Last week we saw a really cool holiday request form made by Theodor.
This week, we will learn how to combine conditional formatting and data validation to create an awesome data entry form.
First see a demo to understand what I mean:

How to create such a data entry form?
Very simple, just grab a cup of coffee (or your favorite fried-nuts-crushed-and-brewed-with-hot-water) and follow my lead.
Step 1: Set up Data Validation
Assuming you need to gather some inputs, like shown above. First thing to do would be setting up data validation rules in a cell so that your users can specify the type of data they are entering. For eg. they can choose card or paypal or other as payment mode and depending on that, enter further details.
To do this, just select the cell and go to Data > Validation. Choose “List” as the rule and give values.

Step 2: Add conditional formatting rules.
Now, based on the selected value, we need to highlight a set of cells.
Assuming all the data to be gathered in cells C4:G4,
Select first two cells (C4:D4), go to Home > Conditional Formatting > New Rule
Here, we need to tell Excel to highlight the C4 and D4 if the type of payment is Card.
So choose the CF rule type as “Use a formula to determine which cells to format” and the check if $B4 is “card”.

Step 3: Add Conditional Formatting rules to other cells (E4:F4, G4)
Using the same logic.
Step 4: Bask in glory!
That is all. There is no step 4. We are done. Finish the coffee or whatever you mixed with hot water. Just save the file and send it to your customer, vendor or boss. Bask in glory as there will be fewer data entry mistakes and more awesome.
Home work: Get Creative and do more
You can use some creativity and make the data entry form even more awesome. For example, you could show a tick mark when the data entry is complete. Also you could highlight only when the cell is blank (ie if the data is already entered, there is no point highlighting)
See what I came up with:

I am not going to tell you how to do the above. That is for you to figure out.

And if you can not solve the homework problem, download this file and examine it.
How do you make your data entry forms awesome?
I love data validation. It makes the whole process of gathering valid data dead simple. Also, it is an excellent way to change month or other settings in dashboards. (example 1, 2, 3)
What about you? How do you use Data Validation and other excel features to make your input forms both simple and awesome? Please share your experiences and ideas using comments. Go!

Some great contributions here.
Gotta love the Friday 13th formula 😀
Great tips from you all! Thanks a lot for sharing! bsamson, particularly you helped me on a terribly annoying task. 🙂
(BTW, Chandoo, it's not exactly "Find if a range is normally distributed" what my suggestion does. It checks if two proportions are statistically different. I probably gave you a bad explanation on twitter, but it'd be probably better if you fix it here... 🙂 )
Great compilation Chandoo
For the "Clean your text before you lookup"
=VLOOKUP(CLEAN(TRIM(E20)),F5:G18,2,0)
I would like to share a method to convert a number-stored-as-text before you lookup:
=VLOOKUP(E20+0,F5:G18,2,0)
@Peder, yeah, I loved that formula
@Aires: Sorry, I misunderstood your formula. Corrected the heading now.
@John.. that is a cool tip.
Hey Chandoo,
That p-value formula is really great for a statistics person like me.
What a p-value essentially is, is the probability that the results obtained from a statistical test aren't valid. So for example, if my p value is .05, there's a 5% probability that my results are wrong.
You can play with this if you install the Data Analysis Toolpak (which will perform some statistical tests for you AND provide the P Value.)
Let's say for example I've got two weeks of data (separated into columns) with the number of hours worked per day. I want to find out if the total number of hours I worked in week two were really all the different than week one.
Week1 Week2
10 11
12 9
9 10
7 8
5 8
Go to Data > Data Analysis > T-Test Assuming Unequal Variances > OK
In the Variable 1 Box, select the range of data for week 1.
In the Variable 2 Box, select the range of data for week 2.
Check "Labels"
In the Alpha box, select a value (in percentage terms) for how tolerant you are of error.
.05 is the general standard; that is to say I am willing to accept a 95% level of confidence that my result is accuarate.
Select a range output.
Excel calculates a number of results: Average (mean) for each week's data, etc.
You'll notice however that there are two P Values; one-tail and two-tail. (one tail tests are for > or .05), the number of hours I worked in week two is statistically equivalent to the number of hours I worked in week one.
So here’s a way you might want to use this. You put up a new entry on your blog. You think it’s the best entry ever! So you pull your webstats for this week and compare it to last week. You gather data for each week on the length of time a visitor spends on your website. The question you’re trying to prove statistically is whether there’s an average increase in the amount of time spent on your website this week as compared to last week (as a result of your fancy new blog post). You can run the same statistical test I illustrated above to find out. Incidentally, it matters very little to the stat test whether the quantity of visitors differs or not.
Anyhow, the Data Analysis toolpack doesn't perform a lot of stat tests that folks like me would like to have access to. In those cases I have to either use different software, or write some very complicated mathematical formulas. Having this p-value formula makes my life a LOT easier!
Thanks!

Fantastic stuf..One line explanation is cool.
Thanks to all the contributors
OS
Take FirstName, MI, LastName in access (you can fix it to work in excel) capitalize first letter of each and lowercase the rest and add ". " if MI exists then same for last name:
Full Name: Format(Left([FirstName],1),">") & Format(Right([FirstName]),Len([FirstName])-1),"") & ". ","") & Format(Left([LastName],1),">") & Format(Right([LastName],Len([LastName])-1),"<")
I teach excel, access, etc etc for a living and i have my access students build this formula one step at a time from the inside out to show how formulas can be made even if it looks complicated. Yes I know I could just do IsNull([MI]) and reverse the order in the Iif() function but the point here is to nest as many functions as possible one by one (also I illustrate how it will fail without the Not() as it is)
Extract the month from a date
The easiest formula for this is =MONTH(a1)
It will return a 1 for January, 2 for February etc.
if in a column we write the value of total person for eg. 10 if we spent 1.33 paise each person then how we get total amount in next column and the result will in round form plzzzzz solve my problem sir................... thank u
@Anjali
If the value 10 is in B2 and 1.33 paise is in C2 the formula in D2 could be =B2*C2
If the values are a column of values you can copy the formula down by copy/paste or drag the small black handle at the bottom right corner of cell D2
kindly share with me new forumulas.
