Excel has many powerful & time-saving features. Even by Excel’s standard, Flash Fill is magical. Introduced in 2013, Flash Fill is a rule engine to Excel’s fill logic. Every time you type something in a cell, Excel will try to guess the pattern and offers to fill up the rest of cells for you. That is some serious time saving magic.
Let’s understand what Flash Fill is and few sample use cases.
Flash Fill, a smart rule engine
Flash fill listens to your every key stroke and tries to guess what you are doing. Remember Clippy from Office 97? Think of Flash Fill as Clippy’s less annoying & invisible cousin. Once Flash Fill identifies a pattern in your data entry, it offers a way to type rest of the data for you. If you accept the suggestion, the rest of the cells are automatically filled up.
Flash fill may not be a convenient option for simple patterns (like 1,3,5… or a bunch of dates or month names). But once you go beyond the realm of simple patterns, Flash Fill can be very useful.
Especially, when it comes to cleaning data.
Example 1 – Extracting numbers from text
Let’s say you are looking at some text data and want to extract the number portion.
Now, there is no simple way to do this. Any formula or VBA approach can be tedious.
But see what happens when you unleash Flash Fill on this unruly data.
Example 2 – Extracting first name from list of names
Again, writing a formula can be tricky ( LEFT(name, FIND(" ",name)) should work – more here).
But Flash Fill is faster and simpler. Just type the first few names and let Flash Fill do its magic.
Example 3 – Writing a bunch of formulas
Humor me with a scenario where you have customer names and you must lookup some corresponding data. Obviously you plan to use VLOOKUP for this. But the lookup table has other plans. Instead of customer name, the lookup table has firstname-initial_of_lastname. So for Bill Gates, the lookup table lists the name as Bill-G.
Of course, you can write a complex VLOOKUP. But why bother? Use Flash Fill to do the dirty work for you.
See below illustration to understand how this works.
Once the lookups are written, you can use FIND REPLACE (Ctrl+H) to add = at the front.
Flash Fill tips & tricks:
- Press CTRL+E to trigger flash fill. Excel will look at previously typed data and guesses the rest.
- To ignore Flash Fill suggestion, press ESC.
- By default, Flash Fill will be always listening and offers suggestions whenever it can. If you want to disable this, Use File > Options > Advanced and uncheck “Automatically Flash Fill” option. Click here for a screenshot of this process.
Do you Flash Fill?
Flash Fill is a fun and powerful way to clean data and get what you want. I use it often, when dealing with complex datasets.
What about you? Do you Flash Fill? When do you use it? Please share your tips and use cases in the comments.
If you have never Flash Filled, go ahead and try it today. See the magic yourself and share your story in the comments.

You are right, Chandoo. I was playing with the colour numbers last week and some of them don't appear different from each other. Others are totally different from yours.
@Duncan
Each version of Excel, post 2003, renders colors slightly differently
Different language versions may also have different default color palettes
Hello in french
excel 2010
colo1 = couleur1 = black
[couleur1]; [couleur2]; etc..
@Hui, thank you very much again for this great post.
However - under Excel 2007, Hungarian version your solution does not work with color names. I've tried both English and Hungarian names, but drops an error message "not valid formats"
Do you have any idea how to solve this issue?
thanks in advance
@Andras
Without a Hungarian version of Excel 2003 I don't think I can assist
Have you tried using the colour numbers? I couldn't get the names to work (despite using an english version of excel). but it did work with the numbers though. I left out the "u" and was easily able to produce burgundy using [color9]
Here a possible solution: find an English version of Excel, write there the formats using English names, then open the file in the Hungarian version and see the translation.
In Excel 2007 I can't get the colour names to work e.g Sea Green but the numbers do e.g color3 - colour3 does not work so I must bow to the country that has stolen my language (ha ha!)
Hey chandoo, nice Tip!
Wouldn't be easier just apply some conditional formatting for negative numbers and another for positive numbers? Or there's some cases that you can't do that?
Unfortunately the TEXT function doesn't color the cell as number formatting does.
Hi Hui,
Great post Sir, love the new way of formatting with color numbers.
I am using 2007, and it leads me to the last color number 56.
Thanks Hui.

Thanks Hui - works a treat!
Thank you, very helpful.
Trying to figure out if it is possible to apply color only to a part of the cell?
E.g. I have a value formatted as Accounting with a currency symbol.
Those I find somewhat distracting though necessary. If I could make them less obtrusive by coloring them gray while the number would stay black, that would be great. Tried tinkering with the format string, but didn't get the desired result. Single color for complete cell value works, but coloring just part of it could not be achieved. Maybe somebody managed that?
Exactly what I was looking for - thank you!
colour in the Australian doesn't work - we have to go American and no problem.
I always thought is was 56 colours notice you have 57. Cool.
thanks
