Replace Multiple words in MSWord using Powershell - powershell

Question

I am trying to use powershell to replace multiple lines in a word document without having to save and close after every change. right now I have:
$objWord = New-Object -comobject Word.Application
function findAndReplace
{
$objDoc = $objWord.Documents.Open("C:\temp\test.docx")
$objWord.Visible = $false
$objSelection = $objWord.Selection
$a = $objSelection.Find.Execute($FindText, $false, $true, $False, $False, $False, $true, 1, $False, $ReplaceWith)
$objDoc.Save()
$objDoc.close()
}
############DEVICE DETAILS#############
$FindText = "USERID"
$ReplaceWith = $AssociateIDnum
findAndReplace
$FindText = "CONTACTNUMBER"
$ReplaceWith = $Phone
findAndReplace
Using this, I made the function that runs those commands, and I change the $findtext and $replacetext on each instance of a new word, then run the function each time.
With this method, the Word Doc opens and closes nearly 25 times to write each new word replacement.
Is there a way I can make a function or loop to make it change the $findtext
and $replacewith variable each time?
I am relatively new to powershell but I have been learning some of it on my own.

Try using a list of objects as a parameter to the function, something like that :
$objWord = New-Object -comobject Word.Application
function findAndReplace ($todoObjs)
{
$objDoc = $objWord.Documents.Open("C:\temp\test.docx")
$objWord.Visible = $false
$objSelection = $objWord.Selection
foreach ($todoObj in $todoObjs)
{
$a = $objSelection.Find.Execute($($todoObj.FIND), $false, $true, $False, $False, $False, $true, 1, $False, $($todoObj.REPLACE))
}
$objDoc.Save()
$objDoc.close()
}

$todo = #"

$todoObjs = ConvertFrom-Csv $todo
findAndReplace $todoObjs
