Search for PowerBI Parameters

Search for PowerBI parameters with PowerShell

Thanks for bearing with me! First blog post of 2026, lets just say I have been busy! To start us off, I have another PowerShell script I put together the end of last year, a way to search for PowerBI parameters with PowerShell.

When running:

  • multiple workspaces
  • with multiple reports
  • all with multiple parameters

Sometimes, it seems you need an easy solution to find where you have set parameters to specific items.

My use case for example, I have a number of reports pointing to a specific data source. When migrating that data source I wanted to discover which reports where still attached so this script made it super simple!

How it works?

This PowerShell script, similar to a few of my others will loop through all the PowerBI workspaces you have access to, and at the same time loop through every report and parameter, logging where it finds the defined parameter as it goes.

The parameters endpoint for every dataset makes it simple to find this information and we can simply loop through each. It will naturally log results in a custom object showing the:

  • Workspace Name
  • Report Name
  • Parameter Name
  • Current Parameter Value
  • Dataset ID

What do you need to modify?

This is one is a real simple one, just change the searchValue to the actual value of the parameter itself you want to discover, for example

Parameter Name : Source

Parameter Value : SQLDB1

So in this case we search for SQLDB1

So hopefully this will help you! It certainly saved a huge amount of time for me! code below!

$SearchValue = "Domain"

$workspaces = Get-PowerBIWorkspace -All

$Results = $workspaces | ForEach-Object -Parallel {
    $Target = $using:SearchValue
    $workspace = $_
    
    try {
        # Get reports in this workspace
        $Reportlist = Get-PowerBIReport -WorkspaceId $workspace.Id
        
        foreach ($Report in $Reportlist) {
            if (-not $Report.DatasetId) { continue }

            $params = (ConvertFrom-Json $resp).value

            foreach ($p in $params) {
                if ($p.currentValue -eq $Target) {
