#Excel Flash Fill in action with 16 examples

Excel Tip - Flash Fill

Flash Fill was introduced in Excel 2013.  After 6 years, it is still a hidden gem of modern Excel that most regular Excel users do not even know its existence.  Whenever I show to my colleagues what Flash Fill is capable of, they are all impressed and think that this is their “Greatest Discovery” moment.

So in this post, I am going to show you in a flash what Flash Fill can do with 16 examples.

Here’s the video on my YouTube channel.  Please turn on CC for English subtitles.


If you prefer reading to watching, you will see GIFs showing the examples below:

Are you convinced now Flash Fill is simply amazing?  However, in order to have Flash Fill worked well, you need to:

  1. Study your data and find the pattern
    • Flash Fill works well when there is a consistent pattern
  2. Input examples next to the data (table)
  3. Review the suggested results
  4. Teach” Excel with correction, when the suggestion is not correct
  5. ALWAYS check your results, esp. when there is more than one pattern

Last but not least, explore Flash Fill on your own!
