Powershell script for Excel error code - excel

Question

I'm trying to convert an Excel .xls file that has several worksheets into a .csv with Powershell 4.0. I know the SaveAs in the for each loop isn't phrased right, and that the error is pointing to line 17 and character 9, I just don't know how to fix it or how to interpret the error code 0x800A03EC.
Here's the script:
Function ExportWSToCSV ($inputWorkbookPath, $outputFilePrefix, $outputDirectory)
{
#Start Excel invisibly without pop-up alerts.
$inputWorkbookPath = "R:\Unclaimed Property\NC State\Jun 2015\" + `
"NC_RAW_JUL1986thruMAR2013" + ".xls"
$excel = New-Object -ComObject Excel.Application
$excel.Visible = $false
$excel.DisplayAlerts = $false
#Open Excel file.
$workBook = $excel.Workbooks.Open($inputWorkbookPath)
foreach ($workSheet in $workBook.Worksheets)
{
$n = $inputWorkbookPath + "_" + $workSheet.Name
$workSheet.SaveAs($outputDirectory + $n + ".csv", 6)
}
$excel.Quit()
}
ExportWSToCSV -inputWorkbookPath "R:\Unclaimed Property\NC State\Jun 2015\NC_RAW_JUL1986thruMAR2013.xls" `
-outputFilePrefix "output_" `
-outputDirectory "R:\Unclaimed Property\NC State\Jun 2015\"
Here's the error:
Exception calling "SaveAs" with "2" argument(s): "Exception from HRESULT: 0x800A03EC"
At \\ncdfs1\documents$\ANDREWN\My Documents\PSscript_for_NC.ps1:17 char:9

I strongly feel your issue is coming from your path concatenation logic. Lets look at the following code from within your loop.
$n = $inputWorkbookPath + "_" + $workSheet.Name
$workSheet.SaveAs($outputDirectory + $n + ".csv", 6)
In your example call your variables I think are mapped as follows:
$inputWorkbookPath equals "R:\Unclaimed Property\NC State\Jun 2015\NC_RAW_JUL1986thruMAR2013.xls"
$workSheet.Name equals "Bagel" # I made that up.
$outputDirectory equals "R:\Unclaimed Property\NC State\Jun 2015\"
So you are going to try and set the new file name as:
R:\Unclaimed Property\NC State\Jun 2015\R:\Unclaimed Property\NC State\Jun 2015\NC_RAW_JUL1986thruMAR2013.xls_Bagel.csv
Which does not look right at all. If you just had the line in your loop
$outputDirectory + $n + ".csv"
I think you would see the issue. Just some simple debugging.
Lets fix this
First guess is that you just need to change it to something like this
$path = $outputDirectory + $workSheet.Name + ".csv"
$workSheet.SaveAs($path, 6)
Outside the scope of this question it would be a good idea to check if that path exists before saving it. It would save some potential headache.
