We all know that data validation is a very useful feature in Excel. You can use data validation to create a drop-down list in a cell and limit the values user can enter. But, do you know that you can use data validation in a multitude of ways to prevent users from entering wrong data?
Here is a practical application: Prevent users from entering duplicate values in a range of cells.
For eg. you are making an invoice. Wouldn’t it be cool if Excel prompted you when you enter a duplicate line item so that increase the item quantity instead of repeating it.
Here is a 3 step tutorial to do just that.
Step 1: Identify the range of cells where you want only unique values to be entered
This is simple. All you have to do is find the range where you want to control the user input. Lets say the range is B4:B11
Step 2: Set up Data Validation to prevent duplicate entries
Select the range (B4:B11) and go to data validation (Excel 2007: Data Ribbon > Data Validation, or press ALT+AVV)
Now, specify the validation type as “Custom”, this will allow us to use formulas to check for valid data. In our case, we need check if a particular entry is duplicated in the range B4:B11. This can be easily done using COUNTIF formula [learn COUNTIF Formula in plain English].
Go to the formula field and type the countif formula like this: =COUNTIF($B$4:$B$11,B4)<=1
Also, you can set up the “Error Alert” so that you can show a custom message when a duplicate value is typed, like “You have already added that product” message.
Once you set up error message, it will show up like this:
Step 3: Sit back and Relax
The third step is all too familiar. Now that you have prevented duplicate entries in your spreadsheets you can sit back and relax. May be read a few more spreadcheats.

8 Responses to “Top 5 keyboard shortcuts for Excel Charts”
As far as I remember (checked, again, 2 minutes ago) in my "Excel 2013" in order to select various chart elements I need to use the Arrow keys and not the TAB key.
Practically, the TAB key does nothing (within a Chart).

Thanks for pointing this out. This is how I remember it too, but when I was recording the video yesterday, only TAB key worked. MS must have changed the keys in Excel 2016. I have edited the post to include both keys.
The key navigation on charts is different in 2016.
TAB cycles through a layer of objects (SHIFT+TAB cycles backwards)
ENTER move down a layer
ESC moves up a layer
So on a column chart with title/legend/data labels if you select the plotarea the TAB will go through Title > Legend > Plotarea.
ENTER at plotarea will then select Vertical axis. Tab will take you through
Horizontal axis > gridlines > Series > Horizontal Axis.
ENTER with series selected will then allow you to TAB through individual data points and data labels.
If you ENTER on datalabels you can TAB through each data label.
ALT + F1 : to create default chart
ALT+E S T = CTRL + ALT + V, T : I find that easier to remember
I second what Michael already said about TAB and arrow keys. I can't help but think if this is related to the "," or ";" as separator. I prefer to use the chart tools - layout- drop down box, anyway.
Got to be F11 for instant charting. Highlight your data , hit F11 and voila! ?
Ctrl+1 is the most important chart shortcut. In fact, it works for any Excel object: whatever is selected, Ctrl+1 opens the task pane or dialog to format that object.
Somewhere along the line, maybe when Excel 2016 came out, the arrow keys stopped working to cycle through the elements of a chart. But what works is holding Ctrl while clicking the arrow keys. I haven't gotten used to the Tab and other keys, but as long as Ctrl+Arrow works, I'm good.
And F4 used to be so helpful when formatting a lot of charts. But since Excel 2007 came out, it has been mostly useless. It used to remember a whole set of changes at once, so I get that the newer modeless dialogs make that impractical. But now it only seems to work with formatting of lines and borders, and maybe fills. I find myself writing a lot of VBA one-liners in the Immediate Window to handle these tedious formatting tasks.
after clicking on a chart, is there a shortcut key to copy it?
Thank you for the Alt E S T - tip. This is more than a time saver. Because of dynamic charts or de-activated external references to data when you make the charts, you often have empty charts that are otherwise impossible to format. So this shortcut helps adressing that. I will work with it more and see if there remain some obstacles.
