How to Export a Database from MongoDB Atlas

Prerequisites

Ensure you have MongoDB 3.6 or higher, as mongoexport is supported on these versions. The tool is designed to export collections from an Atlas database efficiently without skipping fields.

Using mongoexport

Utilize the mongoexport command-line tool to produce a JSON or CSV export of your MongoDB Atlas collection. This command must be executed from the system command line, not the mongo shell.

Establishing Connection

Connect to your MongoDB Atlas instance using the --uri flag with your mongodb+srv URI. This is the preferred method for a simple and secure connection.

Specifying Export Parameters

When running mongoexport, use the --db option to define the database and the --collection option for the specific collection you wish to export. Specify the desired output path using the --out flag.

Authentication and Security

For Atlas databases, use the --username and --password options for authentication. If additional security is needed, the --sslPEMKeyFile and related options provide encrypted connections. However, be cautious with --sslAllowInvalidCertificates and --sslAllowInvalidHostnames, as they pose security risks.

Filtering and Output Customization

Customize your export with the --fields or --fieldFile options to include specific fields. Use the --query option to filter documents. Determine the output file type with --type and control the order and number of documents with --sort, --limit, and --skip options.

Backing Up Data

While mongoexport is useful for exporting collections, it is not a full backup solution. Use mongodump for creating backups of M0 free clusters and rely on Atlas's native backup capabilities for M10+ and serverless instances.

Frequently Asked Questions

How can I export a single collection from MongoDB Atlas to my local machine?

You can use MongoDB Compass to export a collection as a JSON or CSV file. Alternatively, you can use the mongoexport command to export a single collection.

Can I export all collections from MongoDB Atlas at once?

Yes, you can use the mongodump command to dump all collections at once.

How do I ensure that I only export certain documents from a collection?

You can use a query filter with MongoDB Compass or the mongoexport command to export only the documents that match the filter.

Are CSV files a good option for backing up my MongoDB Atlas data?

CSV files may lose type information and are not suitable for backing up data. It's better to use JSON format or other methods like mongodump for backups.

How can I specify which fields to export from a collection in MongoDB Atlas?

In MongoDB Compass, you can use the Project field in the query bar to specify the fields to return or export. With the mongoexport command, you can specify fields using the --fields or --fieldFile options.

Common Use Cases

• 
  Migrate data from MongoDB Atlas to another database system
• 
  Create backups of current database state for disaster recovery
• 
  Analyze data offline or with external tools not supported by MongoDB Atlas
• 
  Share datasets with external stakeholders or collaborators without providing direct access to the live database
• 
  Transfer data to a localized environment for development and testing purposes
