XML Beautifier for API Responses

About This Tool

Working with REST APIs, GraphQL endpoints, and webhooks means constantly processing XML response data. Raw API responses are typically minified — stripped of all whitespace and line breaks to minimize payload size — making them virtually impossible to read without formatting. This tool transforms those compact responses into well-structured, readable output that reveals the data hierarchy and makes it easy to locate specific values. Paste a response from Postman, cURL, browser DevTools Network tab, or any API client, and instantly see the formatted result. The tool validates the response structure during processing, catching malformed responses that might cause subtle bugs in your application. For developers debugging production issues, this immediate visibility into API data structures is invaluable.

What is XML Beautifier?

An XML beautifier transforms compact, machine-generated, or inconsistently formatted XML into a visually clean document with uniform 2-space indentation for each nesting level. Unlike basic text editors that may not understand XML structure, this tool parses the XML element hierarchy and applies formatting rules that reflect the logical structure of the document. This makes deeply nested XML schemas, complex configuration files, and large data exports significantly easier to read, debug, and review. The beautifier is particularly useful for XML generated by ORMs, serialization libraries, and data export tools that produce compact output optimized for machines rather than humans.

How to Use This Tool

1. Paste your XML.
