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.

    This borders on Excel soft-cell...er, soft-core...porn. My favorite kind.

  2. Tim says:

    Wow, that is pimp-TASTIC! I have a question, as a VBA n00b: additional comment boxes stay plain unless I "run" the macro. Is there a way to change all comments, going-forward?

  3. laguerriere says:

    hi Chandoo, well, I like the macro approach. For those who don't like it, there is another way: just add the "draw" toolbar to the shapes toolbar (via Custom etc), click on "edit comment", click on the auto-shape and then choose "draw" drop-down, --> modify auto-shape --> then you even can have a heart or a banner (I like the horizontal banner in in purple :-)) . in excel 2007, you have to add this custom menu that you choose via Excel Options --> Custom --> it is called "change/ modify auto-shape"!!!
    best,

  4. Tom says:

    @Chandoo. Great Post 🙂
    @Tim : the way the macro is coded, it must be run very time.
    @Community: If someone has an idea to perform it when opening an existing excel, it should be nice.
    @Community: if someone has some code to revamp the commentboxes on all sheets, please share it. 🙂
    @Microsoft Excel-progammers: some pimpoptions for the commentboxes should be great.

    Cheerio

  5. Yukikomi says:

    For the auto run, please add the codes in workbook:

    Private Sub Workbook_SheetActivate(ByVal Sh As Object)

    Call Comments_Tom

    End Sub

  6. Debra says:

    Wow, that was a lot of fun... Thanks Tom!

  7. Chandoo says:

    @Jeff... Now, 5000 people know about your favorite porn... 😛

    @Tim ... you can write an event to handle the new comments. I wouldnt recommend it as it is really painful. another option is to use the macro suggested by Yukikomi. It will update comments everytime you activate the sheet.

    @laguerriere: very cool 🙂

  8. Johnnie says:

    @Chandoo ... Thanks! This is good stuff. I combined your tip with a tip from Mark O'Brien, then assigned it to a button on Excel 2010's Quick Access Toolbar, to format comments AS I add them. I also like how Mark's code saves me the trouble of backspacing my name out of new comments:

    Sub AppendToExistingComment()
    'Source: Mark O'Brien at http://www.mrexcel.com/forum/showthread.php?t=57296
    Dim oRange As Range
    Dim oComment As Comment
    Dim sText As String

    'Use object variable to hold range.
    Set oRange = ActiveCell
    'Use object variable for comment
    Set oComment = oRange.Comment
    'text to be added to the comment box
    sText = InputBox("Type text to be added:", "APPEND TO COMMENT TEXT")
    If Len(sText) = 0 Then End
    'If Active Cell has a comment then append new text to the end of the comment text
    If Not oComment Is Nothing Then
    sText = oComment.Text & vbNewLine & sText
    oRange.Comment.Delete
    End If

    'Add a comment with the contents of sText
    oRange.AddComment sText

    DoEvents
    Comments_Tom

    End Sub

  9. Nick says:

    Thank you very much for the code, it seems to be working for the most part; I am having a problem however. Once the routine makes the corrections to the comment, the comment becomes invisible. By invisible, I mean that when I highlight my mouse over it, nothing appears. However, when I right click the cell and click 'edit comment' then the comment becomes visible and I enter edit mode. Upon clicking out of the comment, it simply vanishes again. I've tried to fix this problem by adding a .shape.visible = msoTrue but then every comment is always visible. o_O please advise...

    Thank you,

    Nick

  10. Shailyog says:

    @Nick- That is because the font color of the comment is white and when you select the color of selection is also white hence you can not see anything. Try to change the color code in the routine to something else. would work

  11. Michael says:

    Thanks for that! The code works perfectly!

  12. [...] look at Format Excel Comment Boxes using VBA Macros | Chandoo.org - Learn Microsoft Excel Online [...]

  13. Sunny says:

    @ Chandoo - code works great and the comments look super cool. But I have ran into a small issue. In the comments, I am inserting pictures. When I run the macro, for all comments which already have pictures; pictures are deleted. Pls help me retain the pics in comments.

  14. […] posted some code one of his readers submitted, it "pimps" your comment boxes from those boring black-text-on-yellow rectangles to something more professional and eye-pleasing. […]

  16. Deepak says:

    Hi Tom,

    This looks really excellent. I am however relatively new to macros / VBA codes so having copy pasted your code in the Developer mode of an Excel file, what are the next steps to use them? Can you please help? Just to recap, I opened a blank Excel workbook, clicked on Developer, copy pasted the comments code and saved the file to the desktop.

    Now how do I go about using it to add comments to an existing file? My apologies for asking a question which may be basic to you great geniuses, but I am not there yet and aspire to get there.

    Many thanks for helping me with next steps that I need to take so that I can now use the code.

    Best Wishes

  17. Tom says:

    Dear Dave,

    The best thing to do is to copy the macro in the personal.xls(x) file. The personal excel file will always be launched when you open excel so you can use it with every excelworkbook.
    Read all about it on the page of Microsoft.
    https://support.office.com/en-us/article/Copy-your-macros-to-a-Personal-Macro-Workbook-aa439b90-f836-4381-97f0-6e4c3f5ee566

    Once you have the macro in the personal, you can 'call' the macro by the keyboardcombination 'alt+f8' and klik on the macroname.

    Hope this clarifies the 'how to'. Good luck with your first steps in the wonderfull world of macro's.
    Tom

      Hi Tom,

      Many thanks. I will try that out. Learning is fun and learning this stuff is even more amazing.

    There is a line 'Dim LArea As Long' which does not appear to be used. Have I missed something?

  19. Luis says:

    Excellent hack!
    For some reason when I opened my file after using LibreOffice Calc, all comment boxes had changed to some arrow shape.
    So this macro helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.
    I used it with the following attributes to get back old style comments:

    It helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.

    .Shape.AutoShapeType = msoShapeRectangle
    .Shape.TextFrame.Characters.Font.Name = "Calibri"
    .Shape.TextFrame.Characters.Font.Size = 10
    .Shape.TextFrame.AutoMargins = True
    .Shape.TextFrame.AutoSize = True

    Thanks a lot!

    I think this is among the most significant
    information for me. And i am glad reading your article.
    But wanna remark on some general things, The site style is great,
    the articles is really great : D. Good job, cheers

  22. Jen says:

    Is there code to add to this that will format a particular part of the comment (i.e. make the last sentence in the comment bold and in italics)?

  23. Phil says:

    This is fantastic!
    How would I add auto-sizing to it?
    I tried adding this:
    .Shape.AutoSize = True but it gives me an error and as a novice at VBA I can't figure it out.

    This is GREAT!

    How should the code be changed in order to tun once for all worksheets in a workbook?
