What Is a CSV File?
CSV is a table as plain text: one row per line, values separated by commas. Every spreadsheet, database and programming language reads it, which makes it the universal format for exchanging data. CSV is a format rather than a compression method — plain text, one row per line. What is inside decides the quality.
