About
Formator automatically turns raw JSON, JSON5, YAML, Markdown, .env, INI, Properties, and SQL into a clean, readable viewer — right in your browser tab.
Open an API response, a .json file, a YAML config, a SQL dump, or any supported text format, and Formator replaces the plain text with pretty-printing and syntax highlighting. No redirects. No uploads. Everything stays on your device.
