APIs, config files, and data payloads all use JSON. When you're debugging a 500-line response or building a request body, readable formatting makes the difference between guessing and understanding. This tool formats, minifies, and validates JSON entirely in your browser — nothing gets sent to a server.
Format with 2 or 4 space indentation. Minify to a single line for compact payloads. Validate with precise error location (line and column). See structure stats: key count, nesting depth, object and array counts, and byte size comparison between formatted and minified. All processing happens client-side — your data never leaves your browser.
