How to use Excel Data Model & Relationships

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.

Table relationships & Data model feature of Excel - cartoon

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.
    Adding a pivot table with data model in Excel 2013
  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.

Click here to download Excel data model demo file. It contains 3 different tables and a combined pivot report (with slicer) to show you what is possible.

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.

    Hi Chandoo,

    Since this article was for Dates, below are 2 easy ones to calculate the Start and End of Month. (without using the EOMONTH formula as available in Analysis Toolpak).

    In Cell A1, put any date
    then in the cell where you would want the Start of Month put the below formula
    1. Start of the Month
    =DATE(YEAR(A1),MONTH(A1),1)

    2. End of Month
    =DATE(YEAR(A1),MONTH(A1)+1,0)

    Hope this would help a lot who were dependant of EOMONTH..

    cheers

    I know how to write macro's for excel, but I have 1 issue that I cant figure out and would appreciate some help.
    I want to key a range of dates, (7/1/09-7/12/09) then write a macro to go find the info for that range and bring it back to my spread sheet.

    Thanks for any help....

  6. Chandoo says:

    @Glenn: you can try a user defined function if the information you want to gather can be derived only from the 2 dates entered. You can write a macro, if you need to refer to other ranges in the workbook to gather the info based on the dates entered. I am not sure what you meant by "go find the info for that range". May be if you tell what you are trying to find, I can suggest the approach for writing a macro...

    talking about dates, therz a formula that i use very frequently to calculate the difference between two dates.
    its not documented in 2007 though

    =DATEDIF(START_DATE,END_DATE,"Y") - gives you the years
    =DATEDIF(START_DATE,END_DATE,"YM") - remaining months
    =DATEDIF(START_DATE,END_DATE,"MD") - remaining days

    im sure you'll know this. wonder why it isnt documented. works fine with 2003 and 2007

  10. Ray Solanki says:

    Help please... I have two dates eg: 1/8/10 - 10/8/10 and i would like to know the number of Fridays and Mondays in any given period

  11. Hui... says:

    Ray

    Try the following user defined function:
    ===

    Function NoMonFri(uStart As Range, uEnd As Range, Optional uType As Integer) As Double
    Count = 0
    For i = uStart To uEnd Step 1
    If Weekday(i) = 2 Or Weekday(i) = 6 Then Count = Count + 1
    Next i
    If uType = 1 Then
    If Weekday(uStart) = 2 Or Weekday(uStart) = 6 Then Count = Count - 1
    If Weekday(uEnd) = 2 Or Weekday(uEnd) = 6 Then Count = Count - 1
    End If
    NoMonFri = Count
    End Function

    ====
    Copy the above into a Code Module
    To use just enter
    =NoMonFri(A1, A2) or
    =NoMonFri(A1, A2,1)
    Where A1 & A2 are the Start and End Dates (inclusively)
    The use of the optional 1 will Exclude the Start and End dates

  12. Chandoo says:

    @Ray... You can also do this using SUMPRODUCT (ahem)

    Assuming first date is in C6 and second date is in C7,

    =SUMPRODUCT(--(MOD(WEEKDAY(ROW(INDIRECT(C6&":"&C7)),2),4)=1))

    Will give you the number of Mondays and Fridays between C6 and C7 (including both days)

    Also, checkout NETWORKINGDAYS() UDF for more complicated counting... http://chandoo.org/wp/2009/06/09/networkingdays/

    Hello Chandoo,

    How to convert no into time. for ex: 3600(In Seconds) into 1:00:00

    Thanks,

    Chandra Shekar B

  16. Hui... says:

    @Chandra
    Times are a fraction of 1
    So 6am is 0.25
    12 noon is 0.5
    6pm is 0.75
    So convert hrs and mins to a fraction of 24 hrs
    1 Hr = 1/24
    3600 seconds = 3600/(24*3600)
    etc

    Hi Chandoo,

    When discussing about time.. I have one question too. Basically, I have one sheet in which we enter "Shift IN" & "Shift OUT" times as "hh:mm" format in A and B columns and next columns C & D pulls the scheduled and present count of agents from other sheet by VLOOKUP-ing times as

    IN time (hh:mm) - OUT Time (hh:mm). For eg; 03:30 - 12:30

    Columns A and B have been validated to accept only values between 00:00~23:30 (half hour intervals). and when pasting data, the values are usually accepted and I don't get any errors of validation.
    But, when performing vlookup to get the number of scheduled agents say as of the time interval 03:30, I get an #N/A error. I have confirmed ranges are all fine, but what I found is that the time although shows same but they are actually of different days. Say for eg;

    41023.39583 gives 9:30
    41024.39583 gives 9:30 too..

