Powershell Export to CSV from Excel Certain Range

Hi, i have the below code, that works.  Require to only pull out a certain range from the excel Document, IE B2:B20

Any one any ideas ?

$sExcelFile="\\pahitfs\it\Sys Admin Team\WindowsServerPatching\2016\WindowsPatching_Reference_2016.xlsx"
$sCSVFile="C:\Patching\Schedule\$wksname.csv"
#$SheetName = "WinA-Test_Thu"

# Get COM Object
$oExcel = New-Object -ComObject "Excel.Application"
# Hide overwrite warning
$oExcel.DisplayAlerts = $false 

# Should Excel be visible?
$oExcel.Visible = $false
# and open excel file
$oExcelDoc = $oExcel.Workbooks.Open($sExcelFile)

# Open Worksheet
#$oWorkSheet = $oExcelDoc.sheets.item($SheetName)
for ($counter = 7; $counter -le $oExcelDoc.Worksheets.count; $counter++) {
    $oWorksheet = $oExcelDoc.Worksheets.item($counter)
    #Get Sheet Name
    $wksname = $oworksheet.name
    # Activate, show it
    $oWorksheet.Activate()
    $sCSVFile="C:\Patching\Schedule\$wksname.csv"
    $oWorksheet.SaveAs($sCSVFile,[Microsoft.Office.Interop.Excel.XlFileFormat]::xlCSVWindows)
}
$oExcelDoc.Close($false)
Start-Sleep 1
# Cleanup COM
[System.Runtime.InteropServices.Marshal]::ReleaseComObject($oWorksheet)|out-null
$oWorksheet=$null
Start-Sleep 1
# Cleanup COM
[System.Runtime.InteropServices.Marshal]::ReleaseComObject($oExcelDoc)|out-null
$oExcelDoc=$null
# Close Excel
$oExcel.Quit()
Start-Sleep 1
# Cleanup COM
[System.Runtime.InteropServices.Marshal]::ReleaseComObject($oExcel)|out-null
$oExcel=$null
[GC]::Collect()
[GC]::WaitForPendingFinalizers()

Since Excel does not allow to save a range, there are two possible approaches:
1. copy the range to a new sheet, and export that
2. use PowerShell to read the range and export it.

Which ever would be quicker

Is this a single column (B) only?

Yeah would be after the range for B

Replace line 24 with
    $oWorksheet.Range("B2:B20") | select Value2 | export-csv -NoType $sCSVFile

Hi,
is it the same range on all sheets?

Afaik there is no direkt method to export/save a range - you always have to copy the range to a new sheet and exporting that one.

Thanks.

Many thanks this works, although it is giving a header name of value2
Qlemo"Batchelor", Developer and EE Topic AdvisorCommented:
Do you need it different? This will create a column 'Your Column Name here' instead:
    $oWorksheet.Range("B2:B20") | select @{n='Your Column Name here'; e={$_.Value2}} | export-csv -NoType $sCSVFile

The data already contains the name on line1, so taking that name, so first line it takes is server name, at the moment it outputs
value2
server name
1
2
3

Would like

Server Name
1
2
3

Etc
Qlemo"Batchelor", Developer and EE Topic AdvisorCommented:
You could exclude that row from the range, by using "B3:B20", and then name the column in the script as shown.
Or we just dump the results as text instead of csv:
    $oWorksheet.Range("B2:B20") | select -Expand value2 | Out-File $sCSVFile
