How to format plain text line breaks into html or something that doesn't break my json?

use case:

• I have a webform sending plaintext data to a trigger my zap (webhooks by Zapier). 
• I need to put that plaintext into the json body of an API Request for another system 
• the webform has 8 plaintex fields

Issue:

• the webforms fields are large text areas, allowing for someone to insert a line break. 
• the line breaks are messing up my json body for the API request

API request format:

{
"title": "title text from webform",
"content": "description text from webform"
}

What’s happening with the line breaks

{
"title": "title text from webform is working great (no line breaks)",
"content": "description text from webform is ruining things
because of this line break you see here"
} 

If you put that into an online JSON Validator, you can see that the line break is breaking the string and ruining the key/value pair (did I use that right?) of “content” with the “{data from twebhe form}”, thus breaking the json formatting. 

Question 1: So I know the problem, but what solutions do I have? 

I’ve been playing around with the Formatter, but not having a lot of luck. 

• There are not actual line break characters to replace

• The plaintext is not in markdown, so transforming from markdown to html doesn't’ give me the breaks 

  

   

• URL encoding is the closest i’ve gotten yet to creating an unbroken string, but i’m still running into to errors with my tests

Question 2: Is there a way to format 8 different fields in one or two steps? 

Let’s say that it can be solved by URL encode or something like that… do I have to add a formatter step for each field, or is there a way to format the initial webhook payload in fewer steps?
