What is the main difference between TSV and CSV?

TSV uses tab characters (`\t`) to separate fields, which rarely appears in regular text. CSV uses commas (`,`), which frequently appear in human text and numbers, requiring strict quotation rules.

How does this tool handle cells that already contain commas?

Any cell containing a comma, double quote, or newline is automatically enclosed in double quotation marks (`"..."`) per RFC 4180 standards.

Can I convert European semicolon-delimited CSV files?

Yes. You can select semicolon (`;`) as the target delimiter to support European locale Excel spreadsheets that use commas for decimals.

Is there a limit on how many rows I can convert?

The converter handles tens of thousands of rows smoothly within your browser memory with zero server lag.

Does this converter store my sensitive business data?

No. All conversion algorithms execute purely in your local JavaScript environment.
