Making sure all fields are covered

json2csv will buffer all objects to make sure no fields are missed before spitting out the csv. If you know what fields you want you can avoid buffering everything by passing in an -f option:

$ mongoexport -c users > users.json 
$ <users.json json2csv -f fielda,fieldb

json-fields

This utility simply spits out all of the fields from a stream of JSON objects
