Why You Need an API Response Viewer
Working with APIs means dealing with raw JSON and XML responses that are often minified and unreadable. An API response viewer formats these responses instantly, making debugging faster and easier.
Key Features
JSON formatting with syntax highlighting and indentation
XML support for SOAP and legacy APIs
Error detection for malformed responses
Collapsible tree view for nested data
Copy formatted output with one click
How to Use
Open the [API Response Viewer](/tools/api-response-viewer)
Paste your raw API response into the input
Select the format (JSON or XML)
View the beautifully formatted output
Copy the result for documentation or debugging
Common Use Cases
Debugging API Integrations
When an API returns unexpected data, formatted output makes it easy to spot issues.
API Documentation
Format responses for clean examples in your documentation.
Learning APIs
Explore the structure of new APIs by visualizing their responses.
Tips
Validate first — check if the response is valid JSON/XML
Look for nested objects — important data is often deeply nested
Check status codes — the response body alone doesn't tell the full story
