About this JSON to XML converter
Many enterprise systems, SOAP services and feeds still expect XML. This converter maps JSON objects to elements, arrays to repeated elements and escapes every value.
How JSON to XML conversion works
- Each object key becomes an element; arrays repeat the element for each item.
- Keys that aren't valid XML names (for example starting with a digit or containing spaces) are converted to valid names.
- Text is escaped and the document is indented for readability.
Conversion quality: High fidelity. Structure and values are preserved; keys that aren't valid XML names are adjusted.
When to convert JSON to XML
- Integrating with XML-based APIs
- Generating configuration for XML-based tools
Limitations to be aware of
- JSON has no concept of attributes, so all data becomes elements.
- null values become empty elements.
JSON vs XML
JSON. JSON (JavaScript Object Notation) is the most common format for exchanging structured data between web services. It supports nested objects and arrays, strings, numbers, booleans and null.
XML. XML is a markup language for structured data with elements and attributes. It remains common in enterprise systems, feeds (RSS) and document formats such as DOCX, which is XML inside a ZIP archive.
Frequently asked questions
How are arrays represented?
An array under the key “item” becomes several <item> elements in a row, which is the most common XML convention.
Are my files uploaded?
No. This tool reads and processes files directly in your web browser. Nothing is sent to Expensico's servers, and the data is discarded when you close or reload the page.
