XML to JSON Converter

Convert XML feeds to JSON entirely in your browser. Processing stays on your device.

How to Use

  1. Paste XML or upload a file.
  2. Convert to JSON.
  3. Copy or download the pretty-printed result.

Key Features & Privacy Advantage

  • All processing happens locally in your browser. Your files are never uploaded to a server.
  • DOMParser-based conversion.
  • Pretty-printed JSON.
  • Clear parse errors.

Technical Breakdown

DOMParser builds an XML tree; we recursively map elements, attributes, and text nodes into JSON. Repeated sibling tags become arrays. Mixed content may need manual shaping for APIs.

Frequently Asked Questions

Is XML uploaded?

No. All processing happens locally in your browser. Your files are never uploaded to a server.

Attributes?

Attributes are mapped into the JSON structure with a clear convention in the output.

Invalid XML?

Parser errors are shown so you can fix the source.

Huge feeds?

Very large XML may be slow in-browser; filter upstream when possible.
