I really needed this practice in data parsing. Day by day i'm learning this syntax better

Solution attached,

 

Real nasty one this one, didn't think it was worth making anything re-useable, just got what I needed.

 

There's a video about the Alteryx Analytics gallery where someone (can't remember his name) talks about including some python date parsing tool. Sounds cool, didn't have time to hook it up but would have been nice to see it here.

 

Thanks,

 

Michael

I had to go back to school on RegEx before even attempting this challenge - my result is attached

First time posting a challenge. I knew nothing about RegEx walking into the challenge. I reviewed various solutions, comments, and my friend, Alteryx Help Center. I normally wouldn't share since I did not solve this on my own. However, I learned a lot through this, so I was able to figure out a slight variation with my RegEx Expression. I got excited!  :)

Solved, although the dates remain in "field1" (also in the proposed solution so I'm keeping them...)

I used regex to extract the dates, then the datetime parse tool to tidy up - I learned that you can use a wildcard * in the datetime parse tool which is pretty nifty!

Regex used was  \d{1,2}\-\w+\-\d{2,4}   | (or)   \d{1,2}\s\w+\s\d{2,4}     | (or)   \w{3}\s\d{1,2},?\s\d{4}

Much more brute force than i would have liked. too bad there is no date/time detector.
