JSON to XML Converter FAQ
- How do I convert JSON to XML?
- Paste valid JSON into the input panel. The XML document appears automatically with an XML declaration and a single root element.
- How are JSON arrays handled?
- Arrays inside an object become repeated sibling elements with the same tag name. A top-level array is wrapped in root with repeated item elements.
- What happens to JSON keys that are not valid XML tag names?
- Invalid characters are replaced with underscores, empty names become item, and names that cannot start an XML element receive a leading underscore.
- Is my JSON stored or sent to a server?
- No. The conversion happens in your browser, and AppDoesIt does not store the text you paste into this tool.
- Why did I get a validation error?
- Most errors come from malformed JSON or input that is too large. Check the syntax, remove comments or trailing commas, and try again.

How to use

Tips
- Objects become nested elements, and arrays become repeated sibling elements.
- Special XML characters such as &, <, >, quotes, and apostrophes are escaped automatically.
- JSON keys that are not safe XML tag names are converted to underscore-based names.
Troubleshooting
- If conversion fails, check for trailing commas, comments, unquoted property names, or incomplete JSON.
- If a tag name looks different, the original JSON key contained characters that are not safe for XML element names.
- Inputs over 1 MB are rejected to keep the browser responsive.
Privacy and browser behavior
- Conversion runs locally in your browser; this app does not upload or store your JSON or XML.
- Clipboard access is used only after you click Paste or Copy.
