Tentang
JSON (JavaScript Object Notation) is the most common data interchange format on the web. APIs, configuration files, log lines, and front-end state all use it — but raw JSON is often hard to read. A JSON formatter turns dense, minified output into an indented, human-readable structure so you can spot missing commas, trailing braces, and stray quotes at a glance.
Our JSON Formatter runs entirely in your browser. Paste your JSON, click Format, and the result appears instantly with proper indentation, syntax highlighting, and inline error reporting. Use Minify to strip whitespace for transmission, or Validate to check syntax without rewriting the input.
The tool handles payloads up to several megabytes on modern hardware and never sends your data to a server. That makes it safe for inspecting tokens, internal config, or anything sensitive. There is no upload step, no telemetry, and no signup — open the page and start formatting.
For automation or batch validation, the same logic is available as an API endpoint (coming soon). Sign up to be notified when it launches.
