A Comprehensive Guide on Excel Flash Fill

Excel Flash Fill comes in handy when using string manipulation functions like the trim() method to the entire column. Now, the process would not seem tedious for a couple of rows but can be a little hectic when you have thousands of rows. Excel Flash Fill can be employed to finish the time-consuming task within a couple of keystrokes. 

What Is Excel Flash Fill?

Excel Flash Fill is a feature of Microsoft Excel where Excel can sense a pattern in the cell and apply the logic to extract a similar resultant pattern out of the remaining cells in the table. 

The definition could be a little confusing, so go through an example.

Example for Excel Flash Fill

Now, assume that you have an automobile product data table. The table has one column that stores the geographical region code, manufacturer code, and automobile type code.

Example:

Let us assume that you have an automobile code as “NOR-HON-SUV”

Here, NOR is North for Geographical Code, HON is Honda for Manufacturer Code, and SUV is an automobile type code.

Imagine you need to identify these patterns individually and generate three different columns based on geographical region code, manufacturer code, and automobile type code from the original column.

This could be done using a bunch of functions like TRIM() etc. But, the process could seem a little complicated and time-consuming. What if you could do it with a few keystrokes?

That is precisely where Excel Flash Fill comes to play. You can press a set of keystrokes, and the data will be automatically split and segregated. 

Sounds interesting, right? Now, enter the next section and try to understand how exactly Excel Flash Fill works in real-time. 

How to Implement Excel Flash Fill?

In the following example, you will include product-related data. In column A, you have the product code, product serial number, assembly code written altogether. Now, the goal is to separate them into three different columns. As shown in the first row of the image.

Now to do so, all you have to do is go to the next successive cell and press and hold the control key in Windows or Command key in Mac, then press the alphabet 'E.'

CTRL + E or CMD + E

Now, sometimes, very rarely, Microsoft Excel might fail to recognize the patterns; in such scenarios, you can help it by filling two or more rows to help Excel get familiarised with the pattern requirements. Then, you can press CTRL+E or CMD + E to fill all the successive cells.

A sample is shown in the image below.

The final resultant data table would look like this in the image shown below.

This feature can be applied to any type of data, regardless of string length or data type.

For example, print the content in the 4th to 8th location of strings with different string lengths.

Let us consider the example below. In this example, you have strings of different lengths, and also, you have included a cell with numerical data.

Excel-Flash-Fill-Demo-4

This example has filled the first two resultant cells so that excel could compile the expected pattern. Now, in the third cell, it has used the Excel Flash Fill shortcut, CTRL + E or CMD + E, and the remaining cells have gotten filled with data between the 4th to 8th location of strings as shown below.
