If you are doing a task again a again in excel you can automate it with a Marco. If you receive a data every day/Week/Month that you analyse the same way every time, you can create series of commands in shape of excel macro and do that task by single command of running that macro and completing your task by single click of mouse.
A macro records your mouse clicks and keystrokes while you work and lets you play them back later. You can use a macro to record the sequence of commands you use to perform a certain task. When you run the macro, it plays those exact commands back in the same order, causing Excel to behave just as if you had entered the commands yourself.
Macros are easy to create: you tell Excel to start recording, perform actions as you normally do, and then tell Excel when you're done. Behind the scenes, Excel uses a programming language called Visual Basic® for Applications (VBA) to record your instructions. You don't have to know anything about programming or VBA to create and use macros that will save you time and make your work easier
