Challenge #34: Date-Time Formatting

Highlighted
Alteryx Alumni (Retired)

Here is this week’s challenge, I would like to thank everyone for playing along and for your feedback.  The link to the solution for last challenge #33 is HERE.  For this chalenge let’s look at creating a macro from scratch.  I recommend you first solve the problem with tools on the canvas, then cake a macro from the tools.

 

Use Case:  Our customer has a need to convert date/time strings into a date-time format.

 

Examples of the different input formats include:  4/8/2015 4:00, 5/10/2015 13:00.  The conversion is automatic when the hours are 2 digits (10-24), but it ignores hours 1-9 (creates NULL values on conversion).

 

Objective:  Create a macro to effectively convert and preserve the data in a date-time format.

I think that this is straight-forward (after finding the reverse update).

My solution.... in a single formula!! This might be the first time I've had a one-tool solution!! :)

Formula Tool = DateTimeParse(Left([date_time],FindString([date_time]," "))+" "+PadLeft(Substring([date_time],FindString([date_time]," ")+1,8),5,"0"),"%m/%d/%Y %H:%M:%s")
