CSV to JSON (using html/javascript)

I have a script for browsing for a csv-file, import it into my html-document, and then use javascript to convert it to JSON. Problem is it won't work 100% There are "\ all over the result.
The end result should be an array with objects, like this:

let rawData = [
{
"Time": "2020-04-25 01:08:43.420872",
"Token": 1000,
"Token": 2503,
"Transaction": "Tip",
"User": "momo",
"Note": "wednesday night?"
}
]

My current code is attached as .txt in this job.
