CSV

Comma Separated Values File

CSV is a simple, widely used file format for storing tabular data in plain text, making it easy to exchange information between different applications and systems. It is supported by numerous tools, including spreadsheet software like Microsoft Excel and Google Sheets, programming languages like Python and R, and database management systems. The format consists of rows of data separated by line breaks, with each row containing values separated by commas (or other delimiters like semicolons), and it can optionally include a header row, support text encoding, and handle complex data through quoting and escaping mechanisms.

XLSB

Microsoft Excel Binary Spreadsheet File

XLSB is a binary file format used by Microsoft Excel to store spreadsheet data, offering a more compact and efficient alternative to XML-based formats like XLSX. It is primarily supported by Microsoft Excel and a few third-party tools, such as LibreOffice and Apache POI, though compatibility may vary. The format stores data in a compressed binary structure, enabling faster loading and saving times, and supports advanced Excel features like macros, charts, and complex formulas while maintaining smaller file sizes compared to XML-based formats.
