Hi, for my academic research database I’m trying to write a formula that will automatically extract a four-digit number from a cell (i.e. extracting year from a citekey).
For example (Citekey --> Year),
Downs1965NonmarketDecisionMaking --> 1965
Welborn1968BureaucracyAnthonyDowns --> 1968
Any ideas on how I might be able to do this? Thanks.

If those are the ONLY numeric digits within your entire text string, then you could do it with this formula:
VALUE(Citekey)
Hope this helps! If this answers your question, could you please mark this comment as the solution to your question? This will help other people who have a similar question.

It works perfectly well except for cells with a period (see screenshot below). Is there a way to make the value() formula work?

If you have periods, then use this formula:
VALUE(SUBSTITUTE(Citekey,".",""))
