CSV Not Exporting after merge - excel

Question

I asked a similar question here and it got me on a very good track, however while trying to 'all in one' it, I ended up with an issue. I'm very close, but after testing numerous theories I'm starting to reverse what I need.
I have a multiple sheet Excel - I need to pull the first sheet, CSV-ify it, then remove the headers, then only get the first 3 digits from the first line.("List Name")
My PS is:
#Create and get my Excel Obj
$excel = New-Object -comobject Excel.Application
$excel.visible=$false
$excel.DisplayAlerts=$false
$UserWorkBook = $excel.Workbooks.Open("C:\path\to\file\CompleteTest.xls")
$UserWorksheet = $UserWorkBook.Worksheets.Item(1)
$hitlistCSV = "C:\path\to\file\BroadcastReport.csv"
$xlCSV = 6 #changed-grav
#Save, close, and clean up
$UserWorksheet.SaveAs($hitlistCSV,$xlCSV)
$UserWorkBook.close()
$excel.quit()
$excel = $null
$expandfile = "C:\path\to\file\BroadcastReport.csv"
(gc $expandfile | select -Skip 1) | sc $expandfile
Import-Csv $expandfile | ForEach-Object {
$_."List Name" = $_."List Name".SubString(0,3)
$_
}
$expandfile | Export-Csv "C:\path\to\file\BroadcastReport.csv" -NoTypeInformation
I've modified it a lot, and tried to make it single runnable to avoid schedule multiple BATs. Everything seems to work - It pulls the first sheet, renames it, and replaces the top line EVERY time I run the 2nd portion. However, the SubString portion isn't taking effect, nor am I getting a 'FileExport' file.
My last modification now makes it so everytime it replies that I need to 'supply an Input Object' so I feel like it has to do with function-izing it. For reference the line I need to split is double quoted because it has commas. Ex:
"123|ST,City"
I only need the 123. When I just import the file and run my ForEach function, the output is what I expect. Just saving it to the file isn't.
Thanks.
Welcome any input.
XLS Source
This is the header line I need to skip
List Name Broadcast Name ColumC ColumD Colum E ColumF Colum G ColumJ
401|ST, City ST, City - More Text(LSM) (16803) 1 854 73 854 233 27.28%
402|ST, City ST, City - October (LSM) (16807) 1 851 57 851 186 21.86%
CSV Source after XLS -> CSV
One thing that is weird is that once it becomes a CSV, I'm left with ~6 fields of just commas. Example:
List Name,Broadcast Name,ColumC,ColumD,Colum E ,Colum,Colum F,ColumG,,,,,,
"402|ST,City","ST, City - More Text(ACR) (16803)",1,854,73,854,233,27.28%,,,,,,
"402|ST,City","City, ST - Text (LSM) (16807)",1,851,57,851,186,21.86%,,,,,,
UPDATE:
Added example, updated source - Column names keep a space where a space exists.
Broadcast Name column -does- have a comma in it, but I assume it's being exported with double quotes.

#Create and get my Excel Obj
$excel = New-Object -comobject Excel.Application
$excel.visible=$false
$excel.DisplayAlerts=$false
$UserWorkBook = $excel.Workbooks.Open("C:\path\to\file\ExcelBook.xls")
$UserWorksheet = $UserWorkBook.Worksheets.Item(1)
$hitlistCSV = "C:\path\to\file\Output.csv"
$xlCSV = 6 #changed-grav
#Save, close, and clean up
$UserWorksheet.SaveAs($hitlistCSV,$xlCSV)
$UserWorkBook.close()
$excel.quit()
$excel = $null
$expandfile = "C:\path\to\file\Output.csv"
$report = get-content $ExpandFile | select -skip 1 | convertfrom-csv | ForEach-Object {
$_."List Name" = $_."List Name".SubString(0,3)
$_
}
$report | Export-Csv ""C:\path\to\file\Output.csv" -force -NoTypeInformation
Issue was a slight modification to the export function being separated functions. I assume due to some sort of write lock.

The problem is on your last line, you are setting $expandfile to the return result of export-csv, it is prompting you to provide an input because it is trying to perform the export but is only provided with a path. Just change the last line to
$expandfile | Export-Csv "C:\Users\Donavin\Desktop\TXRH\FileExport.csv" -NoTypeInformation
EDIT
Ok need to make a few more changes for things to work correctly, valid import/export code is below
$expandfile = "C:\path\to\file\BroadcastReport.csv"
(gc $expandfile | select -Skip 1) | sc $expandfile
Import-Csv $expandfile | ForEach-Object {
$_."List Name" = $_."List Name".SubString(0,3)
$_
} | Export-Csv "C:\path\to\file\BroadcastReport.csv" -force -NoTypeInformation
