How can I use PowerShell to `save as…` a different file extension?

Question

I\'m using the following powershell script to open a few thousand HTML files and \"save as...\" Word documents.

param([string]$htmpath,[string]$docpath = $d

I was having problems just converting the filename from .html to .docx. I took your code above and changed it to this:

function Convert-HTMLtoDocx {
    param([string]$htmpath)
    $srcfiles = Get-ChildItem $htmPath -filter "*.htm*"
    $saveFormat = [Microsoft.Office.Interop.Word.WdSaveFormat]::wdFormatXMLDocument
    $word = new-object -comobject word.application
    $word.Visible = $False

    ForEach ($doc in $srcfiles) {
        Write-Host "Processing :" $doc.fullname
        $name = Join-Path -Path $doc.DirectoryName -ChildPath $($doc.BaseName + ".docx")
        $opendoc = $word.documents.open($doc.FullName)
        $opendoc.saveas([ref]$name.Value,[ref]$saveFormat)
        $opendoc.close()
        $doc = $null
    }  #End ForEach

    $word.quit()
} #End Function

The problem was the save format. For whatever reason, so save a document as a .docx you need to specify the format at wdFormatXMLDocument not wdFormatDocument.
