Blank cells are an invisible pain in the analysis. Dealing with them is frustrating, time-consuming and often very complex. At chandoo.org, we are not big fans of blank cells. That is why we wrote:
- How to delete blank cells & rows?
- Dealing with blanks – case study
- Quickly filling blank cells in a table
- Extracting non-blank data from a list
Today, lets talk about one more scenario. Lets say you want to find out the first non-blank item in a list. How would you do it?
Finding first non-blank item in a list
Lets say our list is in the range B3:B100.
Without using formulas
If you just want to get the first non-blank item in a list and do not want to use formulas, then you can remove all the blank items from the list. To do this:
- Select entire list
- Press F5, click on special
- Choose blanks, click ok.
- Press CTRL –
- Remove rows (or shift cells up as needed).
- Done!
Now that the blank cells are gone, just refer to B3 to get the first non-blank item in the list.
Using formulas
Although the non-formula approach works, it is manual. That means every time your data changes, you must repeat the steps. Not very cool, especially if you call yourself awesome. So, lets use a powerful formula to get that first non blank item in our list.
First see the formula:
=VLOOKUP("*", B3:B100, 1,FALSE)
How it works?
We want to lookup for first cell that contains something. It does not matter what that value is.
That is what * does. * is a wild card in Excel. When you ask VLOOKUP to find *, it finds the first cell that contains anything.
NOTE: This approach finds first cell that contains any TEXT. So if the first non-blank cell is a number (or date, % or Boolean value), the formula shows next cell that contains text.
How to find first non-blank value (text or number)?
If you want to find first non-blank value, whether it is text or number, then you can use below array formula.
=INDEX(B3:B100, MATCH(FALSE, ISBLANK(B3:B100), 0))
Make sure you press CTRL+Shift+Enter after typing this formula.
How this formula works?
ISBLANK(B3:B100) portion: This gives us list of TRUE / FALSE values depending on the 98 cells in B3:B100 are blank or not. It looks like this:
{TRUE;TRUE;TRUE;FALSE;FALSE;FALSE;FALSE; ...}
MATCH(FALSE, ISBLANK(…), 0) portion: Once we have the TRUE / FALSE values, we just need to find the first FALSE value (ie, first non-blank cell). That is what this MATCH function does. It finds an exact match of FALSE value in the list. (Related: Using MATCH Formula)
INDEX(B3:B100, MATCH(…)) portion: Once we know which cell is the first non-blank cell, we need its value. That is what INDEX does. (Related: Introduction to INDEX formula)
Home work for you
If you like this formula and want some challenge, read on.
For these home work problems, use the range B3:B100 or named range list in your formulas.

Drawing a blank when working on lookups?
If you are giving blank stares whenever your boss asks for lookup related stuff, then you are going to love this. My latest publication, The VLOOKUP Bookis a comprehensive guide to VLOOKUP, INDEX, MATCH, LOOKUP and other techniques to lookup any data and answer questions with confidence.

Comprehensive and easy to understand
This is a book for everyone who uses Vlookup. Most of us think… Oh.. I already know the function. But this book will open your eyes to some brilliant techniques. – By Dr. Nitin Paranjape
Solid introduction to lookup functions
This books does a wonderful job of taking each of the lookup functions available in Excel, breaking them down to a simple, easy-to-understand level. – by Lucas Moraga |

I think the virtue of pie charts is precisely that they are difficult to decode. In many contexts, you have to release information but you don't want the relationship between values to jump at your reader. That's when pie charts are most useful.

Chandoo,
millions of ants cannot be mistaken.....There should be a reason why everybody continues using Pie charts, despite what gurus like you or Jon and others say.
one reason could be because we are just used to, so that's what we need to change, the "comfort zone"...
i absolutely agree, since I've been "converted", I just find out that bar charts are clearer, and nicer to the view...

Martin

Chandoo -
You ask "Can I use an alternative to pie chart?"
I answer in You Say “Pie”, I Say “Bar”.
This visualization was created because it was easy to print before computers. In this day and age, it should not exist.
I think the 100% Bar Chart is just as useless/unreadable as Pies - we should rename them something like Mama's Strudel Charts - how big a slice would you like, Dear?
My money's with Jon on this topic.
The primary function of any pie chart with more than 2 or 3 data points is to obfuscate. But maybe that is the main purpose, as @Jerome suggests...
@Jerome.. Good point. Also sometimes, there is just no relationship at all.
@Martin... Organized religion is finding it tough to get converts even after 2000+ years of struggle. Jon, Stephen, countless others (and me) are a small army, it would take atleast 5000 more years before pie charts vanish... patience and good to have you here 🙂
@Jon .. very well done sir, very well done.
good points every one...
I've got to throw my vote into Jon's camp (which is also Stephen Few's camp) -- bars just tend to work better. One observation about when we say "what people are used to." There are two distinct groups here (depending on the situation, a person can fall in either one): the person who *creates* the chart and the person who *consumes* the chart. Granted, the consumers are "used to" pie charts. But, it's not like a bar chart is something they would struggle to understand or that would require explanation (like sparklines and bullet graphs). Chart consumers are "used to" consuming whatever is put in front of them. Chart creators, on the other hand, may be "used to" creating pie charts, but that isn't an excuse for them to continue to do so -- many people are used to driving without a seatbelt, leaving lights on in their house needlessly, and forwarding not-all-that-funny anecdotes via email. That doesn't mean the practice shouldn't be discouraged!

Good article. Is it possible to do that with line charts?
Hi,
Is this available in excel 2013?
