So I read and read and still couldn't find anything that would use most all of the supported date formats and auto detect which to use and then convert that to a date. I found one article that did it for 4 date formats, but I wanted it to be able to handle 50+... I think there were some python libraries that would do it, but I needed it to be native Alteryx. So... I took a stab at it. It might not be the most elegant, but the attached macro will automatically detect most any date format and convert it to a standard YYYY-MM-DD date. Now, of course, it has to choose dd vs mm first... so I defaulted to mm/dd/yyyy over dd/mm/yyyy as long as it was an eligible date (US preference). I guess that could have been a parameter into the macro. Feel free to improve and post back here!
Enjoy!
