Question

How do you export all the records in a MongoDB collection to a .csv file?

mongoexport --host localhost --db dbname --collection name --type=csv

I could not get mongoexport to do this for me. I found that,to get an exhaustive list of all the fields, you need to loop through the entire collection once. Use this to generate the headers. Then loop through the collection again to populate these headers for each document.

I've written a script to do just this. Converting MongoDB docs to csv irrespective of schema differences between individual documents.
