Delete InfoPath Published Columns or Hidden Columns

Some of you may have encountered the problem of deleting the InfoPath published columns. These columns are actually published as Content Types, so better we call them as content types. A custom column is easy to delete using OOB feature but deleting an InfoPath published column is pain in the arse. Below is a small script that will help you delete the InfoPath published columns.

Note: The below PowerShell Script can be use to delete any type of column - custom, InfoPath, or hidden

function Delete-WorkflowColumn ($webURL, $listName, $columnName)
    {
        #Setup variables from the user input
        $web = Get-SPWeb $webURL
        $list = $web.Lists[$listName]
        $column = $list.Fields[$columnName]
       
        #Make sure the column is not hidden or read only
        $column.Hidden = $false
        $column.ReadOnlyField = $false
        $column.Update()

        #Delete column and dispose of the web object
        $list.Fields.Delete($column)
        write-host "Deleted column"
        $web.Dispose()
    } //Press Enter

Delete-WorkflowColumn -webURL http://pro1:4444/sites/test -listName "EmpList" 

-columnName "EmpAddress"

//Press Enter

That's All... You are Done !!!
