FAQs
What is XML to JSON conversion?
XML (eXtensible Markup Language) is a markup language for storing hierarchical data. JSON (JavaScript Object Notation) is a lightweight data format used in web development. Converting XML to JSON transforms XML elements into JSON objects, making it easier to use in JavaScript applications and modern APIs.
How are XML attributes handled?
By default, XML attributes are included in the JSON output under an '@attributes' key. For example, <person id="1"> becomes {"@attributes": {"id": 1}}. Check 'Ignore attributes' to exclude them from the output.
What's the difference between Object and Array mode?
Object mode (default) creates arrays only when XML elements repeat. For example, one <item> becomes an object, but multiple <item> elements become an array. Array mode always uses arrays for child elements, even if they appear only once, providing consistent structure.
How are repeated XML elements handled?
In Object mode, if an element appears once, it's a single object. If it appears multiple times, it becomes an array. In Array mode, all child elements are always arrays, even single occurrences. Choose based on whether you need consistent array structure.
What are CDATA sections?
CDATA sections (<![CDATA[...]]>) contain text that should not be parsed as XML. They're useful for including special characters or code. Our converter preserves CDATA content under a '#cdata' key in the JSON output.
Should I ignore comments?
XML comments (<!-- comment -->) are usually metadata not needed in JSON. 'Ignore comments' (enabled by default) excludes them from output. Uncheck if you need to preserve comment content in your JSON.
What does 'Trim whitespace' do?
This option removes leading and trailing spaces from all text values and attributes. For example, " John " becomes "John". This is useful for cleaning up XML with inconsistent formatting.
How are data types handled?
The converter automatically detects and converts data types: numeric strings become numbers ("30" → 30), "true"/"false" become booleans, "null" becomes null, and everything else remains a string. This makes the JSON more useful for programming.
What if my XML has parsing errors?
Click 'Validate XML' to check for syntax errors. Common issues: unclosed tags, missing quotes, invalid characters, or malformed structure. The error message will help you identify and fix the problem.
Can I format messy XML?
Yes! Click the 'Format' button to automatically add proper indentation and line breaks to your XML. This makes it easier to read and understand the structure before converting to JSON.
Is my XML data secure?
Yes! All XML processing happens entirely in your browser using the DOMParser API. Your XML never leaves your device and is not sent to any server, ensuring complete privacy and security.
