You seem to imply that's not already the case (though many wish it wasn't)

vlookup pseudo-joins ahoy !

I'll point out that if you find yourself with a RDBMS-like situation in Excel I highly recommend using Excel 2013+ 'tables' feature which adds foreign keys and better pseudo-joins (in pivot tables) inside of Excel. Better than anything hacked together with VLOOKUP. (heck, I've even seen some people hack it together with only SUMIF)

I use tables all the time in Excel 2010, haven't had much experience with 2013. Is this something that is truly new in 2013?

I don't know, I have no experience with 2010 so I went with the lower bound I can guarantee as opposed to potentially giving harmful wrong information. Can't edit my comment now.
