Powershell 获取Excel, Worksheet返回DataTable

注意：此脚本只能运行于32位Powersehll(x86)

建议本篇所有代码写于并保存于一个文件夹下

首先打开Powersehll_ISE(x86)

写入如下代码并保存：

Import-Module .\ACE.PSM1

$ds = Get-ACEData ".\附件二.RT-XXX control list for XXX.v3.Ex import and more att_20190428.xlsx" -Table "control list$"
$dt = $ds.tables[0]
#$drs = $dt.Select("[Calenda Date] is not null")
Write-Host $dt.Columns[0].ColumnName
Write-Host $dt.Rows[0][0];
$dt.Rows[0].ItemArray[0].ToString();
$dt.Rows[0].ItemArray[1].ToString();
$dt.Rows[0].ItemArray[2].ToString();

Import-Module .\ACE.PSM1 和 $ds = Get-ACEData ".\附件二.RT-RPA control list for FSA.v3.Ex import and more att_20190428.xlsx" -Table "control list$" 因为都是导入相对路径，也可以写入绝对路径， -Table "control list$" 是EXCEL的Sheet名字，后面需要加"$"

保存为test.ps1

然后再新建一个Powershell 文件,写入如下代码并保存为ACE.PSM1:

{
    param($ConnectionString)
 
    $conn = new-object System.Data.OleDb.OleDbConnection($ConnectionString)

.SYNOPSIS
Queries Excel and Access files.
.DESCRIPTION
Get-ACEData gets data from Microsoft Office Access (*.mdb and *.accdb) files and Microsoft Office Excel (*.xls, *.xlsx, and *.xlsb) files
.INPUTS
None
    You cannot pipe objects to Get-ACEData
.OUTPUTS
   System.Data.DataSet
.EXAMPLE
Get-ACEData -FilePath ./budget.xlsx -WorkSheet 'FY2010$','FY2011$'
This example gets data for the worksheets FY2010 and FY2011 from the Excel file
.EXAMPLE

Export-ModuleMember -function Get-ACEData

这是一个外置脚本，我们引用就好。

最后一步：

在ISE下面的运行命令窗口cd到你存放的路径：

因为我保存在C:\Users\jtang20\Desktop\test_ACE，所以我cd到这里啦

在test.ps1按F5运行，可以发现如下结果：

当然，你也可以换一下EXCEL文件名，和EXCEL WORKSHEET名字试一试，这边有赖人链接（有以上所有FILE）：
