Output
Output will appear here after conversion completes.
Format: Unknown → JSON
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.
Try with sample data
Load example files directly in the converter to see how Convert Buddy handles different formats. Sample files are embedded in the page for instant testing.
