Validate Your Input Values You can use Excels Data Validation function to reduce the likelihood of bad data. This feature allows you to specify the conditions a value needs to meet and reject any values that dont meet your conditions. If you know, for example, the minimum and maximum values of your data, simply instruct Excel to highlight values that fall outside of that range. To take it a step further, create a drop-down list of values in an adjacent workbook, then use those to populate your active one. Youll limit your potential for error by choosing from an already known list of values. No fat finger errors here. Automate the Whole Thing Were biased, but the easiest and best way to prevent errors in Excel is to automate your work. Todays automation software packages (and there are many) work within and between your spreadsheets and other sources of data, like websites, to import, manipulate, copy, paste, and format data however you wish. Some log critical process information, sorts, and transforms data just like you would - through the presentation layer of the application. Unlike you (no offense), good automation software works without errors. If youre a CPA or work for any other firm that uses spreadsheets on a regular basis, consider automation software as an alternative to those every day manual processes.
The spreadsheet was introduced back in the 1980s and evolved into a complex program, but with the right experience it can be an effective tool for estimating large or small projects. Standalone programs work fine for estimating large projects; however they cannot estimate all structural elements of the project, such as, concrete, reinforcement, form-work, excavation, and back-fill at one time. Because of this restriction, contractors are forced to develop spreadsheet calculators ensuring bids were covering all required disciplines in their bids to ensure correctness. Construction bids missing important materials or a labor calculation is the number one reason companies incur large loses on projects they would generally have slim profits designed into the bid.
Avoid lots of Volatile Functions. A volatile function is one that re-calculates every time a work sheet changes. These include NOW(), TODAY(), OFFSET functions. If you use multiple or large amounts of these in a work book it will eventually start to slow it down. 5. Avoid Unnecessary Complex Formulas. One thing I have learned by developing spread sheets solutions for users is they (eventually) want to see all of the workings out of a formula. For example a typical sales formula of =(Price*SalesQuantity)-(Price*SalesQuantity)*Discount+(Price*SalesQuantity)*Tax Users will want to know the Sales Value Totals, the Discounted Totals and the Sales Tax Value displayed is separate columns. This is where we can break down the formula components into smaller formulas in their own columns or what we call helper columns. If you can increase transparency of calculations it will make the logic of the spreadsheet easier for users to follow resulting in less queries.
