在Powershell中打开受密码保护的Excel

问题描述

我正在尝试在Powershell中打开一个受密码保护的Excel工作表，并输出有关工作表中有多少行的报告.

I'm trying to open a password protected excel sheet in powershell and output a report on how many rows are in the sheet.

如果工作表不受密码保护，则脚本可以正常工作，但是如果设置了密码，我似乎无法获得强大的功能来打开它.

the script works absolutely fine if the sheet isn't password protected but I can't seem to get powershell to open it if there is a password set.

我当前的脚本是

$Report = "S:\Business Support\excel tests\MI Tool - Live.csv"
$path = "S:\Business Support\excel tests"
[Array]$Results = $null
$excelSheets = Get-Childitem -Path $path -Include "MI Tool - Live.xlsm" -Recurse
$excel = New-Object -comobject Excel.Application
$excel.visible = $false
$password = "blablabla"
$updatelinks = 0


foreach($excelSheet in $excelSheets)
{
 $workbook = $excel.Workbooks.Open($excelSheet,$updatelinks,$password)
 $rowCount = $null

  $worksheet = $workbook.sheets.item("Data")
  $rowMax = ($worksheet.usedRange.rows).count
  $rowCount += $rowMax

$Results += New-Object Psobject -Property @{
    "File Name"=$excelSheet.Name
    "Row Count"=$rowCount}
$excelSheet.Name
$workbook.Sheets.count
$rowCount
}
$excel.quit()
Stop-Process -Name EXCEL -Force
$Results | select "File Name","Row Count" | Export-Csv $Report -NoTypeInformation

这是我得到的错误:

Exception calling "Open" with "3" argument(s): "Open method of Workbooks class failed"
At line:3 char:35
+  $workbook = $excel.Workbooks.Open <<<< ($excelSheet,$updatelinks,$password)
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : ComMethodTargetInvocation

You cannot call a method on a null-valued expression.
At line:5 char:37
+   $worksheet = $workbook.sheets.item <<<< ("Data")
    + CategoryInfo          : InvalidOperation: (item:String) [], RuntimeException
    + FullyQualifiedErrorId : InvokeMethodOnNull

如果我删除$ password变量，它可以工作，但是我必须手动输入密码.

If I take out the $password variable it works but I then have to enter the password manually.

推荐答案

您的打开超载不正确.密码是第五个变量.看看MSDN来看看

Your Open overload is incorrect. The password is the 5th variable. Have a look at MSDN to see

所以我相信您需要先填充ReadOnly和Format.您必须填充这些值.

So you would need to populate ReadOnly and Format first I believe. You would have to populate those values.

$excel.Workbooks.open($path,0,0,5,$password)

请查看MSDN，以了解值在2,3和4位置所代表的含义.

Look at the MSDN to understand what the values represent in the 2,3 and 4 positions.
