How to export JSON from MongoDB using Robomongo

Question

So I do not know much about MongoDB. I have RoboMongo using which I connect to a MongoDB. What I need to do is this - there is a collection in that Mon

Answer 1

Using a robomongo shell script:

//on the same db
var cursor = db.collectionname.find();

while (cursor.hasNext()) {
    var record = cursor.next();   
    db.new_collectionname.save(record);
}

Using mongodb's export and import command

You can add the --jsonArray parameter / flag to your mongoexport command, this exports the result as single json array.

Then just specify the --jsonArray flag again when importing.

Or remove the starting and ending array brackets [] in the file, then your modified & exported file will import with the mongoimport command without the --jsonArray flag.
