Late. Jayaram, my uncle is also a teacher. When I was a kid, I used to spend a lot of time with him, learning all sorts of things. He taught me chess, maths and so many life lessons. I remember one such lesson very vividly.  One day, he asked me to do something. I did it in a very long way. After seeing me struggle for several minutes, he chipped in and showed me how to do it easily. He then said, “when someone asks you where your nose is, you don’t twist arm around your head. You just point to your nose directly.”

The idea is that when you have a direct, simple way to do something, you should use it.

Nose and pivot tables… how are they connected?

We are coming to the point. Recently, learneagerly, one of our forum users asked a question about how to transform (reshape) a set of data in Excel.

Marc L, one of our Excel ninjas, posted an awesome VBA script to do that.

Later in the day, I chipped in and shared a formula approach to transform the data.

I suggest checking out both approaches for learning more about VBA & INDEX formula respectively.

After posting my answer, I got thinking… May be there is a more direct way to reshape the data.

Why, yes, there is. You can use Pivot Tables.

Let’s take a look at the data & problem first

Here is a snapshot of raw data and expected output.

As you can see, we have two columns of data and we need to extract n (here it is 6) items from first column, then from second column and lay them out in output. We repeat this until we run out of the data.

Reshape this thing with a Pivot

raw-data-reshape-with-pivots-v1The first step is to add two extra columns to your raw data. Let’s call them Running & Repeat.

  • Running: with numbers 1 thru 6 and repeat the pattern (just auto fill or copy paste)
  • Repeat: with 6 cells of 1, 6 cells of 2… and repeat this pattern (auto-fill)

But what if I want a different n

Even better. use formulas. Let’s say your data starts from H6:I6

  • Running:  =MOD(ROWS($I$6:I6)-1,n)+1
  • Repeat:  =IF(J6=1,SUM(K5,1),K5)

Related: Using ROWS() to generate running numbers in Excel.

Now that we have these extra columns, select all the data (2 columns of data + 2 extra columns we just added) and insert a pivot table.

Set up the report by,

  • Adding Repeat & Running to row labels area (in that order)
  • Add Col A & Col B to values area.
  • Move the ? values to row labels area (by dragging it)
  • Position ? values between Repeat & Running row labels.
  • Your pivot report’s last column will have the transformed data.
  • Viola, nose pointed!

How do you reshape your data?

Pivot Tables and Power Query are my go to tools for almost all kinds of reshaping problems. Often, I indulge in INDEX formulas or a bit of VBA. For example, just a few days ago, I had to split first 100,000 digits of Pi ? in chunks of 3 digits, 3 digits and 14 digits in a pattern. As the data is too long, loading it Excel cell was impractical. Loading it in to multiple lines with each having digits was impractical (as I may need to split them in another pattern). So I used a simple VBA script to zap the data and get what I need.

In case you are curious: I made a chart to celebrate the Pi day (14th of March) with our community on Twitter.

But when I am not splitting irrational stuff, I usually rely on Pivot tables or PQ.

What about you? How do you reshape your data? Please share your approaches and tips in the comments section.

    We have only just got excel 2007 so this is helping me navigate my way through the differences cheers.

    For Macro's i always add a Command Button, rename it something obvious, change the colour of it and finally add the following to its View Code section.

    Application.Run "MAcro1"

    This way anyone opening the file knows what to do if i ever win the lottery and dont make it in 🙂

  2. Ron Murphy says:

    Hi,
    Good article. But I have this problem.
    1) Customized QAT with a macro. Macro name = MacroX
    2) Runs OK from original location (e.g. C:\TestLoaction1\TestFile.xls)
    3) Copy past file to new location (e.g. C:\TestLoaction2\TestFile.xls)
    Menu button now fails:
    Cannot run the macro "C:\TestLoaction1\TestFile.xls'!MacroX' The macro may not be available in this workbook...

    Of course the code is there, and macros are enabled.

    Could get it to work after deleting and recreating macro custom buttons. So have to re-assign macro to QAT button every time I move the file?

    If I put a form button on he worksheet and assign the macro to that, it's location independent.

