I know that Excel is a very powerful and useful tool that can be used at the workplace, at school, in any kind of business. I never had a necessity to use it at work. I know that excel is used for more than what I use it for. Complicated calculations and analytical operations are the advantages that I know about, as well as simple view of the spreadsheet.
Unfortunately, I can’t tell that I am proficient with excel, yet eager to learn. Right now I am using it for scheduling my days. It makes it easier that I don’t need to draw a table, and corrections are easy. Another thing I do on excel is I organize the data, such as phone numbers and other information about other people(contact info).
It is surprised that you even use Excel to store phone numbers at home. This is great that you still have back up even you lost your contact numbers in your phone.
I am also very impressed that you try to use Excel for your personal use. Great way to practice!
