API Response Formatter

Instantly beautify JSON, XML, or HTML responses from your API calls.

How to Format API Responses?

Debugging APIs can be frustrating when the response is a single minified line of text. Our tool helps you visualize the data structure instantly.

  1. Paste Raw Data: Copy the minified body from your browser network tab, Postman, or console log and paste it into the "Raw Response" box.
  2. Auto-Detect: The tool automatically identifies if the content is JSON, XML, or HTML.
  3. View & Analyze: See your data in a clean, color-coded, tree-like structure. Syntax highlighting helps spot errors immediately.

Supported Formats

JSON

The standard for REST APIs. We handle nested objects and arrays with ease.

XML

Common in SOAP APIs and RSS feeds. We indent tags properly for readability.

HTML

Great for debugging web scrapers or server-side rendered pages.

Frequently Asked Questions

Yes. This is a client-side tool. Your API data is processed entirely within your browser and is never sent to our servers.

To a degree. If the JSON is slightly malformed (e.g., missing quotes on keys), our parser may attempt to interpret it, but strictly invalid JSON will trigger an error to alert you.
