How to export data from a string to a CSV file

Hello,

i do have a string in a Livecycle Designer script object with a couple of rows with different entries divided by a semicolon:

COLUMN1;COLUMN2;COLUMN3
Entry1;Entry2;Entry3
Entry4;Entry5;Entry6

The goal is now to export this string from Livecycle Designer into a CSV file by clicking a button. Is there any solution suggested?

Thank you very much.
