What are some good Microsoft Excel hacks to work fast?

Hi,Thank you for requesting an answer. I would suggest that you try to learn excel shortcuts specially ones that can help in using the Keyboard instead of a Mouse, you will realize that using Keyboard is really quick as compared to working with a Mouse.Number two is that you learn functions that are used frequently

What Microsoft Excel hacks changed the way you work?

Don't know that I'd call it a hack but Powerquery has completely changed Excel for me. I can automate repetitive tasks in under an hour usually and it's fairly easy to learn.I took a process of reviewing invoices that wasn't even being done manually because the files were too large and automated the entire thing in under four hours
