Introducing Data from Hell:
Watch out, its data from hell. In this new video series, we are going to look at some nutty, frustrating and fun data reshaping challenges and solve them using Excel. We will use Power Query, Formulas, VBA or other features as needed to free this data from damnation.
For our first installment, let’s reshape unevenly spaced list of values to a table.
Unevenly Spaced List -> Tabular format
Let’s say you have a list with some values. They are separated by blank cells. You want to convert this to a table, so related values are on same row. But the table can have any number of columns depending on how big the chunks are.
Something like this:
Enter Power Query (Get & Transform Data)
You guessed right. This data is too much out of whack for formula based solution. So let’s reshape it using Power Query aka Get & Transform Data.
The process goes like this:
- Load the data in to query editor
- Replace nulls (blank cells) with something that is not part of your data, like %^%
- Using Text.Combine, concatenate all values to a single value, separated by some symbol that is not part of data, like =
- Convert this single value to a table and split by the symbol used in step 2.
- Calculate number of = symbols in each row using Text.Length and Text.Replace functions in to a new column
- Figure out the maximum of this new column as a variable. Name it as MaxCols
- Remove the extra column created in step 5
- Split the first column by delimiter set in step 3 with number of columns set to MaxCols.
- Load data back to Excel.
Data from Hell – Convert unevenly spaced list to table – Power Query tutorial
As this process requires a bit of tinkering with Power Query functions and a few false starts, I made a tutorial. I woke at 4AM to record this. Just kidding, I woke up because my nose was all blocked up and couldn’t go back to sleep. So I opened up Excel for some play and recorded this. Check it out below.

Ciao Hui,
Collecting Excel tricks under the title “Notable Excel Websites (Non-MVP) Edition” is a brilliant idea…
Thank you in the name of all The FrankensTeam.
On our site there is a box with a picture and text highlighting:
This is a no-MVP site
we think ourselves “bad boys” a bit 🙂
For those who would like to know why our site is a no-MVP site, enough to click on the link:

Thank you again!
Thanks a lot
I really enjoyed this (newsletter). I must admit that I rarely read an Excel newsletter (and I subscribe to quite a few) all the way though, but this grabbed my attention and before I realized it, I was engrossed in it. I must also admit that most of this I don’t understand, yet. But, it excites me when I do learn something new in Excel. I can’t wait to see how much of this I can implement into my (constantly-evolving) ‘House Budget’ & ‘Family Medical’ worksheets that I have developed over the past few years! I sure hope to see more of these type of newsletters in the future! Thanks!
Thanks for doing this Hui! I appreciate being included.
I like Tom’s tip a lot. I posted about a tool I wrote to automate this at http://yoursumbuddy.com/tables-edit-query-dialog/
EXCELLENT !
Hui, This post is Superb! More over I have always been a fan of Roberto’s work and have learnt a lot from him.

I like the Excel Ninja Menus.
1. Select a cell or range then move till the 4-way cross appears. Right-Click and drag the selection to another place in the worksheet then, like a ninja, a menu full of skills and throwing stars pops up allowing me to do all kinds of awesomeness.
2. When you click the fill box on a Date and right click and drag it down, a lot of amazing Date options pop up.
I also brand my Excel to remind myself that I’m awesome. In my personal macro workbook I place the following code.
Private Sub Workbook_Open()
Application.Caption = “SuperKrishna’s Awesomeness”
End Sub
My favorite tip goes along with #17. If you try to copy subtotaled data (and in earlier Excel versions filtered data),when you paste it all the data displays instead of just the summarized data.
To get around this, select your summarized data, click on Find and Select tab and then select Go to Special. Click Visible cells Only and click OK. Now paste and you will see that only the summarized data has been copied.
You can also go CTRL+G and then click the Special icon at the bottom of the dialog box.
What a great idea, Chandoo! I’d love to be included in your next edition:) Perhaps a VBA exclusive version?
@Ryan
I will review this concept about 6 months out from the original post and be sure to keep your site in mind
Hui…
That sounds great, Hui:) I just realized I gave credit to Chandoo for the idea and I should have attributed it to you.
Sorry about that!
