40 Tab-separated Values Dataset A tab-separated values file is a simple text format for storing data in a tabular structure (e.g. database or spreadsheet data). Each record in the table is one line of the text file. Each field value of a record is separated from the next by a tab stop character – it is a form of the more general delimiter-separated values format.
