About CSV

CSV is a simple text format used to store tabular data, such as spreadsheets or databases. Each line represents a row, and values are separated by commas. CSV files are supported by nearly all spreadsheet and data-processing programs, making them a universal choice for data exchange.

About XLS

XLS is the original spreadsheet file format for Microsoft Excel (up to version 2003). It stores data in rows and columns, with support for formulas, charts, and macros. XLS files have been largely replaced by the newer XLSX format.
