Compass Export Database Guide

Exporting Data from Collections

To export data from a MongoDB collection using Compass, select the desired collection from the Databases tab or use the left-side navigation to click the collection. Compass allows you to export data as JSON or CSV files, but it is recommended to export in JSON format to maintain type information.

Using Query and Projection Filters

Utilize Compass's query filter to export only the documents that satisfy specific criteria. Incorporate the Project field in your query to specify which fields to include in the export. This ensures that only the relevant documents and fields are exported.

Exporting Data with MongoDB Database Tools

For command line operations, use MongoDB Database Tools. The mongoexport command allows for data exportation directly from the command line, providing an alternative to the Compass GUI.

Step-by-Step Export Process

Navigate to the detailed collection view in Compass to start the export process. Remember, importing data into a collection is not available in the Readonly Edition of MongoDB Compass. Exporting to CSV files is not recommended due to the potential loss of type information.
