| Technical Details | The xlsx filename extension is a compressed archive with an xml directory structure. It is specified in the open standard ISO/IEC 29500-1:2012. .xlsx files do not support macros by design, for that, the .xlsm format should be used. A free compatibility update allows older versions of Microsoft Office Excel such as Office 2003 to open .xlsx documents. |
