Trying to replace value of a variable via powershell-CodePudding

I am trying to replace the value of a variable in parameters file using Replace(). This file which I am trying to edit accepts json format. But I am unable to do so. I am using this below script to do so. This only print the name of that particular field for which I am trying to replace a numeric value.

I tried this but it just displays the name of the variable which contains the old value I am trying to edit/replace.

if($Value -like "*xyz*")
    {
      $Value -replace '$OldValue', '$NewValue'
    }
else
   {
     Write-Host "$OldValue"
   }

Please provide a solution so that I can replace a numeric value of a particular variable for json file.

Good day Tanya

You should be able to use this:

if ($value -like *xyz*) {
   $value.replace($oldValue,$newValue)
} else {
   Write-Host $oldValue

Have a nice day
