How JSON to XML conversion works
This tool parses your JSON and writes an XML document using predictable rules. Objects become nested elements, arrays become repeated item elements, and values become text nodes. Everything runs locally in your browser, so nothing is uploaded or stored.
When to use this tool
JSON is great for modern apps, but many platforms still require XML for imports and feeds. JSON to XML helps when you need compatibility, exports, or integration with XML-based systems.
- Imports: convert API JSON into XML for older systems.
- Feeds: generate XML for marketplaces or integrations.
- Legacy tools: export data to XML for software that does not support JSON.
- Automation: transform JSON into XML in a repeatable, offline way.
Need the “reverse” direction (XML → JSON)? Try our XML to JSON Converter. If you need a CSV format instead, use this JSON to CSV Converter.
Conversion rules
- Root tag: your XML document starts with the root tag you choose (default
root). - Objects: keys become tag names and values become nested nodes.
- Arrays: each array value becomes an item tag (configurable, default
item). - Attributes: if enabled, keys that start with
@become attributes on the current element. - Text value: if an object has a
#textkey, it becomes the element’s text content. - Escaping: special characters are escaped to keep XML valid.
Step-by-step: from JSON to XML
Converting your JSON takes just a few seconds:
- Add your JSON files. Drag and drop files into the box above, or click to choose from your device.
- Set tags. Choose a root tag and array item tag (optional).
- Pick options. Decide whether to treat
@keys as attributes and output pretty formatting. - Convert to XML. Click Convert to XML. The tool processes everything locally.
- Save your output. Save files one by one or use “Save all” once ready.
Privacy, limits and how this tool treats your files
FileYoga is built around a simple rule: your files stay with you. JSON to XML conversion runs locally in your browser, so your data is never uploaded to FileYoga servers.
Local-only conversion
Conversion runs locally in your browser on your device. Your JSON is not uploaded, and the XML output is generated on your side.
No hidden copies
When you clear the list or close the tab, the tool stops using your files and does not save copies on a server.
No artificial limits
No paywalls or quotas. The only limits come from your device’s memory and your browser.
No account required
Use the converter without signing up. Open the page, convert your files, and leave when you are done.
Tips for best results
- Use simple tag names (letters, numbers, underscores, hyphens). XML tag names cannot start with a number.
- If your JSON is a top-level array, this tool will wrap it under your root tag as repeated item tags.
- To force attributes on a node, place keys like
"@id"inside the same object. - For huge JSON files, convert one file at a time to reduce memory pressure.
Troubleshooting
- Invalid JSON error: Your file may not be valid JSON. Validate it and try again.
- Weird tag names: Keys with spaces or symbols are sanitized. Rename keys if you need strict tag naming.
- Attributes not showing: Enable “@keys become attributes” and use keys like
"@id". - XML looks too verbose: Switch formatting to Compact.
- The tab freezes: Very large or deeply nested JSON can hit memory limits. Convert one file at a time and close other heavy tabs.
Frequently asked questions
No. JSON to XML conversion runs locally in your browser. Your file is never uploaded to FileYoga servers, and the XML output is generated on your device.
Use tag names that match the system you’re exporting for. Common root tags include root, data, catalog, or response.
The item tag is used for arrays (default item). If you’re unsure, keep the defaults and adjust later.
Arrays become repeated elements using your item tag. For example, an array under a key becomes:
multiple <item>...</item> nodes inside the parent element.
You can change the item tag if your target system expects a specific name.
Top-level arrays are wrapped under your root tag so the XML stays valid (XML needs a single root element). The array items then become repeated item-tag elements under that root.
If enabled, keys that start with @ become attributes on the current element.
Example: {"@id":"123"} becomes id="123".
If an object contains a #text key, that value becomes the element’s text content.
When an element needs both text and nested elements, the converter preserves everything. Depending on the structure, text may be kept as the element’s text content (when it has no children), or stored in a dedicated child node to avoid losing data. If your target system requires a specific mixed-content layout, you can tweak the JSON structure before converting.
XML tag names must follow stricter rules than JSON keys. If a key contains spaces or special characters,
the converter sanitizes it to keep the XML valid (for example replacing invalid characters with underscores).
For best results, use simple keys like product_id or orderNumber.
No. Characters like &, <, and > are safely escaped in text and attribute values,
so the output remains valid XML.
Pretty formatting adds indentation and line breaks so the XML is easy to read. Compact formatting removes extra whitespace for smaller files and faster transfers. Both represent the same data.
There are no artificial limits. Very large or deeply nested JSON files can hit browser memory limits or slow down your device. If that happens, convert one file at a time and close other heavy tabs.
