API Response Formatter
Beautify and syntax highlight JSON/XML responses.
Use this free online API Response Formatter to cleans and indents raw JSON payloads from API calls for debugging and code review. It fits developer, QA, and operations workflows where pasted payloads, configuration values, or text artifacts need fast inspection and cleanup. The form focuses on Response Type, Raw Response and returns Formatted Output, so you can move from input to answer without setting up a spreadsheet or custom script. Run one realistic example, adjust the inputs, and compare how the result changes before you copy or share it. Avoid pasting production secrets unless your local policy allows it, and validate generated output in the target system before relying on it.
