这不是针对所有场景的完整解决方案，因为我没有时间绘制每个 xml，但这应该让任何人开始遇到类似的情况。
希望这将节省其他人开发类似东西的时间，下面的代码将 xlsx 转换为 zip 文件，解压缩，然后映射不同的 xml 以创建电子表格的虚拟表示。
这不是最快的代码，但如果您正在寻找速度，那么无论如何您都不会使用 Powershell。
<#
$columnListOfTuples and $rowListOfTuples have everything mapped
Each xlsx file is a compressed group of xml files into a zip file that is renamed .xlsx
There is an xml of shared strings that are then represented by a single numerical value to save space
There is an xml for each sheet in the spread sheet that has numerical references to the values in the shared strings xml
To produce a virtual/programmatic representation of the spreadsheet, the code will read the sheet, then read the numerical reference than then cross reference that to the shared strings value
I have no mapped out all functions and xmls in the compressed file, but this is enough to get you started
It's only configured for columns A - Z, you'll have to write code for additional columsn
You need powershell 5.0 or later to have the native unzip feature
It assumes your first worksheet is named worksheet1
