Weekly Challenge Index & Welcome

[JoeM]

Welcome to the Weekly Challenge. Each week we will post a use case where you can put your Alteryx skills to the test. You'll be able to share your answers and collaborate with other challengers to arrive at an answer. Participation will be rewarded - just make sure you are attaching your Alteryx workflows to your responses!

This is ridiculously helpful - thank you @JoeM. 🙂

Hope it's not too much of a pain to maintain - since it provides such a useful single-stop place to reference these exercises without having to search all the various posts on the board.

[ErikaW]

Thank you, @JoeM! So helpful!

[Subratdas]

This is a very helpful list.  Thanks a lot for taking the effort.

I have been unable to open the start files for most challenges since week 61. In my Corporate environment we are on Alteryx 10.5.9, and we have no option to upgrade until our corporate IT department decides it is ready.

Could the challenge start files be posted in a format that can be opened with 10.5?

[JoeM]

@PaulRB,

I have updated everything since challenge 61 so it can be compatible with your version of Designer. If you ever run into version issues with any workflows on Community - check this article that shows how to make workflows compatible with your version.

[PaulRB]

Thanks JoeM!

[SeanAdams]

Hey @JoeM - thank you for our weekly dose of brain-candy - gonna tackle #68 now!

How would you feel about gathering the good folks at Alteryx, to come up a weekly challenge that forces us to use some of the tools that are languishing in the toolbox just waiting to be invited to this great party?   Something slightly mean, that makes people have to have a second (and perhaps even a third) coffee before they can get through it?

I'm thinking, for example, of setting a challenge that requires the use of the Calgary tools, or even some of the developer tools (perhaps there's something fiendish that the team could come up with to force the community to engage with all the Blob tools under the developer tab), or if you wanted to be really mean then perhaps the XML extensions to functions?

🙂 Thank you again for the work that goes into this Joe - it really is one of the most useful ways for me to learn, and I know that a lot of people feel this way!

Have a good Tuesday

Sean

Seriously though, I have some sitting around that we could use. However, we have some challenges coming down the pipe from "Big Data" Matt (@MattD) this May , so I can start throwing out some more difficult ones in June!
