在没有 Office 的服务器上对 Excel 文件执行 PowerShell 操作（打开并使用密码另存为）

Question

我正在尝试执行与 Excel 文件一起运行的 PowerShell 脚本，该脚本会打开 excel 并使用密码保护对文件执行另存为操作。这在装有 Office 的 PC 上运行良好，但在未安装 Office 的服务器上运行不佳。

我知道有一些库可以使用，但我不知道如何使用它们，这里是 PowerShell 脚本的代码：

$excel = New-Object -ComObject Excel.Application
$excel.Visible = $true
$excel.DisplayAlerts = $false
$LoadPath = Join-Path -Path $pwd -ChildPath "TEMPLATE4WEEKS.xlsx"    #$pwd is your current working dir
$SavePath = Join-Path -Path $pwd -ChildPath "TEMPLATE4WEEKSprotected.xlsx"
$wb = $excel.Workbooks.Open($LoadPath)


$wb.SaveAs($SavePath,[Type]::Missing,"password")
$excel.Quit()

并且我已经阅读了一些有关库的内容，例如 EPPlus (https://archive.codeplex.com/?p=epplus)，但我不知道如何使用它。

如果值得一提，我在服务器上尝试执行 PowerShell 脚本时遇到的错误如下：

Answer 1

在这里综合我的多条评论作为答案：

下载 EPPlus：https://www.nuget.org/packages/EPPlus/
阅读一些文档并检查它们的示例代码： https://github.com/JanKallman/EPPlus/wiki/Getting-Started
然后像这样打开并保存文件：

.

Add-Type -Path D:\PathOfExile\epplus.4.5.3.2\lib\net40\EPPlus.dll
$ExcelPackage = New-Object OfficeOpenXml.ExcelPackage("C:\Metallica\WhereverIMayRoam\hehe.xlsx")
$ExcelPackage.Workbook.Worksheets.Add("Test")
$ExcelPackage.SaveAs("C:\Metallica\WhereverYOUMayRoam\newfile.xlsx", "hohoho") # This sets the password of the xlsx to hohoho
