What is an XLSX file?
An XLSX file is a spreadsheet format introduced by Microsoft Excel 2007 and later. It stores data in rows and columns and supports advanced features such as formulas, charts, tables, and macros in a compressed XML-based format.

How to open an XLSX file
XLSX files can be opened with Microsoft Excel 2007 or newer, Google Sheets, or LibreOffice Calc. They can also be read programmatically using libraries in languages like Python, Java, or JavaScript.

Why XLSX files are used
XLSX files are widely used for data analysis, reporting, and complex calculations. Their modern structure makes them more efficient, secure, and compatible with newer software than the older XLS format.
