JSON Formatter

Format / Beautify — Pretty-prints JSON with your choice of indentation (2 spaces, 4 spaces, or tab).
Minify — Strips all unnecessary whitespace to produce the most compact JSON string.
Validate — Instantly checks your JSON for syntax errors and shows the exact error message.
Stats — Shows character count, total key count, max nesting depth, and output size.

All processing happens entirely in your browser — no data is ever sent to a server.
