Frequently Asked Questions
What formats are supported?
This tool supports JSON and XML API responses. It auto-detects the format based on the first character of your input.
Can I use this for debugging API calls?
Yes! Paste the raw response from your API client (Postman, curl, fetch) and this tool will format it so you can read and analyze the data structure easily.
Does this validate the response?
Yes. Malformed JSON will show a parse error with details. Invalid XML is validated using the browser's DOMParser and will show what went wrong.
Is my API data sent to any server?
No. All formatting happens in your browser. Your API responses never leave your device.
