Find first non-blank item in a list with formulas
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:

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).
Now that the blank cells are gone, just refer to B3 to get the first non-blank item in the list.
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:
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)
