Remove LF inside specific field and nowhere else

I have been asked to clean data up in a MongoDB collection we have to stored addresses and generic customer contact data.

Data contains occasionally carriage returns that tend to break the load process when I push the data into a MySQL table. My code uses Javascript to do a replace(/\n//g, '') on the critical fields. However, the data dump still shows up messy as shown here:

The "Note" field is the challenge here. What I run cat --show-all filename, I see the LF "$" character at the end of each record as well as inside the "Note" field.

I tried tr '\n'''<filename but it removes all the LF characters. Is there a way to remove the LF characters only inside the "Note" field?

PS: Raw data file (9 lines) if you want to check for yourself.
