Importing and Exporting Data
Estimated time to read: 1 minute
Exporting Data¶
Data in MongoDB is stored in BSON but is viewed in JSON. When exporting data from MongoDB, the intended use of the data should be taken into account to help define to required export format.
For example:
| Scenario | Export Type |
|---|---|
| Export to a local machine | JSON |
| Export to a different system | BSON |
| Backup cloud data locally | BSON |
Export Commands¶
Data can be exported from the cluster using the following commands, dependant on the required export data type.
BSON¶
mongodump --uri "<<Atlas Cluster URI>>" exports the data in BSON.
JSON¶
mongoexport --uri "<<Atlast Cluster URI>> --collection<collectionName> --out=<filename.json" exports the data in JSON.
Importing Data¶
JSON¶
monogoimport --uri "<<Atlas Cluster URI>>" -drop=<filename>.json imports data from JSON.
See mongoimport for more information.
BSON¶
mongorestore --uri "<<Atlas Cluster URI>> --drop dump imports data from BSON.
URI String¶
A URI with the type srv string is used to connect to an Atlas cluster. For example, mongodb+srv://<user>:<password>@<clusterURI>/<database>
The srv string type is used to establish a secure connection to the cluster.
See Mongo SRV for more information.
