Frequently Asked Questions

What delimiter should I use?

Comma (,) is the standard delimiter for CSV files. Use semicolon (;) for European formats where commas are decimal separators. Tab is common for data copied from spreadsheets. Pipe (|) is useful when your data contains many commas.

How do I handle fields with commas?

Wrap fields containing commas in double quotes. For example: John,"New York, NY",30. If a field contains quotes, escape them with another quote: She said ""Hello"".

Is my data secure?

Yes, all conversions happen locally in your browser. Your data is never uploaded to any server, ensuring complete privacy and security for sensitive information.
