Clean data quickly with Flash Fill

flash-fill-excelExcel 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.

    Great stuff! I can understand how to add a slicer to the pivot table, but how do you implement the departmental selector on the 'Filter' formula scheme?

  2. Claus Andersen says:

    Just saw this on your Youtube channel, and it’s areat idea...!

    An easy way to overcome the "ugliness" of pivot tables and get it to look nice (in the format of the Output sheet), would be to simply build a sheet with the nice map at the top, a pivot underneath it and a slicer next to formatted map and then reference each of the 9 cells in the formatted map to the “related” cell in the Pivot.

    Keep up the good work!

    Hi Chandoo,

    This is great! Curious how to make additional columns operate the same as the Department column (ex. have a "manager column") that would allow you to sort a 9 box by manager, area, or team in addition to department?

    Feel free to email me if needed! mfry01@minnetronixmedical.com

    Happy New Year

    • Ed says:

      I am curious about the smae thing. I would like to populate the 9 box with other views as well by adding additional columns. IE., I would like to add location, region, etc. Thank you.

  4. Matt says:

    This is great, thank you!

  5. Al says:

    How can i see the whole data set of all the teams in the output table. Need a formula that will pick up all the employees

  6. Heather says:

    Hello,
    Love the template. Thank you. Question - the drop down to pick a department on the Output tab does not seem to work on the downloadable template. Am I doing something incorrectly?
    Thank you!

    • Chandoo says:

      Hi Heather... Thank you. I am using Excel 365 to make the calculations. If you are using an older version of Excel, then the drop-down filter won't work.

  7. Rose says:

    Hi
    I was able to follow your 9 box grid and modified based my needs. However, you tutorial did not show how to you create the filter for the "Pick a department. Can you kindly share how to create that filter that updated the grid. Thank you.

  8. Rose says:

    I am working on this project but I am struggling with the data validation for the department. I copy the worksheets data entry and output as the managers want to see different tabs for each managers.
    I updated the source reference for each tab but It does not update the grid based on the new source. The list was updated but it does not populate the grid based on the performance and potential listed.
    In addition the hyperlink Update Data and View Talent Map no longer works. Can you please help me.

  9. Emmanuel Jose Vasquez says:

    I keep getting this error message in the pivot table:

    This formula is invalid or incomplete: 'The expression is not valid or appears to be incomplete. Please review and correct the expression.
    The following syntax error occurred during parsing: Invalid token, Line 1, Offset 14, ‘.

  10. Hi, I used your 9-box excel template with excel 365. First off, thank you so very much. It is incredibly helpful!! My only question is that the boxes aren't big enough for all of the employees (specifically the middle which we call 'Core Employee'). Is there a way to make the boxes larger? Even though it is in excel, I am not able to increase row height (like I normally do in a speadsheet). Any ideas? Thanks again, Jody

  11. Prish says:

    Hi Chandoo,

    Thanks for the great content. Re. 9 box grid, pls advise how do I increase the size of the box to accommodate more names?

  12. Nabil says:

    Merci Chandoo pour le modèle proposé,
    j'ai une question et un souhait est il possible de développer davantage ce modèle en insérant la photo de chaque employé.

  13. Leah says:

    Hi Chandoo!

    Great tutorial and tool, thank you! Your tutorial didn't include how to create additional filters on the "Output" tab. Could you please share how you did it?

  14. Geno says:

    Can this be done exactly in google sheets?

  15. Joanne says:

    Hi Chandoo,
    Thanks for the video it was really helpful. Is there any way to multi select the dropdown to display multiple or all departments rather than just one at once?

  16. Dana says:

    Hello Prish

    I have Microsoft 365 and I am struggling to make the boxes larger/unable to increase row height; any idea how you made this work? Specifically in the Output tab where the map is?

    Many thanks

  18. Connie Richards says:

    Is there a way to change the 9 box wording descriptions, i.e. Work Horses, to our own internal langauge?

  19. Zee says:

    Hi Chandoo, this is awesome and has worked perfectly. Due to a big organisation the 9 box grid on the output file is too small. I tried adjusting using the row/width ribbon under the format ribbon however it doesn't seem to work. Is there an easier way to adjust this?

    Thanks!

  20. Huy Nghi?a says:

    When I drag the formula, it doesn't work, and the order I use with the data changes. In the beginning, the order is it is " candidates," " potential," and " performance," but when it goes to another column, it is " Potential," Performance," and "Candidates."Can you help me? Thank you very much, sending love from vietnam

  21. Lucia says:

    Hi- I am working on the 9 grid project and I am trying to expand the box since I have over 100 names on a few of the columns. How do I do that?

  22. Zara says:

    Hi, Thank you this is great stuff and really useful.

    As well as department as demonstrated on your clip, how can I display all candidates on the grid at once?

    Many thanks in advance
