powershell excel get first row(header) column count - excel

Question

I'm trying to count the cell number of the first row (A1-D1) which is known as header and get that count as the counter.
As all the while find most of them using Usedrange to count the columns:
$headercolcount=($worksheet.UsedRange.Columns).count
But UsedRange will capture maximum count in the whole activesheet, which resulting not identical to the column count in first row if there is extra content data below the header.
I only wish to grab just the first row:
[]
Update:
For clearer view, here is an example.
As 1F & 1G there are no value present, so the answer should be 5 as 1A-1E as it contains data. So how should I grab the 5 correctly?

Get-Process excel | Stop-Process -Force
# Specify the path to the Excel file and the WorkSheet Name
$FilePath = "C:\temp\A_A.xlsx"
$SheetName = "Blad1" # In english this is probably Sheet1
# Create an Object Excel.Application using Com interface
$objExcel = New-Object -ComObject Excel.Application
# Disable the 'visible' property so the document won't open in excel
$objExcel.Visible = $false
$objExcel.DisplayAlerts = $false
# Open Excel file and in $WorkBook
$WorkBook = $objExcel.Workbooks.Open($FilePath)
# Load WorkSheet 'Blad 1' in variable Worksheet
$WorkSheet = $WorkBook.sheets.item($SheetName)
$xlup = -4162
$lastRow = $WorkSheet.cells.Range("A1048576").End($xlup).row
# get the highest amount of columns
$colMax = ($WorkSheet.UsedRange.Columns).count
# initiatie a counter
$count = $null
# set the column you'd like to count
$row = 1
for ($i = 0; $i -le $colMax; $i++){
if($worksheet.rows.Item("$row").columns.Item($i+1).text){
$count++
}
}
$count
This should work. It takes the highest amount of columns. It then loops until it reaches that amount. During the loop it checks if the cell on that row is filled or not, if it is, it adds to the counter.
If you have millions of lines, this might not be the best way but this works for me.
I've testes it with an excel file:
With
$row = 1 this will give : 5
$row = 2 this will give : 6
$row = 3 this will give : 7
$row = 4 this will give : 8

$WorkSheet = $WorkBook.sheets.item($SheetName)
$xlup = -4162
$lastRow = $WorkSheet.cells.Range("A1048576").End($xlup).row
$amountofcolumns = $worksheet.UsedRange.Rows(1).Columns.Count
#OUTPUT
write-host "Last Used row:" $lastRow
Write-host "Amount of columns" $amountofcolumns
#show all columnnames
for($i = 1 ; $i -le $amountofcolumns; $i++){
$worksheet.Cells.Item(1,$i).text
}
This will show you how many rows you have AND will show you all values in the first row , ergo your titles.
