Challenge #22: Identify Values to Aggregate

GeneR
Alteryx Alumni (Retired)

The link to last week’s challenge (challenge #21) is HERE.  

 

This week’s challenge is a little special.  I have mentioned before that as internal users or Alteryx we all do these exercises every week and we started doing this at the beginning of 2014.  There have been a lot of exercises since then and the product has changed a lot of the past few years.   The exercise posted here is exercise #1, the inaugural exercise that we completed internally.

 

In the spirit of that, you will find the workflow will build from top down instead of from left to right, that is the way Alteryx used to work.  For some more fun I would ask that before building the workflow, go to the “About” box from the HELP menu and double click the Colorado flag next to the text “Created in Boulder, Colorado”  after that, the tool icons will change to the original Alteryx tool icons that used to be in the product.  Don’t worry, once you close Alteryx and re-open it the icons will return to normal.

Now for the challenge , this week’s challenge is an intermediate difficulty one that requires parsing a text field to get at values to summarize. 

 

Use case:  The log files from an ATM machine have the transaction amounts embedded in text strings.  The user needs to have these text amounts summarized by row (transaction).

 

Objective: For this assignment the numbers directly following the text ‘ATM2.’ are dollar amounts for transactions. Summarize the values on a row by row basis.

 

Have fun!

 Hi Tara! First time here, was interested if those exercises are aimed at personal training use or people usually submit their solutions here?

Hello @alexey_nikityuk and welcome to our community!  

 

These exercises are for users of all abilities to sharpen their skills and develop new ones. We love feedback and we want to know your experience with the exercise. Every Monday, @GeneR posts a new exercise and a solution for the previous week.  I will comment with a screenshot of Gene's solution in the Spoiler text like this

This is where your screenshot goes!
If you are looking for a forum where the exercises and solutions are posted in a discussion-like thread, vote on the idea submitted here.

Feel free to play along! There are so many ways to solve a problem in Alteryx. We'd love to see how you arrive at the answer!

Hi @TaraM! Yeah, I really liked those exercises and did this one. Was interested if the idea is then to check users' solutions to what you will post next week.  Got it now! Thanks a lot!

Slightly different approach - same number of steps - same result!

Love that easter egg to move this into the old icon format @GeneR

 

took a similar but slightly different approach than @MarqueeCrew 

Spoiler
- Used RegEx to tokenise the ATM2 delimited text into rows - very similar to what @TaraM did using the replace and then text to columns but more direct
... however, had a problem that on row 143 there was no closing ] so had to add this and extend the string length to prevent truncation
From there - just a simple summarise and cleanup
