Parsing Name with RegEx

[alexg1]

Hello everyone,

I've got a list of names that are stored like so in a dataset:

     JohnAdams

And I need to parse them to get this:

     John Adams

The names are variable in length, so I do not know of a formula that would accomplish this result. The First and Last names are all correctly capitalized, so if there is a way to parse by case, I think that would work.

Thank you for your time

Hi @alexg1,

Try a Formula tool with the following:

REGEX_Replace([f1], "([a-z])([A-Z])", "$1 $2", 0)

...where [f1] is the field in question.

Explanation:

Parentheses in a RegEx will "mark" any match, and these are counted starting at 1.

With this expression, we therefore match any lower-case letter, which is $1, followed by any capital letter, which is $2.

That match will be replaced by $1, a space, then $2... giving you the space you wanted.

The final 0 argument at the end tells Alteryx to respect the case of the input; (ignoreCase = 0 or false)

Hope that helps!

John

That worked perfectly, thank you! I appreciate you going through the underlying logic as well, RegEx syntax is a bit daunting for neophytes!
