I'm exporting an AD report via power shell using the code below. 

`$Get-ADUser -Filter 'enabled -eq $true' -SearchBase "OU=Staff,OU=Users,OU=OSA,DC=domian,DC=org" -properties mail, employeeID | select employeeID, mail, ObjectGUID | Export-CSV "C:\Reports\ADExports\Students.csv" -notypeinformation`

It outputs the csv file and everything looks fine except, the 'Data type' of all columns are set to 'Short Text'. 

I require the Employee ID column type to be 'Numbers'. Is it possible to export a csv with custom field type. 

I hope this make sense. 

Thanks in advance.
