A script that pulls the year a domain was registered

I have a list of 1 million domains in an Excel spreadsheet and I need to know the year each domain was registered.

I would like you to write a script that looks up each site in the Wayback Machine and pulls the year the first copy was archived. Or, if you can come up with a better way, tell me how you would do it.

What I want to end up with is a domain age column in my spreadsheet so I can see the year each domain was registered.

Any queries, please let me know.
