It’s been almost a decade since I’m using this tool which is inevitable in many of our lives, people call it “Excel” and if used to its full potential, it can really save a lot of time and make us much more productive.
Wide range of activities from simple tasks like handling cash flow, expenditures, billing to complex things like data management and analysis on can be handling with ease and comfort.
If you are a programmer too, then you must take the benefit out of the tool that crosses through you at many phases of your life. Inbuilt mathematical formulas, visualization choice and its online editing capabilities are something to be appreciated.
It being a user friendly tool, a little mastery over it can ripe you awesome results with increased productivity added to it.
