Greetings from Atlanta, GA. I have been a student of Chandoo for several years and have benefited greatly from learning techniques and tricks from this website. While my Excel skills may seem advanced to some, there are a few things I just have no clue how to start and the reality is that I know nothing compared to the people I meet on this forum. I would like Excel to take a gigantic data file and bust the data up based on words contained in the data? For example, one of the columns of data has the name of a customer and then there are 5000 rows of data with that customer name in it. I would like to have Excel bust the data up onto separate worksheets for each customer. Is that even possible? If it is what class do I need to take to be able to learn how to do it? For example, my data file has 110,000 lines of data that pertain to about 50 different customers.
