JSON Formatter & Validator

Beautify, minify, and validate JSON locally for API payloads, config files, and structured logs. Pretty-print reveals nested objects; minify collapses whitespace for compact transport. The parser flags common mistakes such as trailing commas, single quotes, and truncated braces without uploading your JSON to ConvertWiseHub servers. Redact tokens before sharing formatted output in tickets or chat.

Why is my JSON marked invalid?

Common causes are trailing commas, single quotes instead of double quotes, unquoted keys, or truncated braces. The error panel points to the parser message.

Does formatting change data values?

No. Pretty-printing only changes whitespace and indentation. Minify removes unnecessary whitespace without altering parsed values.

Is my JSON uploaded?

Validation and formatting run in your browser. Sensitive tokens in JSON should still be handled carefully on shared devices.
