About this tool
Format, validate, and minify JSON
Paste JSON to validate syntax, pretty-print indentation, or minify size. Useful for API debugging, config cleanup, and inspecting webhook payloads in email-related flows. Processing stays in the browser.
Tips
Invalid JSON surfaces a parse error. After formatting, pair with the hash generator for digest checks or the Base64 tool for nested encoded fields.
