How to use JSON Formatter
Paste your JSON into the input panel, choose your indentation preference, and click Format. The formatted output appears instantly — all processing happens in your browser.
Why process JSON locally?
Your data never leaves your browser. Unlike server-based formatters, Devault processes everything client-side, making it safe to use with sensitive API responses and production data.
