Why use LEFT, RIGHT, MID functions? This wasn't explained further in the video.

Hi Tara, Good to hear from you. The reason why you would want to use these functions is that sometimes you will need only the left part of the data you are working with. For example if you have a column formatted in the following way: 2012.23.24.20421 2013.23.26.24032 2014.24.34.24202 Let's imagine that In this case, the four digits on the left could represent the post code of an address. You can use the LEFT function to retrieve the post code easily. There are many instances when you have to use these functions in Excel. This is just one basic example. Hope I was able to help!
