Reddit mentions of Microsoft Excel Data Analysis and Business Modeling (5th Edition)

You've got a lot of options, so I'm going to throw out a few I recommend, no particular order:

• Easy course on financial modeling that has a pretty good overview of basic excel functions. Great quick overview and an added bonus of learning some basic financial modeling concepts: https://www.udemy.com/financial-modeling-for-startups-small-businesses/learn/v4/t/lecture/6759908?start=0
  
• Book that I used in my summer before starting my post-undergrad consulting gig. Really good but a little deep/dense: https://www.amazon.com/Microsoft-Excel-Analysis-Business-Modeling/dp/1509304215/ref=sr_1_1?ie=UTF8&qid=1526764344&sr=8-1&keywords=excel+for+business+analysis
  
• Great website that starts from the basics, and you can skip forward to learn more:https://www.excel-easy.com/
  
• Surprisingly, some really great financial modeling videos put together by Martin Shkreli. As much of a dick that he is, he has some pretty good Excel skills and walks people through his methodology of building out models. He doesn't teach functions but you can look up what he does while you watch:https://www.youtube.com/watch?v=ARrNYyJEnFI
  
• My personal favorite for analysts that would reach out to me before starting asking for help. Great YT channel with lots of tips:https://www.youtube.com/channel/UCkndrGoNpUDV-uia6a9jwVg
  
  Disclaimer: I have not gone to B-School yet, but my experience with analysts that come from technical backgrounds is that Excel is a fairly easy tool to pickup. I wouldn't stress too much about learning before you get in.
  
  Hope it helps.

This is a good resource: https://www.amazon.com/Microsoft-Excel-Analysis-Business-Modeling/dp/1509304215/ref=sr_1_1?ie=UTF8&qid=1536926123&sr=8-1&keywords=excel+analysis

There is a great book by Wayne Winston which we pass around to all the new hires. It is excellent https://www.amazon.com/Microsoft-Excel-Analysis-Business-Modeling/dp/1509304215
