FAQ
What is XML to JSON Converter?
XML to JSON Converter transforms XML documents into JSON format. Input: XML text or file. Output: JSON object with nested structure. Use case: API response conversion, config migration, data integration.
How are XML attributes handled?
Attributes become properties prefixed with "@". Example: <user id="1"> becomes {"user":{"@id":"1"}}. Text content: stored in "#text" property. Mixed content (text + elements): may lose ordering.
What about XML namespaces?
Namespaces preserved as prefixes. Example: <ns:user> becomes "ns:user" key. Namespace declarations (xmlns): included as attributes. To remove namespaces: pre-process XML or use advanced options.
Can I convert large XML files?
Browser limit: ~30MB XML input. Processing time: ~5 seconds per 10MB. For larger files: use streaming parser or split XML. Memory usage: 4-5x input size due to DOM parsing.
How are arrays represented?
Repeated elements become JSON arrays. Example: <item>1</item><item>2</item> becomes {"item":["1","2"]}. Single element: becomes string, not array. To force arrays: use advanced options.
Does it validate XML?
No validation against DTD or XSD. Parses well-formed XML only. Invalid XML: returns error with line number. To validate: use XML Validator tool first. Schema checking: not supported.
What encoding is supported?
Input: UTF-8, UTF-16, ASCII. Output: UTF-8 JSON. Special characters: escaped (\uXXXX). CDATA sections: converted to text. Comments: ignored. Processing instructions: ignored.
Can I customize the output?
Basic version: no customization. Default: attributes with "@" prefix, text in "#text". For custom mapping: use XSLT transformation or advanced JSON mapping tools.
Pro Tip
💡 Tip: For large files, consider compressing or splitting them first for faster processing. When batch processing, you can upload multiple files at once and the tool will process them automatically.
