RegEx to add a space after a comma

@DavidAD, you can add a second regex action that replaces the commas (,) with a comma and a space (, ). This can be added before or after the original setup, as the one referenced in the link is just removing the brackets and quotes. I did a quick test taking the output from the first action with output of Choice 1,Choice 2,Choice 3 running the replace on , and this seemed to get the desired output. 

Output:

By Jove, @burked, you've done it again! That does indeed work. Thanks very much! That's simpler than I expected.

​@burked: Unfortunately, this no longer works. If you add a space after the comma in the Replacement text field, Nintex Workflow removes it automatically. I was actually using a semicolon in that field, but I tried a comma too and the result was the same. Now we’re back to this after removing the brackets and quotation marks:

Option 1,Option 2,Option 3

Nintex Workflow used to add a space automatically after the default comma in a collection. That stopped working, so the above solution was useful. Now that solution is no longer working. Is there another solution for adding a space between items in a collection? I’m needing it for a new workflow I’m developing now.

Hi, ​@SimonMuntz - thanks for the prompt reply. And yes - I do believe that would work! Thank you. I never would have thought of extracting the characters like that.

I developed a different workaround for my current use case that actually works better (adding each item from the collection to a table on a generated document), but I will certainly use this in the future.

Thanks again!
