Tips for Working with Comma Separated Lists
When working with comma-separated values, keep these tips in mind:
- For text values that might contain commas, consider using quotes around each item (e.g., "Smith, John", "Doe, Jane")
- In programming languages, you may need to add square brackets or other syntax around your comma list
- For very large lists, consider breaking them into smaller chunks for better performance
- Always test your converted data in the target application to ensure proper formatting
