Example Conversion

Input (JSON):

{
  "name": "John",
  "age": 30,
  "city": "New York"
}

{
  "name": "John",
  "age": 30,
  "city": "New York"
}

Output (XML):

<root>
  <name>John</name>
  <age>30</age>
  <city>New York</city>
</root>

<root>
  <name>John</name>
  <age>30</age>
  <city>New York</city>
</root>

Output (YAML):

name: John
age: 30
city: New York

name: John
age: 30
city: New York

Output(.properties):

name=John
age=30
city=New York

name=John
age=30
city=New York

Technology Stack

Implements the core conversion logic is 100% client-side Javascript only. It uses:

• js-yaml for YAML parsing/formatting
• fast-xml-parser for XML parsing/formatting
• Native JSON methods for JSON handling

Known Limitations

1. Large Data Sets
   • Very large data structures may impact performance
   • Complex nested structures may take longer to convert
2. XML Specifics
   • XML attributes are converted to object properties with @ prefix
   • XML namespaces are not fully supported
3. YAML Specifics
   • Some advanced YAML features may not be supported
   • Multi-document YAML is not supported
4. Properties specifics
   • Data with more than a level deeper can’t be converted to properties properly

Data Format Converter Future Enhancements

1. Additional Formats
   • Support for CSV, TOML, and other common formats

2. Advanced Features
   • Schema validation
   • Format auto-detection
   • Batch conversion
3. UI Improvements
   • Syntax highlighting
   • Side-by-side comparison view
4. Performance Optimizations
   • Web Workers for large conversions
   • Streaming processing for very large files

Privacy & Security

• 🔒 100% Client-Side Processing: All conversions happen in your browser
• 🚫 No Data Storage: Your data is never saved or transmitted to any server
• 💻 Offline Capability: Works without an internet connection once loaded

Troubleshooting

Conversion fails with “Invalid format” error

• Cause: Input data doesn’t match the selected format
• Solution:
  1. Verify the input format is correctly selected
  2. Check for syntax errors in the input data
  3. Use the example templates as reference

Output looks incorrect

• Cause: Different formats handle data structures differently
• Solution:
  1. Check for known format differences (e.g., XML attributes vs JSON properties)
  2. Try converting back to original format to verify round-trip consistency

Tool doesn’t respond

• Cause: Possible JavaScript error or conflict
• Solution:
  1. Check browser console for errors
  2. Refresh the page
  3. Ensure all required scripts are loaded
