PowerShell: Format second sheet within xlsx file - excel

Question

PowerShell: Format second sheet within xlsx file
I am working with an xlsx file that has two sheets within it.
I am uploading data into these sheets and formatting it.
I am able to successfully format the first sheet but not the second sheet.
This is the code for how I format the first sheet:
# Format Data: Autofit Columns
$lgTime = "[{0:HH:mm:ss}]" -f (Get-Date)
Write-Host "$lgTime Autofitting Data Columns..."
$range2autofit = $worksheet.UsedRange
$rowCount = $range2autofit.Rows.Count
[void] $range2autofit.EntireColumn.Autofit()
$lgTime = "[{0:HH:mm:ss}]" -f (Get-Date)
write-host "$lgTime Creating Excel Table Format ..."
$tableStyle = "TableStyleMedium9"
$tableStyle = "TableStyleLight21"
$Worksheet.Columns.Item("A").NumberFormat = "MM/DD/YYYY"
$ListObject = $WorkBook.ActiveSheet.ListObjects.Add(1, $range2autofit, $null , 1, $null, $tableStyle)
I would like the same formatting to be applied to the second sheet within the file but am having trouble doing that. I have tried using that same code again but with small changes such as:
Workbook.Worksheet.Item(2).UsedRange
Workbook.Worksheet.Item("Sheet2Name").UsedRange
My thought process is that I should be able to use the same code but just access the second sheet in it, I think I am just not accessing the second sheet correctly. That could be completely wrong though.
Edit:
This is where I defined $workbook and added a sheet to the xlsx file which is followed by the renaming of each sheet
$dataFile = "FILE LOCATION.xlsx"
$objExcel = New-Object -ComObject Excel.Application
$objExcel.Visible = $false
$workbook = $objExcel.Workbooks.Open($dataFile)
$worksheet = $workbook.Worksheets.Add()
$worksheetOne = $workbook.Worksheets.Item(1)
$worksheetOne.Name = "Sheet1Name"
$worksheetTwo = $workbook.Worksheets.Item(2)
$worksheetTwo.Name = "Sheet2Name"

From the code you added in your edit, it looks like you're getting tripped up when adding a sheet, then using the wrong index later? Worksheets.Add() creates a blank worksheet at index 2 by default, not at the end. For example:
# A good way to check and see what you're doing with your sheets:
$workbook.Worksheets | select Index,Name
Index Name
----- ----
1 Sheet1
2 Sheet2
# add a new sheet
$worksheet = $workbook.Worksheets.Add()
# check again
$workbook.Worksheets | select Index,Name
Index Name
----- ----
1 Sheet1
2 Sheet3 # whoops!
3 Sheet2
To add before/after a specific worksheet instead, you can specify like this:
# missing value is required for COM functions
$newSheet = $workbook.Worksheets.add(
[System.Reflection.Missing]::Value, ## before index n
$workbook.Worksheets.Item(2) ## after index n
)
Then just be careful when you select your sheets, and you should be good to go!
# Setting sheet properties by referring to variable
$ws1 = $workbook.Worksheets.Item(1)
$ws1.Name = "Sheet1Name"
$ws1.UsedRange.EntireColumn.AutoFit()
$ws2 = $workbook.Worksheets.Item(2)
$ws2.Name = "Sheet2Name"
$ws2.UsedRange.EntireColumn.AutoFit()
