powershell XLS to CSV conversion issue

Question

Я запускаю код ниже, чтобы конвертировать XLS в CSV, но получаю странную ошибку. Может ли кто-нибудь указать мне в правильном направлении, что может быть причиной этой проблемы? Я использую powershell v3.0. не знаю, чего я здесь не вижу.

PARAM 
    (
     [parameter(Mandatory = $true)] 
     [string] 
     $excelFilePath = $(throw "Must give a valid Excel (*.xls) file path.") 
     , 

     [parameter(Mandatory = $true)] 
     [int] 
     $leadingRowsToDelete = $(throw "Must specify how many leading rows to delete.") 
     , 

     [parameter(Mandatory = $false)] 
     [string] 
     $csvFilePath = $null 
     , 

     [parameter(Mandatory = $false)] 
     [int] 
     $xlCSV = 6 
    ) 


    if(! $csvFilePath) 
    { 
     $csvFilePath = $excelFilePath -replace ".xls$", ".csv" 
    } 

    $Excel = New-Object -Com Excel.Application -Property @{Visible = $false} 
    $Excel.displayalerts=$False 

    $WorkBook = $Excel.Workbooks.Open($excelFilePath) # Open the file 
    $Sheet = $WorkBook.Sheets.Item(1) # Activate the first worksheet 

    # Delete the first $leadingRowsToDelete rows 
    for($i = 1; $i -le $leadingRowsToDelete; $i ++) 
    { 
     [void]$Sheet.Cells.Item(1, 1).EntireRow.Delete() # Delete the first row 
    } 

    $WorkBook.SaveAs($csvFilePath, $xlCSV) 

    $Excel.quit() 

тзд Ошибки, я получаю это:

Answer 1

Согласно комментариям Op, в вопросе был вызван неисправными разрешениями на файл целевой Excel.

Скрипт отлично работает в локальном файле с полными разрешениями.
