Adding data from one CSV file to another - equivalent to VLOOKUP etc

I don't think you really need to go the Regex route here. Using Where-Object should be enough, and simpler imo. Also, and this is personal preference, but I never like relying on an external counter to manage accessing array objects when I can avoid it. Try the below and see how that works for you. Feel free to shorten the variable names, I was just being descriptive for clarity.

ForEach($Entry in $Addresses)
    {
    $PhoneNumbersLineObj = $PhoneNumbers | Where-Object {$_.Name -like "$($Entry.Name)"}
    $Entry.PhoneNumber = $PhoneNumbersLineObj.PhoneNumber
    }

How to Replace Characters, Text, and Strings in Excel
August 30, 2024 - Both of them replace one or more characters in a text string with another text string. The difference lies in how the first string is identified. REPLACE selects the first string based on the position. So you might replace four characters, starting with the sixth character in the string. SUBSTITUTE selects based on whether the string matches a predefined search. You might tell Excel to replace any instance of โ€œFAโ€ with โ€œLUโ€ for example.
