What Is a .tsv File?

TSV (Tab-Separated Values) files use tab characters to delimit columns in tabular plain-text data, with each row on a new line. TSV offers advantages over CSV when data fields frequently contain commas, as tabs rarely appear in natural data, reducing the need for quoting and escaping. The format is widely used in bioinformatics, computational linguistics, and data science where datasets often contain text with commas, special characters, and multi-word entries. TSV is the standard export format for many database tools and is commonly used in Unix/Linux pipelines where tab-delimited data works well with tools like cut, awk, sort, and join. The IANA media type for TSV is text/tab-separated-values, giving it a more formal standardization than CSV's often ambiguous delimiter conventions. TSV files can be opened directly in spreadsheet applications that auto-detect the tab delimiter, and most data processing libraries support TSV parsing out of the box alongside CSV support.
