title: how to turn off auto-something (but seemingly not auto-complete or auto-correct) in excel 2010
body: <p>if I type "MAR3011" into a cell in Excel, Excel unhelpfully transforms this into 01/03/3011. I have tried turning off auto-correct (can't be done) and auto-complete (makes no difference), and it is no surprise that these fail as neither really describes what Excel is doing, it's some sort of guess-my-shorthand-and-auto-transform-it non-feature and I'd really like to be rid of it forever as I paste long lists of module codes into Excel and may not notice that it has corrupted them with its own ideas about what I mean. I know I can prefix the code with a prime mark but why should I have to? </p>
