What is the XML Mock Data Generator?
The XML Mock Data Generator creates realistic XML test data from a JSON Schema or template definition. It generates JSON internally using Faker.js, then converts it to well-formed XML — no backend, no signup.
Features
- Two input modes: JSON Schema (Draft 07+) or Template / Hint mode with
{{faker.*}}directives - Smart type inference: Empty or null values are automatically filled based on property key names
- Well-formed XML output: Proper encoding, tag naming, and nesting
- Deterministic seeding: Same input + seed = identical output every time
- Multi-locale support: 26+ locales for localized data
- Bulk generation: Generate thousands of records
- Copy & download: One-click copy to clipboard or download as .xml
Use Cases
- API testing: Generate XML payloads for SOAP or REST XML APIs
- Legacy system integration: Test XML-based data exchange formats
- Configuration file generation: Create sample XML config files
- XSLT transformation testing: Generate source XML for stylesheet development
- Demo environments: Quick XML datasets for presentations
How It Works
Write a JSON Schema or a template object. The engine generates JSON internally using Faker.js, then converts it to XML with a <root> element. Object keys become element names; arrays produce repeated elements; primitives become text content.
Frequently Asked Questions
Is my data sent to a server?
No. All generation happens in your browser. Your data never leaves your computer.
How are arrays handled in XML?
Array items are output as repeated sibling elements with the same tag name, derived from the parent key.
What XML encoding is used?
UTF-8 with XML declaration (<?xml version="1.0" encoding="UTF-8"?>). Special characters (<, >, &, quotes) are properly escaped.
How many records can I generate?
Up to 10,000 records per request.
Are XML attributes supported?
Currently, the generator uses elements only. Attribute support is planned for a future release.
