Powershell Script to Display List of all Workflows or Export all the workflows names to CSV

  List all Workflows in a SiteCollection     

 We had business requirement to display a list of all workflows in a Site collection.There are different approaches to view list of workflows in a sitecollection for a list or document library.

Go to the document library or list under Library Settings/List Settings user can view   with

•  Sharepoint UI ,
• Powershell

If you have a collection with few document librarys or lists you can manually navigate to each document library or list and check for workflows in SharePoint UI 

Library Settings/List Settings -> Workflow Settings ->

You can see in the above there are no workflows associated with the list.

Using PowerShell, to  Export all the workflow in a site collection to  CSV

PowerShell script to find out list of all workflows in a site collection is the best way to find.

SharePoint has  a class  called "WorkflowAssociation : "  

contains members that return custom information about that 

workflow's a 's association with the specific list or content 

type.

Cls

function DisplayWorkflows()

{

   foreach($subwebs in $site.AllWebs )

   {

     $ls= $subwebs.Lists;

    foreach($lists in $ls )

    {

    $workflows= $lists.WorkflowAssociations;

    foreach($wf in $workflows)

    {
