Problem is that in a CSV file, CRLF duo are used to separate the lines. The problem here is to known when it is a end of line CRLF and a end of line in your "message" field.

Your best bet would be to replace your CRLF inside your "message" field by any other string like {CRLF}, in Workflow using Regex and then use my solution in PPress.

Here is how I did it:

1. steps up to here
2. Advanced Search and Replace using REGEX (explanation below)
3. Advanced Search and Replace using REGEX (explanation below)
4. Advanced Search and Replace using REGEX (explanation below)
5. steps continue

So, I used REGEX:

In step 2., I used:
-String to search = "(\r\012)
-Replace with = "{goodCRLF}
which replace the end of line CRLF by {goodCRLF}

In step 3., I used:
-String to search = (\r\012)
-Replace with = {CRLF}
which replace the end of line CRLF, from the "message" field by {CRLF}

In step 4., I used:
-String to search = \{goodCRLF\}
-Replace with = \n
which replace the end of line {goodCRLF} from earlier back into a end of line

and then that works with my previous PressTalk
