When You Need Beautified JSON

API responses and log files often contain minified JSON — a single line of text with no whitespace. Readable for machines, unreadable for humans. Beautifying adds indentation and line breaks so you can quickly scan the structure, find specific keys, and understand nested relationships.

Formatting vs. Validating

Formatting changes how JSON looks (whitespace and indentation) without changing its data. Validation checks whether the JSON is syntactically correct. This tool does both: it formats valid JSON and shows detailed errors for invalid JSON.
