API Response Formatter

Data

Auto-detect and format API responses: JSON, XML, HTML, CSV

Paste a raw response body of unknown type, copied straight out of browser DevTools, and it gets auto-detected and pretty-printed as JSON, XML, HTML, or CSV without you having to guess the content type first. Detection works off structural cues: a leading `{`/`[` reads as JSON, `<` tags suggest XML/HTML, comma-delimited rows suggest CSV, falling back to plain text when nothing matches confidently, and there's a manual override if it guesses wrong. It's built for readability, not correctness checking: it doesn't validate that a response matches an expected schema, which is what the separate JSON Schema Validator tool is for. Everything runs client-side, so pasting a response body here never sends it anywhere.

  • 3.Compare two API responses side by side to spot a formatting or field difference between environments.

Frequently asked questions

How does auto-detection decide the format?
It looks at structural cues — leading `{`/`[` for JSON, `<` tags for XML/HTML, comma-delimited rows for CSV — and falls back to plain text if nothing matches confidently.
What if it detects the wrong format?
You can manually override the detected format and force it to parse as a specific type.
Is my response data sent to a server?
No, detection and formatting happen entirely in your browser.
Does it validate that the response matches an expected schema?
No, it only formats and displays the response for readability — for schema validation, use the JSON Schema Validator tool separately.
