Reshaping your data easily – Case study [Pivot tables FTW]

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.

data-and-expected-output-reshaping-with-pivots

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.

    Quite a nice and helpful article. I am sure excel is one of the most used application across many many big companies. And your info on project status update using excel would surely be usefull. Keep up the good work on this blog site. Also to share there are some open source flash-based graphing and charting solution which caould also be used on any project..

  7. Chandoo says:

    @Alex, Izabel .. thank you 🙂

    @Miguel: Thank you. Your dashboard looks very good. It is inclined towards the budget and finances of the project. I have kept those aspects out of this series. May be I will revisit the financial aspect of projects at a later point.

    @Rishil: Thank you. Yes, you can create flash based charts (or even simple image based charts) and embed them in a project dashboard that can be published to the team using intranet (like sharepoint). This is how large companies usually do it. Thanks for sharing the Askwiki article.

  8. Tim says:

    Great looking dashboard!! Do you have a version for the Mac versions of Office available?

    Thanks

    Chandoo,
    this is great piece of collating info.I liked it and shall try using it in office.
    Thanks for the all hard work behind this.

    Chandoo,

    Kudos. This is really as simple as it gets for laymen. We did this sort of stuff in Consulting - but this can now become really simple for people. Will have my team look at this! Great work.

    thanks,

    Just downloaded the project management template bundle...great!

    Have you done anywork on a Project Portfolio Dashboard template?

  13. Chandoo says:

    @Bw... Thanks for getting a copy of the templates. 🙂 I have worked on few assignments where we built such templates. But these are similar to other regular dashboard templates. I will share some of these ideas in a later post someday. Meanwhile if you have any ideas on how to structure project portfolio dashboard, let me know using comments or email.

    Thanks fro the great ideas! To get a sense of the layout and design of a Dashboard more geared toward Cost and Schedule anaysis, check out the example Dashboard at http://www.ProjectDashboards.com which was built entirely in excel.

  18. DS says:

    hey,

    i just need a simple Chart where by i can show some of the projects by % wise. no dates required.

    1st column Project name and 2nd column will be status (filled with %). can you pls help me out.

    Thanks.

  19. Chandoo says:

    @DS... if you have excel 2007, you can use data bars in conditional formatting for this purpose.

  20. Larph says:

    Hi Chandoo - this series is an excellent resource and tutorial, thank you for sharing.

    When I sat down to consider what my dashboard should look like, one of the most important features for me is to be able to maintain version control and to show simply on what version is on display.

    Apart from the naming convention of the file name, is there a good way to do this within a dashboard? I'd be interested to hear your thoughts!

  21. Chandoo says:

    @Larph: Welcome 🙂

    > You can do version control thru Macros (but always remember that your audience can disable macros)

    > Another option is to use a static time stamp / version number in the title page of dashboard that you update manually whenever you make changes to the file

    > In excel 2010, you can keep track of file versions from File menu. This can be used to select a previous version of dashboard.

    > Best option is to use a version control system like SVN or upload files to Sharepoint or something like that. This will take care of versioning for you (although it is a bit technical and dashboard audience may have difficulty figuring the versions out).

    > The easiest option is to use filenames and the CELL() formula to get the version number (or date) from the filename so you can show it on the dashboard.

    On the dashboard when I print, the text is blanked out in the middle of the Issues list - suggestions on how to fix?

  24. Neil Joseph says:

    Hi Chandoo, do you have an equivalent Project Management Dashboard / Project Status Report for MS Office 2010?

  25. Paul Brown says:

    As a Microsoft trainer I'm interested in your choice of Excel for project management. I'm assuming that you've tried Microsoft Project and have decided not to use it? We get folks on our MS Project courses who've tried to use Excel for PM purposes and none of them have made such an impressive project plan, but I wonder is it worth all the effort?

  26. Arc Nteimam Finomo says:

    This looks very interesting. How may I be a part of this

    Does this template work in Google Spreadsheets?

    Hi Chandoo,
    Your PM dashboards impressed me so much that I've downloaded the Portfolio and Project Management package.  All of the documents look very professional.
    I was going through the Portfolio dashboard and I had a question.  
    When I enter in additional holidays they are highlighted in the gantt chart.  Is it possible so that the name of the holiday shows up in the highlighted area of the gantt chart.
    Thanks
    Adam

    can you confirm that the downloads will work on a mac - excel for mac v14.3.6

    thanks

  32. Paul says:

    Made a slight variation on the schedule sheet,

    1. Add a date column for start
    2. In week column cell use =weeknum() and link to date cell
    3. Hide week column

    When you enter in a date for each task the week number is populated accordingly
    simple but more effective, you can also dynamically link the date cell to your MSP project file for even more automation!!
