什么是.xlsx文件？

XLSX is the default file format for Microsoft Excel spreadsheets since Office 2007. It stores data in cells organized into rows and columns, supporting formulas, charts, pivot tables, conditional formatting, and macros. The format is based on Open XML and uses ZIP compression, making files significantly smaller than the older .xls format. XLSX is the industry standard for business data analysis, financial modeling, and data management.
