About JSON Formatter

Updated Jan 2025

The JSON Formatter takes raw or minified JSON and outputs a clean, indented, human-readable version. Choose between 2-space, 4-space, or tab indentation. Ideal for inspecting API responses, debugging configuration files, and sharing readable JSON with teammates. All processing happens entirely in your browser — no data is ever sent to a server.
