Why is my code not saving the correct worksheet? - excel

Question

I have this following Powershell script to convert the 2nd sheet on a XLSB file to CSV.
Function XLSBtoCSV ($Path)
{
foreach($File in (Get-childItem $Path -Filter "*.xlsb"))
{
$pwd = $Path
$excelFile = "$pwd\" + $File
$Excel = New-Object -ComObject Excel.Application
$Excel.Visible = $false
$Excel.DisplayAlerts = $false
$wb = $Excel.Workbooks.Open($excelFile)
$ws = $wb.Worksheets.item(2)
$ws.SaveAs("$pwd\" + $File.BaseName + "-" + $ws.name + ".csv", 6)
$Excel.Quit()
}
}
$FilePath = Get-Location
XLSBtoCSV -Path $FilePath
This script used to work but somehow now it only saves the last worksheet (sheet 3). I have tried to change to different sheet number but every time, the last worksheet is saved.

Very close. You need to loop through the worksheet items instead of just calling items(2) as covered in another answer:
Function XLSBtoCSV ($Path)
{
foreach($File in (Get-childItem $Path -Filter "*.xlsb"))
{
$pwd = $Path
$excelFile = "$pwd\" + $File
try{
$Excel = New-Object -ComObject Excel.Application
$Excel.Visible = $false
$Excel.DisplayAlerts = $false
$wb = $Excel.Workbooks.Open($excelFile)
# source https://stackoverflow.com/questions/16156951/how-to-iterate-through-excel-worksheets-only-extracting-data-from-specific-colum
foreach($ws in $wb.Worksheets)
{
$ws.SaveAs("$pwd\" + $File.BaseName + "-" + $ws.name + ".csv", 6)
}
}
finally
{
# close/dispose all the open parts of Excel
if($Excel)
{
$Excel.Quit()
}
}
}
}
$FilePath = Get-Location
XLSBtoCSV -Path $FilePath
