What is TSV?
TSV (Tab-Separated Values) is a text format where columns are separated by tab characters instead of commas. TSV is preferred when data contains commas, and is commonly used in bioinformatics, linguistics, and data processing pipelines.
When to convert?
Convert CSV to TSV when your data contains commas that conflict with the CSV delimiter, when pasting into spreadsheets, or when working with tools that expect tab-delimited input such as bioinformatics software and Unix command-line tools.
Frequently asked questions
Is my data safe when converting CSV to TSV?
Yes. The conversion runs entirely in your browser. Your data is never sent to any server.
What is the difference between CSV and TSV?
CSV uses commas to separate values; TSV uses tab characters. TSV is often preferred when data contains commas, as it avoids the need for quoting.
When should I use TSV instead of CSV?
TSV is useful when your data contains commas, when pasting into spreadsheets, or when working with tools that expect tab-delimited input (e.g., some bioinformatics tools).
Does it handle quoted fields?
Yes. Fields that contain commas, newlines, or quotes in the original CSV are properly handled during the conversion to TSV.
