About JSON Formatter

This JSON formatter and validator helps you quickly format, minify, and validate JSON data. Paste your raw JSON into the input area and choose your preferred indentation style.

Format pretty-prints your JSON with consistent indentation. Minify removes all whitespace to produce the smallest possible output. Validate checks your JSON for syntax errors and reports the exact line and column where the error occurs.

All processing happens in your browser — your data never leaves your device.
