Question

I have csv file containing all the Global term set values of SharePoint 2013 taxonomy. I want to import that in SharePoint Online using powershell script. Please suggest if any powershell script is there for importing CSV file.

Answer 1

We can use PnP PowerShell command Import-PnPTermSet to achieve it.

Or we can also use CSOM with PowerShell to achieve it.

#Load SharePoint CSOM Assemblies
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
Add-Type -Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Taxonomy.dll"

#Variables for Processing
$AdminURL = "https://tenant-admin.sharepoint.com/"
$TermGroupName= "People"
$TermSetName="Job Title"
$CSVFile ="C:\Temp\ImportTerms.csv"
$TermHeaderInCSV ="JobTitle"

Try {
    #Get Credentials to connect
    $Cred = Get-Credential
    $Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Cred.Username, $Cred.Password)

    #Setup the context
    $Ctx = New-Object Microsoft.SharePoint.Client.ClientContext($AdminURL)
    $Ctx.Credentials = $Credentials

    #Get the term store
    $TaxonomySession=[Microsoft.SharePoint.Client.Taxonomy.TaxonomySession]::GetTaxonomySession($Ctx)
    $TaxonomySession.UpdateCache()
    $TermStore =$TaxonomySession.GetDefaultSiteCollectionTermStore()
    $Ctx.Load($TaxonomySession)
    $Ctx.Load($TermStore)
    $Ctx.ExecuteQuery()

    #Get Termstore data from CSV and iterate through each row
    Import-Csv $CSVFile | ForEach-Object {

        #Get the Term Group
        $TermGroup=$TermStore.Groups.GetByName($TermGroupName)

        #Get the term set
        $TermSet = $TermGroup.TermSets.GetByName($TermSetName)

        #CSV File Header Row in Term to Add
        $TermName = $_.$($TermHeaderInCSV)

        #Check if the given term exists already
        $Terms = $TermSet.Terms
        $Ctx.Load($Terms)
        $Ctx.ExecuteQuery()
        $Term = $Terms | Where-Object {$_.Name -eq $TermName}

        If(-not $Term)
        {
            #Create Term Set
            Write-host "Creating Term '$TermName'" -ForegroundColor Cyan
            $Term = $TermSet.CreateTerm($TermName,1033,[System.Guid]::NewGuid().toString())
            $Ctx.Load($Term)
            $Ctx.ExecuteQuery()
            $Term.TermStore.CommitAll()
            $TaxonomySession.UpdateCache()
            Write-host "New Term '$TermName' Added Successfully!" -ForegroundColor Green
        }
        else
        {
            Write-host "Term '$TermName' Exists Already!" -ForegroundColor Yellow
        }
    }
 }
Catch {
    write-host -f Red "Error Importing Term store Data!" $_.Exception.Message
}
