            I'm using json2csv v5.0.6 for a small project and I wanted to format some values using custom formatters so I get a clean CSV file.

            However, I can't seem to make the formatters work. I have one number formatter and one string formatter that are supposed to be called upon parsing. Here's a sample test file that reproduces this behaviour, with two simple formatters:

            You have to use the alpha version : json2csv@6.0.0-alpha.0

            The last released version has some issue with formatters : https://github.com/zemirco/json2csv/issues/521 (they are not exported)

            And you also have to call your formatters functions

            Use jq -f json2csv instead.

            From man jq:

            -Ldirectory / -L directory:

            Prepend directory to the search list for modules. If this option is used then no builtin search list is used. See the section on modules below.

            Compare this to:

            -f filename / --from-file filename:

            Read filter from the file rather than from a command line, like awk´s -f option. You can also use # to make comments.

            You can achieve all these things in your single file app.js file. We need to have json2csv module because this module has the parser class so that we can use parse() method to get the CSV format data as String. Here lean options tell mongoose to skip instantiating a full Mongoose document and just give you the Plain Old JavaScript Object POJO. And also I have used username and password as documents so change it accordingly.
