Output files are UTF-8 text. JSON output is intentionally minified for streaming performance, so it may open as a single line until you run your editor's format command.
Frequently Asked Questions
How does XML to JSON conversion work?
Convert Buddy parses your XML file and extracts structured records based on detected patterns. The XML elements are mapped to JSON objects while preserving the data hierarchy. Our streaming parser handles files of any size without loading everything into memory.
Is my data safe when converting XML to JSON?
Yes, absolutely. Convert Buddy runs entirely in your browser using WebAssembly. Your files never leave your device — no uploads, no servers, no tracking. All processing happens locally on your machine.
What size XML files can I convert?
Convert Buddy uses a streaming architecture that processes files in chunks, so there is no hard limit. We have successfully tested with multi-GB XML files. The conversion happens progressively with real-time performance metrics.
Can I customize how XML converts to JSON?
Yes. Convert Buddy detects the XML structure automatically, but you can configure record elements, field mappings, and transformations in the advanced options. You can also choose between different output formats (standard JSON or NDJSON).
Do I need to install anything?
No installation needed. Convert Buddy runs directly in modern browsers (Chrome, Firefox, Safari, Edge). The WebAssembly engine loads automatically when you visit the page.
