    What to Look for in Spreadsheet Software
    There are several elements of Spreadsheet programs, and some are more important to particular users than others. Regardless, here are the most important aspects to consider when evaluating which spreadsheet software is right for you:

    Compatibility
    Today, whether you choose to go with Microsoft Excel or not, you will still have clients and associates who are using Excel. That means that you will need to be able to open and save your work in formats that Microsoft can work with. This means that one of the most important capabilities your new spreadsheet program must have is the ability to be compatible with Microsoft Excel.
    Spreadsheet programs can be much more interactive and functional if they can be accessed by computer programs. When you’re picking the spreadsheet that will help you the most, you’ll want to make sure your pick will work with the programming language you’ll need to be using.
   

    Formula
    When you’re doing your calculations, you’ll want a lot of flexibility when you’re inputting which parts should be added, subtracted, multiplied, divided, averaged, etc. Although all of the programs have these functions, not all of them are so easy to work with. You’ll want a tool that enables you to repeat the formulas for each row or column that is newly-created.
    You’ll also want a spreadsheet that has a large number of built-in formulae you can choose from. After all, you don’t want to reinvent the wheel every time you try to prepare a complex spreadsheet.
    Formula, however, may not be the way to go. Why? Because every time you need a formula in a new spreadsheet, you pretty much have to rebuild it and that's why many people are using programming languages to build functions that can be reused over and over. Obviously this can save you a great deal of time if you tend to build complex formulae.
