JSON to XML Converter

Convert JSON to XML and XML back to JSON, in both directions, entirely in your browser.

How to use the JSON / XML

  1. 01

    Choose a direction: JSON to XML or XML to JSON.

  2. 02

    Paste your JSON or XML.

  3. 03

    Copy the converted result, or swap to convert back.

Convert both directions

A two-way converter between JSON and XML, built on a well-tested parser. Convert a JSON object into XML or parse XML back into JSON, preserving attributes and turning repeated elements into arrays and back again.

It is handy whenever you need to bridge an XML-based system and a JSON-based one, inspect a SOAP payload as readable JSON, or turn a JSON config into the XML a legacy tool expects.

Everything runs locally in your browser, so your data never leaves your device.

Why XML is still everywhere

XML (Extensible Markup Language) is a long-established way to structure data with nested tags and attributes. It is still everywhere: SOAP web services, RSS and Atom feeds, office document formats, Android layouts and countless configuration and data-exchange formats.

How attributes are preserved

Attributes are preserved across the round trip using an @_ prefix on the JSON side, so an XML attribute becomes a clearly marked JSON key and converts back into the same attribute, rather than being lost or confused with child elements.

Repeated elements become arrays

Repeated elements map naturally to arrays: several <item> tags under a parent become a JSON array, and a JSON array becomes repeated elements in the XML, which is the shape most real documents take.

Frequently asked questions

How are XML attributes handled?

Attributes are preserved using an @_ prefix on the JSON side, so converting back and forth keeps them intact.

How are repeated elements represented?

Repeated XML elements become a JSON array, and arrays in JSON become repeated elements in XML.

Is my data uploaded to a server?

No. The conversion runs entirely in your browser, so your data never leaves your device.

What is XML still used for?

Plenty: SOAP web services, RSS and Atom feeds, office document formats, Android layouts, and many configuration and data-exchange formats where it remains the standard.

Is converting between JSON and XML always lossless?

Usually, but the models differ. Attributes, text and repeated elements map cleanly, while XML-specific features like comments, namespaces and mixed content do not always have a JSON equivalent.
