Get Input from CSV Files

Post by venkirocs » Fri Sep 06, 2019 6:37 am


For some bulk activities, I will get the input data through a CSV. I used a Button, when the button is clicked the OpenFileDialog will pop-up and capture the filename. Next I use the Import-Csv command to fetch the data from that file. Then will use the Foreach loop to process each object in the file.

Currently I have to hardcode the header of the csv file for the powershell commands to process the task.
e.g if the filename is rename.csv and the header consists of "Oldname" and "newname" as columns, i would code as below.

$data = Import-Csv -path C:\temp\rename.csv
foreach($pc in $data)
Rename-Computer -ComputerName $pc.Oldname -NewName $pc.newname -DomainCredential $cred

Because of this I have to insists the tool users to maintain the csv file and its headers. So for all the tools I create I would have to insists the users

is there a way to dynamically obtain the header of the csv, so the users can give any column header

$data[0] will give you the ordered col headers

To rename the columns in a CSV with columns:

import-csv test.csv -header oldname,newname | select * -skip 1
