What is TSV to CSV Conversion?
TSV (Tab-Separated Values) and CSV (Comma-Separated Values) are both plain text formats for storing tabular data. TSV uses tab characters to separate fields, while CSV uses commas.
Converting from TSV to CSV is useful when you need to import data into applications that expect CSV format, such as spreadsheet software, databases, or data analysis tools.
This tool handles the conversion automatically, including proper quoting of fields that contain commas, quotes, or other special characters. All processing happens in your browser for privacy.
Features
Automatic Quoting
Fields containing commas, quotes, or newlines are automatically wrapped in double quotes.
Quote Escaping
Existing double quotes in data are properly escaped by doubling them (RFC 4180 compliant).
Quote All Option
Optionally wrap all fields in quotes for maximum compatibility.
Data Statistics
View row count, column count, and file size after conversion.
Download & Copy
Download the converted CSV as a file or copy it directly to your clipboard.

TSV vs CSV Format
TSV (Tab-Separated Values): Uses tab characters (\t) as field delimiters. Simple format that rarely needs quoting since tabs are uncommon in data.
CSV (Comma-Separated Values): Uses commas as field delimiters. More widely supported but requires quoting when fields contain commas.
Quoting Rules: In CSV, fields containing commas, double quotes, or newlines must be enclosed in double quotes. Double quotes within fields are escaped by doubling them.
Compatibility: CSV is more universally supported by spreadsheet applications, databases, and programming languages.
Frequently Asked Questions
When should I use TSV vs CSV?
Use TSV when your data contains many commas (like addresses or numbers with thousands separators). Use CSV for broader compatibility with spreadsheet applications and databases.
How are special characters handled?
Fields containing commas, double quotes, or newlines are automatically wrapped in double quotes. Existing double quotes are escaped by doubling them (e.g., " becomes "").
What is the "Quote all fields" option?
This option wraps every field in double quotes, even if they don't contain special characters. This ensures maximum compatibility with all CSV parsers but increases file size.
Is my data secure?
Yes. All processing happens entirely in your browser using JavaScript. Your data never leaves your device and is not sent to any server.
