What is a TSV File?

TSV (Tab-Separated Values) is a widely used plain text format for tabular data. Columns are separated by tab characters, rows by newlines. TSV is often used for data exchange, database exports, logs, and spreadsheets, compatible with Excel, Google Sheets, and all programming languages.
