Collection FAQ
Extra context around when to use this toolkit and where to start.
How do I format XML online?
Use XML Beautifier. Paste any compressed or unformatted XML and it indents the markup with consistent spacing and line breaks. You can also use XML Pretty Print for a read-only formatted view, or XML Highlighter to add syntax colouring.
How do I convert XML to JSON?
Use XML to JSON Converter. Paste your XML and it produces a JSON object preserving the element hierarchy, attributes, and text content. Useful when consuming XML APIs in JavaScript or Python applications that prefer JSON.
How do I validate XML online?
Use XML Validator. Paste your XML document and it checks for well-formedness errors such as unclosed tags, mismatched elements, and illegal characters. It reports the exact line and column of each error.
What is XPath and how do I test it?
XPath is a query language for selecting nodes in an XML document. Use XPath Tester — paste your XML in one panel and your XPath expression in the other to see the matching nodes highlighted instantly. Supports XPath 1.0 expressions including axes, predicates, and functions.
How do I convert XML to CSV?
Use XML to CSV Converter. Paste your XML and it flattens the repeating element structure into rows and columns. Best suited for XML that represents a list of records with consistent fields. For irregular XML trees, XML to JSON is often a better starting point.
How do I generate C# or Java classes from XML?
Use XML to C# or XML to Java Converter. Paste a sample XML document and it infers the data structure and generates a class with matching properties and types. Useful for quickly creating model classes when integrating an XML-based API.
