TSV is a plain-text table format storing tab-separated values. Opened in Excel and any text editor. TSV is the tab-separated cousin of CSV, useful when the data itself contains commas. Because tabs almost never appear inside ordinary text, TSV needs no quoting or escaping rules, unlike CSV where stray commas force complex quoting. The text/tab-separated-values media type was registered in the early 1990s by the University of Minnesota team behind the Gopher protocol. TSV is popular in bioinformatics and large data pipelines, where its rigid one-tab-per-field rule makes parsing fast and unambiguous. A .TSV file is plain text, so you can open and edit it in any text editor.

Drop a .TSV file onto Analyser at https://analyser.valjdakosta.com/ and it opens directly in your browser - no upload, no account and no software to install. Open CSV and TSV tables in a full analysis workbench: a virtualised grid with sort, filter, per-column and global search, column show/hide/reorder and column splitting, a group-by summary, and a chart builder (line, bar, scatter, histogram, pie, area, box and heatmap) with PNG/JSON/CSV export.
