Frequently Asked Questions
JSON to XML conversion transforms JavaScript Object Notation data into eXtensible Markup Language format. JSON uses key-value pairs and arrays, while XML uses nested elements with opening and closing tags. This tool recursively maps JSON structures to equivalent XML hierarchies, preserving data types, nesting levels, and array repetitions.
Nested JSON objects are converted into nested XML elements. Each key in the object becomes an XML tag, and its value becomes the content or child elements. For example, {"address": {"city": "NYC"}} becomes <address><city>NYC</city></address>. There is no depth limit — the tool handles arbitrarily deep nesting.
JSON arrays create repeated XML elements using the parent key as the tag name. For example, {"items": ["A", "B"]} becomes <items><item>A</item><item>B</item></items>. Each array element gets wrapped in a singularized version of the key name (e.g., "items" becomes "item").
Numbers and booleans are converted to their string representations in XML text content. Null values produce empty self-closing elements like <field/>. This ensures all JSON data types have a valid XML representation without data loss or ambiguity.
Yes. The tool provides an input field to set your preferred root element name. The default is "root", but you can use any valid XML tag name such as "data", "response", "config", "document", etc. The root element wraps your entire converted JSON structure as the outermost XML tag.
No, never. All JSON parsing and XML generation happen entirely within your browser using JavaScript. No data is transmitted, uploaded, or stored on any server. Your information remains completely private at all times. You can verify this by disconnecting from the internet — the tool will still work.
The tool supports JSON input up to 200,000 characters. For most practical use cases including API responses, configuration files, and data exports, this limit is more than sufficient. Extremely large files may take slightly longer to process depending on your device performance.
Yes. The tool is fully responsive and optimized for mobile browsers. The layout switches to a single-column view on smaller screens, textareas use large touch-friendly controls, and all buttons expand to full width on mobile. XML output scrolls internally to prevent horizontal page scrolling.
Pretty print formats the XML output with proper indentation (2 spaces per level) and line breaks between elements. This makes the XML highly readable for humans. When disabled, the output is a single continuous string without whitespace — useful for minimizing file size in production environments.
JSON keys containing special characters (spaces, hyphens, dots, etc.) are automatically sanitized into valid XML tag names. The tool replaces invalid characters with underscores and ensures the resulting tag name starts with a letter or underscore, complying with XML naming rules.
All JSON parsing and XML generation are performed entirely in your browser. No data is uploaded or stored.
