What XLS and CSV files are

XLS

XLS is the legacy Microsoft Excel 97-2003 workbook format. It stores spreadsheets with formulas, charts, and formatting in the classic binary BIFF structure that predates XLSX.

CSV

CSV (Comma-Separated Values) is a plain text format for storing tabular data where each row is a line and values are separated by commas. It is universally compatible with all spreadsheet and database applications.
