Have you ever been in a VLOOKUP hell?

Its what happens when you have to write a lot of vlookup formulas before you can start analyzing your data. Every day, millions of analysts and managers enter VLOOKUP hell and suffer. They connect table 1 with table 2 so that all the data needed for making that pivot report is on one place. If you are one of those, then you are going to love Excel’s data model & relationships feature.

In simple words, this feature helps you connect one set of data with another set of data so that you can create combined pivot reports.

Practical Example – V(X)LOOKUP hell vs. Data Model heaven

Lets say you are looking sales data for your company. You have transaction data like below.

Example data

And you want to find out how many units you are selling by product category and customer’s gender.

Unfortunately, you only have product ID & customer ID.

With VLOOKUP Hell,

  1. You first fetch all the customer and product data and place them in separate ranges.
  2. Then write a vlookup formula to fetch product category, another to fetch customer gender.
  3. Then fill down the formulas for entire list of transactions.
  4. Now make a pivot table.

Assuming you have 30,000 transactions, you have to write 60,000 VLOOKUP formulas to create this one report!!!

With Data Model heaven,

  1. Create relationships between Sales, Products & Customer tables
  2. Create a pivot table

Creating a relationship in Excel – Step by Step tutorial

  1. Relationship feature in Excel 2013 data ribbon tab
    First set up your data as tables. To create a table, select any cell in range and press CTRL+T. Specify a name for your table from design tab. Read introduction to Excel tables to understand more.
  2. Now, go to data ribbon & click on relationships button.
  3. Click New to create a new relationship.
  4. Select Source table & column name. Map it to target table & column name. It does not matter which order you use here. Excel is smart enough to adjust the relationship.

  5. Add more relationships as needed.

Using relationships in Pivot reports & analysis

  1. Select any table and insert a pivot table (Insert > Pivot table, more on Pivot tables).
  2. Make sure you check the “Add this data to data model” check box.

  3. In your pivot table field list, check “ALL” instead of “ACTIVE” to see all table names.
  4. Select fields from various tables to create a combined pivot report or pivot chart

Example: Category & Gender Sales Report

  1. Add category to row labels
  2. Add gender to column labels
  3. Add quantity to values
  4. and your report is ready!

Things to keep in mind when you using relationships

  • Same data types in both columns: Columns that you are connecting in both tables should have same data type (ie both numbers or dates or text etc.)
  • One to one or One to many relationships only: Excel 2013 supports only one to many or one to one relationships. That means one of the tables must have no duplicate values on the column you are linking to. (for example products table should not have duplicate product IDs).
  • You can add slicers too: You can slice these pivot tables on any field you want (just like normal pivot tables). For example, you can further slice the above report on customer’s profession or product’s SKU size.

Benefits of Data Model based Pivot Tables

Once you have a data model in spreadsheet, you will enjoy several benefits (apart from multi-table pivots that is). They are,

  • Distinct counts: This simple but often tricky to calculate number is easy to get once you have data model based pivot. Just go to value field settings and change the summary type to “Distinct count”. Here is a tip explaining how to get distinct counts in Excel pivots.
  • Measures & DAX: Once you have a Data Model, you can unleash the full Power Pivot features on your workbook. You can create measures (using DAX language) and calculate things that are otherwise impossible with regular Excel. Here is an example of percentage of something calculation with DAX & Data Model, to get started.
  • Pivots from data in other files & databases: You can combine data model with the abilities of Power Query to create pivots from data in other places. For example, you can make a pivot from sales data in SAP with customer data in CRM system. Here is an overview of what is Power Query?
  • Pivots from more than 1mn rows of data: You can connect to very large datasets and make pivots from them with the help of data model. Here is a demo of how to set up data model for 1+mn rows of data.
  • Convert Pivot Tables to formulas: Once you have a data model based pivot table, you can turn it in to a set of formulas. You can access this feature from “Analyze” ribbon. This will replace your pivot with a bunch of CUBE formulas. Here is an overview of CUBE formulas.

Drawbacks of Data Model:

Of course, its not all cup cakes and coffee with Data Model. There are a few drawbacks of data model based pivot tables.

  • Compatibility: Data model & relationship feature is available only in Excel 2013 or above. This means, you cannot create or share such pivot reports with people using older versions of Excel.
  • Not able to group data: In regular Pivot Tables, you can group numeric, data or text fields. But with data model pivot tables, you can no longer group data. You must create another table with the group mapping and use it as a relationship.

Do you use relationships?

Ever since discovering PowerPivot, I kind of stopped using VLOOKUP (or XLOOKUP) for most of my own analysis. Now that relationships are part of main Excel functionality, I am using them even more.

What about you? Are you using relationships & data model in Excel? What cool things are you doing with it? Share your tips with us using comments.

Want even more? Try PowerPivot

If you want even more out of your reports, then try PowerPivot. It is a new feature in Excel 2013 (available as add-in in Excel 2010) that can let you do lots of powerful analysis on massive amounts of data. Here is an introduction to PowerPivot.

    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

  3. Hui... says:

    @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!
