API Response Formatter

Detect, pretty-format, and analyze raw API responses, including HTTP messages, XML/YAML/CSV payloads, and double-encoded JSON bodies.

Shareable input links

You can prefill this tool by adding ?input=... to the URL. Tip: URL-encode JSON/text values before sharing.

What this formatter can normalize

Accepts plain JSON, XML, YAML, CSV, or full HTTP response text with headers and body.
JSON bodies that contain nested serialized payloads are expanded when they look like structured data.
HTTP start lines, headers, and body payloads are analyzed separately in the output report.
Plain text is left as-is when no reliable structured format can be detected.

Try these API payload examples

Choose example

HTTP/1.1 200 OK
content-type: application/json
cache-control: no-cache

{"user":{"name":"Ada","age":31},"body":"{\"meta\":{\"page\":1},\"items\":[{\"id\":1},{\"id\":2}]}"}

API Response Input

Paste a raw API payload or a full HTTP response with headers and body.

Formatting Report
