With Excel, your formulas, charts, and reports are only as good as the data you enter. So, if you’re responsible for entering a vast data set, it’s important to minimize the risk for error.
If you don’t, the repercussions could prove disastrous (for evidence, see our earlier article).
We have already covered one key strategy for avoiding data input errors: use an Excel form. Excel also comes with other options to help streamline the chore of data entry while also helping to ensure accuracy.
It’s easy enough to type a value into the wrong column, or to miss or misplace a decimal point. If you know how to use Excel’s Data Validation tool, you can at least ensure that each value you enter matches the general parameters for its cell.
To enable Data Validation for a selected range, click the Data tab and the select “Data Validation” from the drop-down Data Tools menu. This opens the Data Validation dialogue.
With “Allow” drop-down, you can set the general data type (date, time, number, text, etc.). You can then use the remaining fields to define other characteristics. In this example, we’ve specified that each value entered must be a time between 8:00 a.m. and 6:00 p.m.
You can use the other tabs in the Data Validation dialogue to define an input message (displayed when you select that cell) or an error alert (displayed if the data you enter fails to match your parameters).
If you have a finite list of possible values for a field, you can use the Data Validation dialogue to create a drop-down menu in Excel. Choose “List” as your option under the “Allow” drop-down. You can then enter a set of possible values, separated by commas, under “Source.”
In the example below, we have created a list containing the four points of a compass. Once you’ve set up your list, you will see a drop-down menu every time you click to enter data in that range.
A drop-down menu can speed things up, and will eliminate typos (like “Nort” and “Weast”).
Excel can also supply a drop-down menu while you’re entering text data (this trick will not work for numerical cells). If you press [Alt]+down-arrow (you can also right-click and choose “Pick From Drop-down List”), you’ll see a list containing all the corresponding values from the previous rows.
In the example shown below, Excel allows us to choose from a list of company departments, based on the values entered earlier.
As you manually enter data, Excel will offer autocorrect suggestions based on your earlier entries. In the example below, when we type “AD,” Excel offers to fill in the “MIN.” Just hit [Enter] and save yourself a couple of keystrokes (these can add up over the course of your day).
As handy as AutoComplete can be, it can also prove distracting—especially if you’re entering values that resemble each other but don’t precisely match up. It can be tempting to hit [Enter] when the opportunity presents itself.
If the app is consistently offering you wrong guesses, you should know how to disable Autocorrect in Excel. Click the File tab, choose Options, and click Advanced in the left sidebar. Uncheck the box beside “Enable AutoComplete for cell values.”
A wide, monochrome spreadsheet can turn your data-entry brain to mush. To help keep yourself oriented, consider giving each column its own distinct fill color. To color-code columns in Excel, select each column and either right-click and choose “Format cells…” or click on the fill-color button in your toolbar (it looks like a spilling can of paint).
It’s a bit of a recurring theme in our articles: Sheetcast can help you address most of your issues in data collection and data entry. With Sheetcast, you can easily create a web app in Excel, complete with the elegant data validation tools offered within Excel. Your users can enter their own data themselves—simultaneously and in real time—using any browser or mobile device. Administrators can set up automatic notifications to help them keep tabs on their growing data set, and to flag them immediately if problems arise.
If you can use Excel, you can build your own web apps, in minutes. Visit the Sheetcast website for demos and information.
N-nyiimock Bitanyanmi is a welcome and familiar face in the online Excel community, where he often goes by the name Justice. Behind his enthusiasm, knowledge, and eagerness to learn, however, lies a surprising fact: until he was almost an adult, he had rarely laid hands on a computer.
Pretty much anyone who has ever used Excel has a horror story or two to share—a misplaced decimal, a missing minus sign, a botched cut-and-paste, or some other minor blunder with potentially major consequences.
Too many of us are cautious in our daily lives, but cavalier with the safety and security of our spreadsheets.
Excel forms have improved my life. Now, I know there’s something even better (stick around to the end of this tutorial).
For years, Excel users have been able to collaborate on shared workbooks. By making it possible for multiple users to work together on a single file, Microsoft unlocked countless ways to boost efficiency and productivity.
Microsoft Excel debuted on the Macintosh in 1985 and came to Windows in 1987. Three and a half decades later, its name remains virtually synonymous with the very concept of “spreadsheets.”
The Necessary Evolution from Excel Spreadsheets to Web Apps. Like many of the greatest technologies of our time, spreadsheets can be our salvation or our downfall – and with great power comes great responsibility.
Sheetcast enables you to convert Excel spreadsheets to web apps directly in Microsoft Office, a tool you already use every day. Sheetcast is affordable, easy to learn, and has hundreds of potential uses (limited only by your imagination).
Maybe you’re a bit of an Excel guru. Your workmates frequently marvel at your ability to get the most out of the app, employing functionality they never even knew existed.
