Frequently Asked Questions

How do I convert TSV to CSV?
Paste your TSV data into the input field or upload a .tsv/.txt file. The tool automatically detects tab characters and converts them to comma-separated values. Fields containing commas, quotes, or newlines are properly quoted according to CSV standards.
How does it handle fields with commas?
Fields containing commas, quotes, or newlines are automatically wrapped in double quotes. If a field contains a double quote, it's escaped by doubling it (e.g., 'John "Joe" Smith' becomes '"John ""Joe"" Smith"'). This follows CSV RFC 4180 standards.
What's the difference between TSV and CSV?
TSV (Tab-Separated Values) uses tab characters (\t) as field delimiters, while CSV (Comma-Separated Values) uses commas. TSV is often easier to work with when data contains commas, but CSV is more widely supported by spreadsheet applications and databases.
Does it preserve special characters?
Yes! The converter preserves all special characters including Unicode, emojis, newlines within fields, and quotes. It properly escapes them according to CSV RFC 4180 standards, ensuring your data remains intact during conversion.
Can I upload a TSV file?
Yes! Click the "Upload .tsv/.txt" button to upload a file from your device. The converter supports .tsv, .txt, and other text-based tab-delimited formats. The entire file is processed in your browser without uploading to any server.
