PowerShell Adding "-" between every third char in string

Question

Hello I'm new with PowerShell. I have a string that I'm trying to add an "-" between every third char.

00255D413701 -> 00-25-5D-41-37-01

Anyone has an idea how to do this the easiest way?

Answer 1

(?<=\G.{2})(?!$) might do the trick using regex and -replace:

'00255D413701' -replace '(?<=\G.{2})(?!$)', '-'
