childishbambino You can use PnP PowerShell code like below to apply conditional formula to list fields: 

 

$conditionalFormula = "=if[{0}],'true','false')" -f '$myColumnB'
 
# Get SP list field
$field = Get-PnPField -List "Tasks" -Identity "ColumnA"
 
# Apply conditional formula to column
$field.ClientValidationFormula = $conditionalFormula
$field.Update()
Invoke-PnPQuery

 

Where ColumnA is the internal name of your SharePoint column. You can get the internal name of column using various methods shown in this article: How to find the Internal name of columns in SharePoint Online?

disregard, okay, now how do I acesss the sharepoint list that I want to make these chages on?

Import-Module -Name PnP.PowerShell -Debug -Force

Connect-PnPOnline -Url

$site =

$sharedDocumentsURL = $site+"/Shared Documents"

$sharedFiles = Get-PnPListItem -List "Shared Documents"

foreach ($file in $sharedFiles) {

Write-Host "File name: $($file["FileLeafRef"])"

}

I have this, but i do not care about the shared documents, I need to access the SPO list so I can use your code on it, how doI do this?

    dperez13 Use this code: 

     

    $siteUrl = "https://contoso.sharepoint.com/sites/siteName"
Connect-PnPOnline -Url $siteUrl -Interactive
  
$conditionalFormula = "=if[{0}],'true','false')" -f '$myColumnB'
 
# Get SP list field
$field = Get-PnPField -List "Tasks" -Identity "ColumnA"
 
# Apply conditional formula to column
$field.ClientValidationFormula = $conditionalFormula
$field.Update()
Invoke-PnPQuery

     

    Replace siteUrl variable value with URL of your SharePoint site and use display name of your list in place of Tasks (in above code).