    Validation is accepted as time is same, and it works fine if I select the time interval from the validation list. So, was wondering, if I can select the same interval from the list using VBA.. so that whatever the time intervals gets updated, I just need to run a macro to automatically select the interval from the validation list.. I have come across that we can use Cell.Validation.Formula1 in some manner to get the item from list.. but it would take the number of the item in the list.. wondered if I could get the item through text. Any ideas to accomplish this task?

    Regards,
    Avinash

    Chandoo,

    Please i need an advise ASAP i have been using this statement and it cant help

    if(and(c1>=a1:a144,c1<=b1:b144),"yes","no"))

    and it just works for the first 2 values c1, c2 and doesn't fit for the others.
    the case is i have more than one event at the same video and i need to confirm that no event was taken unless it is between start and end.

    here are some samples:

    Start dtime End Dtime Event Dtime
    16/09/2013 22:13:34 16/09/2013 22:14:18 16/09/2013 22:13:38
    16/09/2013 22:15:57 16/09/2013 22:24:30 16/09/2013 22:16:02
    16/09/2013 22:24:30 16/09/2013 22:33:49 16/09/2013 22:17:32
    16/09/2013 22:33:53 16/09/2013 22:35:05 16/09/2013 22:19:02
    16/09/2013 22:35:05 16/09/2013 22:39:57 16/09/2013 22:20:02

    So as you can see there are more than one event between one start and end dtimes

      @Jenny
      It is poor practice to store multiple records in one cell
      It is much easier to store multiple records ion multiple rows
      That also allows flexibility in reporting

      When entering data in a record that is mostly similar to the record above, you can use the Ctrl+D shortcut, This duplicates the cell directly above you speeding up data entry

    Hello,
    Could you please tell me the solution to this? I have spent months, years, looking for it...
    When I press ctrl+; to enter the date in a cell, I want it to enter d/M/yy. My short date in windows regional settings is d/M/yy. Excel enters d/M/yyyy. The cells must be formatted as text they cannot be formatted as date. I do not want to have to macro-enable my workbooks, There must be a setting in the registry to set this?

    Alternatively, how can I assign that key to my own shortcut for a macro to enter NOW with custom date format? Can't find that either!
    I hope you can help!
    Many thanks

    and cell b1 has working duration i.e. 7 hours . it shows in cell C3 04/02/2017 19:30:00 but 19:30:00 is not our working time. i want to show the value of plan date as 05/02/2017 11:30:00 . working time id 09:00:00 to 17:00:00

    Hi Chandoo!
    I export incident data daily to Excel 2016 and the dates are text (e.g. 8 Apr 2018). I changed cell to short date field format, but it still recognises this as text until I 'F2' then 'Enter' in each cell. Is there a more efficient way to do this; I have 3 columns of dates and about 1000 lines of data.
    I need it to be dates so I can then create pivot tables and charts from the data.
    Many thanks,
    Kirst.

    some things I find useful:

    INT this will give you the date part of a datetime field
    MOD this will give you the time part of a datetime field

    if you had

    21/06/2018 10:25:00

    in cell a1

    then =INT(A1) would give you 21/06/2018
    and = mod(a1,0) would give you 10:25:00

    oSUM!

    The most important thing is if you do any calculations you need to be careful, given the vagaries of floating point math.

    e.g. depending on the day you choose, 4pm minus 3pm may be less than, equal to, or greater than one hour.

    Results in some infuriatingly subtle bugs when you forget!

    Wow! Came here from India's top blogs and this is superb! For some reason, dates have always confounded me in Excel and this was exactly what I needed - esp the section on adding and subtracting dates. Thanks a ton!

    Hi,

    I have a mixed combinations of date format in one column i.e. 'dd/mm/yy' and 'mm/dd/yy'. How do I make them all in the same format, either all in 'dd/mm/yy' format, or all 'mm/dd/yy' format? Thanks in advance!

    Hi Chandoo,

    Need a small help to build a formula where we can show the date of Monday i.e. start of week date from time stamp for eg "3/2/2022 9:21 PM" or either from "Week 10'2022" where Week is for entire year i.e till week 52/53 and "2022" represents the year

    Thanks in advance

    Best
