Here is me helping you write the script: study the VBScript and/or PowerShell script at the SuperUser question you linked. Tweak it, and see how those changes affect the results. Experiment until it no longer requires the quote marks. Continue experimenting until it does everything you want it to. If you have shown some effort, but still cannot get it to work, ask a question in an appropriate forum, where the topic is about the scripting language you are using (SuperUser/StackOverflow might be a good location).

Some here would be able to use the PythonScript plugin to automate those calculations inside Notepad++. Others might suggest skipping the middle-man: if you have a file with 14000 instances, it might be simpler to run it through an offline script, which could be written in VBA, Python, Lua, Perl, or your favorite scripting language. But it might take a few hours to write something: and that brings me to my last point:

But if by “help me to write a script” you mean, “write a script for me”, then you’ve come to the wrong place. It sounds like you’re asking for custom coding services, which will likely cost you something. Good luck in presenting the question, as framed (ie, without showing any effort of your own), in any coding forum and getting the exact script you want.
