PowerShell Scripts to Look for Excel files with .xls and .xlsx extensions - excel

Question

I have an already written scripts which looks for ONLY an excel file with .xls extension. Now,
I want the same scripts to look for either .xls or .xlsx which ever it finds in that particular location and use it......
The old scripts search for files in the F column only on the excel sheet/file.....This makes the search takes forever, so I would like it to search the files in the F column which ONLY have this path:root_project/Fut_DB_Projects in the E column of the excel sheet.
Pls let me know exactly where to insert it in the scripts. I'm very new to Powershell and your answers would be very much appreciated.

Try changing the first if to this
if($excelfile -ne $Null -and $excelfile -like "*.xls*" -and (Test-Path $excelfile) -eq $True)
