How to do group by in Excel - COINTIF function example

The Microsoft Excel is one of the best tools to analyze data and I think every programmer should be familiar with this tool. There are a couple of genuine reasons for why I am asking you to learn and master Excel. Since most of us work in Windows and Excel is almost always available, knowing how you can use it for your data analysis and reporting can really make a difference. Managers, Directors, Clients, and People at a higher level just love reports and once your experience grows, your responsibility also grows and you need to create many reports or work on Excel sheet generated by others. It automatically becomes part of your life, especially if you are progressing on project management space.
