What's the difference between TSV and CSV?

TSV uses tab characters to separate fields, while CSV uses commas. Both are plain-text formats for tabular data. CSV is the more widely supported format — most tools, APIs, and spreadsheet applications expect CSV. TSV is common in database exports and log files.

Why can't I just replace tabs with commas?

A simple find-and-replace breaks when a field already contains commas. For example, a TSV field 'Smith, Jr.' would be split into two columns in the CSV. The converter detects these cases and wraps the field in quotes, preserving it as a single value.

What happens to fields that contain quotes?

If a field contains double-quote characters, the converter escapes them by doubling the quotes (e.g., " becomes ""), which is the RFC 4180 standard. The field is also wrapped in quotes if it's not already. This ensures the CSV parses correctly in all readers.

Can I convert CSV to TSV?

This tool converts TSV to CSV. For the reverse conversion (CSV to TSV), you would need a different tool. The conversion logic is different because going from CSV to TSV requires unquoting fields and replacing commas with tabs.

Is my data safe during conversion?

Yes. All processing happens locally in your browser. Your TSV data is never uploaded to any server. This is especially important for database exports, log files, and other sensitive tabular data.
