使用power shell

Question

在一个文件夹中，我有大约20个excel工作簿，每个工作簿都有MIS for upload excel表我希望使用powershell将来自MIS的每个工作簿的所有数据合并到上传excel表到新的csv文件

下面是我试过的代码。但我想要浏览文件夹方法。

＆＃13;

＆＃13;

#Get a list of files to copy from
$Files = GCI 'C:\Users\r.shishodia\Desktop\May 2018' | ?{$_.Extension -Match "xlsx?"} | select -ExpandProperty FullName

#Launch Excel, and make it do as its told (supress confirmations)
$Excel = New-Object -ComObject Excel.Application
$Excel.Visible = $True
$Excel.DisplayAlerts = $False

#Open up a new workbook
$Dest = $Excel.Workbooks.Add()

#Loop through files, opening each, selecting the Used range, and only grabbing the first 6 columns of it. Then find next available row on the destination worksheet and paste the data
ForEach($File in $Files[0..20]){
    $Source = $Excel.Workbooks.Open($File,$true,$true)
    If(($Dest.ActiveSheet.UsedRange.Count -eq 1) -and ([String]::IsNullOrEmpty($Dest.ActiveSheet.Range("A1").Value2))){ #If there is only 1 used cell and it is blank select A1
        $Source.WorkSheets.item("MIS for Upload").Activate()
        [void]$source.ActiveSheet.Range("A1","R$(($Source.ActiveSheet.UsedRange.Rows|Select -Last 1).Row)").Copy()
        [void]$Dest.Activate()
        [void]$Dest.ActiveSheet.Range("A1").Select()
        }Else{ #If there is data go to the next empty row and select Column A
        $Source.WorkSheets.item("MIS for Upload").Activate()
        [void]$source.ActiveSheet.Range("A2","R$(($Source.ActiveSheet.UsedRange.Rows|Select -Last 1).Row)").Copy()
        [void]$Dest.Activate()
        [void]$Dest.ActiveSheet.Range("A$(($Dest.ActiveSheet.UsedRange.Rows|Select -last 1).row+1)").Select()
    }
    [void]$Dest.ActiveSheet.Paste()
    $Source.Close()
}
$Dest.SaveAs("C:\Users\r.shishodia\Desktop\Book2.xlsx",51)
$Dest.close()
$Excel.Quit()

Answer 1

为此，您可以使用ImportExcel module - repo README中包含的安装指南。

安装此模块后，您可以轻松使用Import-Excel cmdlet，如下所示：

$Files = GCI 'C:\Users\r.shishodia\Desktop\May 2018' | ?{$_.Extension -Match "xlsx?"} | select -ExpandProperty FullName
$Temp = @()
ForEach ($File in $Files[0..20]) { # or 19 if you want to have exactly 20 files imported
  $Temp += Import-Excel -Path $File -WorksheetName 'MIS for Upload' `
  | Select Property0, Property1, Property2, Property3, Property4, Property5
}

要导出（您编写了CSV，但目标文件格式为xlsx）：

$Temp | Export-Excel 'C:\Users\r.shishodia\Desktop\Book2.xlsx'

或

$Temp | Export-Csv 'C:\Users\r.shishodia\Desktop\Book2.csv'
