Pivot tables in Excel. Manager came to me and showed me this spreadsheet he spent 2 weeks making. ( he was very proud ). I asked why he didn’t use a pivot table. He’d never heard of them. 60 seconds later I had recreated his report from scratch. I’m a programmer and I still use them to try out ideas before going to code.
