XLSX（Microsoft Excel Open XML 电子表格）

XLSX 是 Microsoft Excel 自 2007 以来的默认电子表格格式。它将表格数据、公式、图表、数据透视表和单元格格式存储在由 XML 文件组成的 ZIP 压缩包中。XLSX 是商业数据分析和报告中最广泛使用的格式。

MIME 类型

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet

类型

二进制

压缩

无损

优点

+ Supports complex formulas, pivot tables, and conditional formatting
+ Smaller files than .xls due to ZIP compression
+ Open standard readable by LibreOffice, Google Sheets, and programmatic tools
+ Handles over one million rows per worksheet

缺点

− Heavy files with many formulas can be slow to open and recalculate
− Complex macros require .xlsm and may not work outside Excel
− Not suitable for simple data exchange — CSV is often better

何时使用 .XLSX

当电子表格需要公式、图表或多个工作表时请使用 XLSX——财务模型、数据分析、库存清单和报告。

技术细节

XLSX 文件是一个 ZIP 压缩包，包含用于工作表、共享字符串、样式和计算链的 XML 文件。单元格引用、公式和数据类型以 SpreadsheetML 标记编码。

历史

Microsoft 于 2006 年与 Office Open XML 标准一同推出了 XLSX。它取代了二进制 .xls 格式，并被标准化为 ECMA-376 和 ISO/IEC 29500 的一部分。
