What is a TSV file?
Stores a data table in which columns of data are separated by tabs; TSV files can be imported into most spreadsheet programs, which format the data into cells; they can also be exported by spreadsheet programs, which allows the data to be viewed with a basic text editor or word processing program.
Another popular format for exporting spreadsheet data is .CSV, which uses commas to separate columns instead of tabs.
