Data Utility
JSON ↔ XML Converter
Instantly convert JSON to XML and XML back to JSON, in either direction.100% Client-Side. Your data never leaves your browser.
Data Utility
Format Conversion
Turn a JSON array into a simple XML document (one element per object, one child tag per key), or flatten record-style XML back into JSON objects. Values stay as text, so leading zeros and ID codes survive the round trip.
- JSON to XML (row and field elements)
- XML to JSON (objects from records)
- Values kept as text by default
Need deeply nested XML or real transformation?
A flat swap is step one. To map data into a specific nested XML schema, reshape records, apply business logic, or validate every row before import, you need a dedicated transformation engine, not a converter.
Client-Side Processing ArchitectureSecure
Your data never leaves your device. All processing happens locally in your browser's memory via WebAssembly/JavaScript. This ensures complete data sovereignty and compliance with GDPR, HIPAA, and SOC2 standards as no files are uploaded to our servers.
Frequently Asked Questions
How do I convert JSON to XML?▼
Paste or upload a JSON array of objects. The tool wraps the data in a <rows> root and writes one <row> element per object, with one child tag per key. Click the JSON/XML toggle to convert in the other direction.
What XML structure does it produce?▼
A simple, standard record structure: an XML declaration, a <rows> root, a <row> element per object, and a child element named after each key. Keys are sanitized into valid XML tag names, and any nested objects or arrays are written into the element as JSON text.
Can it convert XML back to JSON?▼
Yes, it is fully two-way. Each direct child of the root element becomes an object, its child tags become keys, and every value is read back as text so nothing is silently retyped.
Will it keep my values exactly as written?▼
Yes. Values are treated as text on both sides, so leading zeros, ZIP codes, and long account numbers are never reformatted or turned into numbers.
Is my data secure?▼
Yes. Conversion runs 100% in your browser. Your file is processed locally in memory and is never uploaded to our servers.
