Pivot tables in 90 seconds

I first started evangelising about Excel pivot tables on AccountingWEB back in 1999 - seems like a lifetime.

That was in print - a self-teach tutorial.  Here's a more up-to-date method - a video showing sales analysis via pivot tables.

It's a bit amateurish and I put it on Youtube in default of anywhere else;  but if you've never seen pivot tables before, this will give you the basic idea in a minute and a half.

This second video gives the same sales analysis demo.   But it's at a more leisurely pace so you can see how it's done.
