Export all tags from the term store taxonomy in SharePoint Online

To extract all of the terms within a term store taxonomy use the following PowerShell script changing the fields to match your own tenancy details

[/csharp]

#Specify tenant admin and URL
$User = “username@domain.com”
$Password = Read-Host -Prompt “Please enter your password” -AsSecureString
$TenantURL = “https://tenant-admin.sharepoint.com”
$Site = “https://tenant-admin.sharepoint.com”

#Add references to SharePoint client assemblies and authenticate to Office 365 site – required for CSOM
Add-Type -Path “C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.dll”
Add-Type -Path “C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.Runtime.dll”
Add-Type -Path “C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.Taxonomy.dll”

#Bind to MMS
$Context = New-Object Microsoft.SharePoint.Client.ClientContext($Site)
$Creds = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($User,$Password)
$Context.Credentials = $Creds
$MMS = [Microsoft.SharePoint.Client.Taxonomy.TaxonomySession]::GetTaxonomySession($Context)
$Context.Load($MMS)
$Context.ExecuteQuery()

#Retrieve Term Stores
$TermStores = $MMS.TermStores
$Context.Load($TermStores)
$Context.ExecuteQuery()

#Bind to Term Store
$TermStore = $TermStores[0]
$Context.Load($TermStore)
$Context.ExecuteQuery()

#Retrieve Groups
$Groups = $TermStore.Groups
$Context.Load($Groups)
$Context.ExecuteQuery()

#Retrieve TermSets in each group
Foreach ($Group in $Groups)
{
$Context.Load($Group)
$Context.ExecuteQuery()
Write-Host “Group Name:” $Group.Name -ForegroundColor Green
$TermSets = $Group.TermSets
$Context.Load($TermSets)
$Context.ExecuteQuery()
Foreach ($TermSet in $TermSets)
{
Write-Host ” Term Set Name:”$TermSet.Name -ForegroundColor Yellow
Write-Host ” Terms:” -ForegroundColor DarkCyan
$Terms = $TermSet.Terms
$Context.Load($Terms)
$Context.ExecuteQuery()
Foreach ($Term in $Terms)
{
Write-Host ” ” $Term.Name -ForegroundColor White
Write-Output $Term.Name >> “C:\tags.csv”
