Best Practices

  • Validate CSV first - Use a CSV validator to check for structural issues before conversion
  • Clean headers - Use simple, descriptive column names without special characters
  • Handle empty values - Decide how to represent null/empty values in your target format
  • Test with sample - Convert a small sample first to verify the output meets your needs
  • Check encoding - Ensure your CSV is UTF-8 encoded to prevent character corruption

Limitations & Tips

File Size Limit

Maximum 10MB file size

Workaround

For larger files, split into smaller chunks or use a server-side solution

Column Count

Up to 100 columns supported

Workaround

Reduce columns by removing unnecessary fields before conversion

Data Types

All values treated as strings (except Excel which auto-detects types)

Workaround

For JSON, manually specify types after conversion if needed

Special Characters

Some special characters may need escaping

Workaround

Preview the output and verify special characters render correctly