    Any ideas?
    Thanks

    @Ron
    What you have said is correct
    Macros within a worksheet are stored within the worksheet and hence follow it.
    Macros referenced by a button in the QAT or elsewhere are locaed in a file and if that file is moved the linkages don't follow.

    The easiest way around this is to store all your macros in a location that doesn't move and is in fact reloaded everytime that Excel starts and that is called the Personal.xlsx/b file.

    These are refered to several time at Chandoo.org or have a read of
    http://www.rondebruin.nl/personal.htm
    or

    • Col Delane says:

      In Excel 2003 and prior versions, a button added to the Toolbar maintained a DYNAMIC link to the file (e.g. Personal.xlsb) holding the assigned macro, such that if the file was relocated for any reason (by using Excel's native Save As command rather than just moving it via Windows Explorer), the link between the button and the file was updated.
      I expected the same to occur with Excel 2007+, but alas, Microsoft in their infinite wisdom have removed another feature useful to advanced users (just as they did by removing the ability to design your own buttons)!!
      So having just done some reorganisation of my files, I now have to remove and recreate every friggin macro button on my QAT (I have lots) - what a pain in the proverbial!!

  4. Ron Murphy says:

    Hi Hui,

    Thanks for the help, that's really useful.

    1) The macros I'm adding are for one specific Excel application, so I really wanted the macros to follow the file

    2) I didn't want to have to pass other files around too and have users installing those - either Personal.xlsx/b or as an Add-In.

    3) I realise now that the QAT additions will appear for other Excel workbooks in which I don't want the macros available.

    So, it looks like I need to keep it local, by using a button on the worksheet. Unless you can suggest any way of adding to menus just for a specific workbook.

    Thanks again for your help. Great site, so I'll be signing up for the emails.

    Ron

  5. cheryl says:

    I know I'm a little late jumping on this post, but wondering if anyone knows how to add a UDF to the QAT? I've saved my UDF in my personal workbook, but it does not show up in my list when I choose Macros when customizing my QAT. Suggestions? Thanks!!

    • Chandoo says:

      @Cheryl: UDFs cannot be accessed like Macros. You can use them from other macros or from worksheet cells as formulas...
      @David: If you save your macros file and then install it as an add-in then it will be always available for you.

  6. David says:

    The instructions work great when you are creating a new file, and it is still open. I find that I can't access macros after I've saved a file as an xlam and closed it. When I reopen the xlam, either by browsing to it, or by having it set to open as an addin using Excel Options, the macros are no longer available in the macros list when I go to edit the QAT. Any way around that?

  7. JimH says:

    I need to create a button that will run a macro. Once you click the button it needs to open up a browser asking you to select a report/file. Once you select the file, it will run the macro on the selected file and then save it as a new report with a name and the current date. I created the macro to sort/modify the report but I do not know how to do what I mentioned above. I hope this makes sense.

  8. NathanG says:

    I'm having trouble adding a macro to the QAT. I've done everything up to step 5 but my macro isn't showing up. What am I doing wrong?

  9. surfinette says:

    Hi,
    Thank you for the explanation. Very useful for a recent switcher from office 2003 to office 2010.
    My follow-up question is: in Excel (or ppt) 2010, can you customize the macro button that you put in the QAT?
    In office 2003, once you chose the custom button for your Macro, you could then edit pixel by pixel the said button.
    For instance, I've created 2 Macros in PPT that are converting all my slides to either English or French language, so I'd like one button to show EN and the other FR... that would be more meaningful that any of the possible "custom" office 2010 buttons

  10. Morton Wakeland says:

    I read all the post and one important aspect to the QAT was never mentioned. That is, you have a macro driven worksheet that you want to share with other. You have customized the QAT with two icons to run the macros (VBA programs in reality). However, when the others receive the workbook, the icons are no where to be found. It's my understanding those "customized buttons" have been saved to an outside file, Excel.qat. QUESTION: Could one simply attach that file to your email, along with the worksheet, and tell the recipients to copy that file to correct location on their computer - C:\Users\\AppData\Local\Microsoft\Office|\
    Would the customize macro buttons then appear in the worksheet and, more importantly, work? Thanks for your thoughtfulness and thanks for well written instructions Chandoo!
