Description

I think the biggest issue is that the text inside of an attribute isn't properly escaped when written to a String, which brings conflict when the text contains dollar signs ($)

That's a big roadblock for me as I can't predict if and when some $ signs may be present in the data

An easy way to reproduce is to take the csv to json template here:

In the first ReplaceText, replace a,b,c,d by a$a,b,c,d (it simulates data that may or may not contain a $ sign)
Launch the flow, you'll see the errors / warning / infinite loop
