    I have multiple csvs in a folder that are name sequentially (e.g. 1 to 100). How is it possible to invoke multiple powershell child instances through PowerISE. Each of those child instances will read a corresponding csv and process it further. (e.g. instance 1 will invoke 1.csv likewise).

    Any way to achieve this?

    We do not deliver ready to use code on request. You will have to write it yourself.

    To make your life easier you should take a look at a module helping you dealing with runspaces in Powershell - PoshRSJob. You might watch the video from the maker of that module as well to get the idea ... Video: The Art of PowerShell Runspaces.

    No one would ever have a reason to do what you ask.  What you want to do is start multiple  PowerShell jobs or use a workflow.

    PowerShelISe is not an execution environment and cannot be used the way you ask.  It cannot automatically execute a script.  It is only a script editor and test environment.

    Before asking any question about PowerShell in this or any technical forum you will have to first learn basic PowerShell.

    Here is a good place to start: Microsoft Virtual   Academy - Getting Started with Microsoft PowerShell

    This will help you to understand why your question is a problem and how to use PowerShell to run jobs and script a workflow.

    Here is a basic example to help you get started:

    Get-ChildItem *.csv |
    ForEach-Object{
        [array]$jobs += Start-Job -ScriptBlock {<code to execute>} -ArgumentList $_
    }

    Do the tutorial to understand what this is and how it can be used.

    Here is a simple example of a workflow.

    Workflow ProcessCsvFiles{
    $files = Get-ChildItem *.csv
    foreach -parallel ($file in $files){
        # < proess the csv file >
    }
}
