JSON to XML Converter Online

Control how JSON becomes XML instead of accepting opaque defaults. Set root and item names, decide how nulls and strings are represented, and review the document before sending it to another system.

Direct answer

A JSON-to-XML converter maps object keys to element names and arrays to repeated item elements. JSON does not define XML attributes, namespaces or mixed content, so target-specific XML contracts may need manual adjustments.

Choose the XML mapping options and verify the document against the target system.

How to use it

  1. Paste/upload JSON or fetch a supported public URL.
  2. Set root/item names, indentation, null strategy, CDATA, declaration and empty-element behavior.
  3. Review the XML structure, copy/download it and validate it in the receiving system.

Key features and settings

  • Custom root and array-item element names.
  • Configurable null representation and self-closing empty nodes.
  • Optional CDATA strategy, XML declaration and pretty formatting.
  • Live preview plus copy/download actions.

Supported input and output

Input: JSON text or file, a supported public URL. Output: .xml.

Use cases

  • Create XML for a legacy integration from a JSON payload.
  • Prototype data mappings before building a production transformation.
  • Convert simple record arrays into repeated XML elements.

Which workflow should you choose?

Use JSON to XML Converter for: Custom root and array-item element names. Use Excel to XML Converter for: Worksheet selection and multiple cell-mapping styles.

Privacy and data path

In the current implementation, pasted/uploaded content is processed in the browser, while “Extract from URL” uses a server-side proxy to fetch the source.

Limits and troubleshooting

  • Keys that are not valid XML names and contracts requiring namespaces/attributes need manual mapping.
  • URL extraction uses a server proxy; display that disclosure next to the URL input rather than a blanket “no upload” claim.
  • The current UI displays a 5 MB input limit.

FAQ

How are JSON arrays represented in XML?

Array items become repeated elements using the configured item name. Check ordering and wrappers against the receiving system’s expected structure.

Is my data uploaded to a server?

In the current implementation, pasted/uploaded content is processed in the browser, while “Extract from URL” uses a server-side proxy to fetch the source.

What are the file or data limits?

The current UI displays a 5 MB input limit.

Does it work on mobile?

The page is web-based and may work in a modern mobile browser, but file-picker behavior, memory and cross-device compatibility are not verified for every device. Use a desktop browser for large or complex inputs.

Which workflow should you choose?

Use JSON to XML Converter for: Custom root and array-item element names. Use Excel to XML Converter for: Worksheet selection and multiple cell-mapping styles.
