When using MongoDB, you can use mongoimport to import documents into a collection. mongoimport is a command line utility that imports content from an Extended JSON, CSV, or TSV file. The import file could have been created by mongoexport or some other export utility.
This article presents examples of importing a JSON file into MongoDB.

If you have a view in a MongoDB database that you’d prefer to be a collection, you’re in the right place.
Below is an example of converting a view to a collection in MongoDB.

MongoDB has since deprecated these. Also, starting in version 4.2, MongoDB has removed the copydb command, and therefore also the db.copyDatabase() method, which means that you can’t use them even if you wanted to if you’re using MongoDB 4.2 or later.
Fortunately, there’s another way to copy a MongoDB database.
Continue readingIn earlier versions of MongoDB, you could use the db.collection.copyTo() method to copy a collection.
MongoDB has since deprecated that method. Also, starting in version 4.2, MongoDB has removed the eval command. Given db.collection.copyTo() wraps eval, this means that you can’t use either of them if you’re using MongoDB 4.2 or later.
Fortunately, there’s another way to copy a MongoDB collection.

The mongorestore utility loads data from either a binary database dump created by mongodump or the standard input into a mongod or mongos instance.
There are several ways to back up a database in MongoDB. One quick way to back up a database is to use the mongodump tool.
mongodump reads data from a MongoDB database and creates high fidelity BSON files which the mongorestore utitlity can use to restore a MongoDB database.
With mongodump, you can back up a collection, a database, or all databases.
