Why Convert Excel to CSV?
While Excel files offer rich formatting and multiple sheets, CSV (Comma-Separated Values) format provides universal compatibility and simplicity. Converting Excel to CSV is essential for:
- Data Import/Export: Most databases, CRM systems, and analytics tools prefer CSV for bulk data operations
- System Integration: CSV serves as a common format for data exchange between different software systems
- Programming & Scripts: CSV files are easily processed by scripts and programming languages without special libraries
- Version Control: Plain text CSV files work well with Git and other version control systems
- Performance: CSV files are smaller and faster to process than Excel files

Best Practices for Excel to CSV Conversion
- Review Your Data: Check for special characters, formulas, and formatting that may need special handling
- Choose the Right Delimiter: Use commas for general purposes, semicolons for European formats, or tabs for spreadsheet compatibility
- Handle Dates Carefully: Select a consistent date format that matches your target system's requirements
- Test with Sample Data: Convert a small sample first to verify settings before processing large files
- Preserve Data Integrity: Enable quote handling for fields containing delimiters or special characters
- Document Your Settings: Note the conversion settings used for reproducibility and troubleshooting
⚠️ Important Considerations
- CSV format doesn't support formatting (colors, fonts, borders)
- Formulas are converted to their calculated values or preserved as text
- Charts, images, and other objects are not included in CSV
- Multiple sheets require separate CSV files or merging strategy
