation) is a lightweight data interchange format. This tool helps you format, validate, and minify JSON data instantly in your browser. No data is sent to any server.
Use the formatter to pretty-print compressed JSON for readability, or minify formatted JSON to reduce size for APIs and storage. The validator checks for syntax errors and reports the exact issue.
