Powershell: Error while calling the SaveAs Method of some Office Applications

1 Comment

Hi,

if you tried to save a word or excel document as another format you got an error. For example, if you want to convert a CSV File to a Excel workbook and save it in Excel 95/97/2003 format.

[reflection.assembly]::LoadWithPartialName("Microsoft.Office.InterOp.Excel")
$oExcel = New-Object -ComObject "Excel.Application"
$sCSVFile="D:\temp\ImportFile.csv"
$oExcel.Visible = $true
$oCSVWorkbook=$oExcel.Workbooks.Add()
$oExcel.Workbooks.OpenText($sCSVFile)
$oCSVWorkbook.SaveAs("D:\temp\test.xls",[Microsoft.Office.Interop.Excel.XlFileFormat]::xlExcel9795)
Exception calling "SaveAs" with "1" argument(s): "SaveAs method of Workbook class failed"
At D:\test\CSV2Excel.ps1:29 char:20
+ $xl_workbook.SaveAs <<<< ("D:\Temp\test.xls")
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : ComMethodTargetInvocation
