Export MongoDB query to CSV

Jump to


    Welcome to the ultimate guide on exporting MongoDB queries to CSV files. Understanding how to efficiently convert your database queries into a versatile format like CSV is crucial for data analysis and reporting. A CSV file can easily be loaded into spreadsheet software, allowing for a familiar and accessible view of your data, which is invaluable for data interpretation, sharing, and collaboration. On this page, we'll delve into the intricacies of MongoDB queries, guide you through the process of exporting these queries to CSV files, explore the practical use cases for such exports, introduce Sourcetable as an alternative method for converting JSON to CSV, and answer your most pressing questions about the entire process.

    Exporting MongoDB Query to a CSV File

    Using mongoexport Command-line Tool

    To export data from a MongoDB database to a CSV file using the mongoexport command-line tool, you must have read access to the target database. Run the mongoexport command from the system command line, not from within the mongo shell. Ensure that you specify the fields to export using the --fields option or list them in a file and use the --fieldFile option. To filter the data that you want to export, utilize the --query option with a JSON document representing your query. If you prefer not to include the field names in the first row of the CSV, add the --noHeaderLine option. Finally, direct the export to a specific file using the --out option.

    Specifying Fields and Query Filters

    When exporting to CSV format, it is mandatory to define which fields to include. Do this with the --fields option followed by a comma-separated list of field names, or use the --fieldFile option to indicate a file that contains the list of fields. To export only a subset of the data that matches certain criteria, provide a JSON document as the argument to the --query option. This specifies the query that mongoexport will use to filter the documents included in the export.

    Setting the Export Format and Output

    Make sure to set the file type to CSV when performing the export by using the --type option with the argument 'csv'. After specifying the fields and the query, if required, set the destination file with the --out option, where the CSV data will be written. To write the entire export as a single JSON array instead, use the --jsonArray option, but this is not applicable for CSV exports.

    Adjusting Read Preferences and Document Limits

    By default, mongoexport operates with a read preference of 'primary'. If necessary, you can override this with the --readPreference option followed by your preferred read preference. Additionally, you can control the starting point of the export with the --skip option and limit the number of documents exported with the --limit option.

    Connecting to the Database

    To connect to your MongoDB instance, use the --uri option with the necessary connection details, such as host, port, username, and authentication database. Alternatively, you can provide these details through individual options like --host, --port, --username, --authenticationDatabase, --collection, --db, and --password. For AWS-hosted databases, you may also need the --awsSessionToken option.

    Frequently Asked Questions

    How do I export data from MongoDB to a CSV file using mongoexport?

    Use the mongoexport command-line tool from the system command line (not the mongo shell) with the --type=csv option. Specify the fields you want to include with --fields or --fieldFile. Use --query to filter the data and --out to specify the destination file.

    Can I export only specific fields from my MongoDB query to CSV?

    Yes, use the --fields option with the --type=csv to specify individual fields, or the --fieldFile option to specify a file that contains the list of fields you want to export.

    How can I export data from MongoDB without including the header line in the CSV?

    Use the --noHeaderLine option along with --type=csv to export the data to a CSV file without including the list of field names at the top of the file.

    Is it possible to export data from a remote MongoDB instance?

    Yes, you can connect to a remote MongoDB instance by using connection options like --host, --port, --username, and --authenticationDatabase, or simply use --uri to specify the complete connection string.

    How do I ensure that my mongoexport command only exports the results of a specific query?

    Use the --query option with a JSON-formatted query enclosed in single quotes to filter and export only the documents that match your query criteria.


    In summary, exporting a MongoDB query to a CSV file is a straightforward process that can be accomplished using the mongoexport command from the system command line, which requires specific options like --type=csv and --fields to define the export format and content. However, it is important to note that while the mongoexport command facilitates the export of data to a JSON or CSV file, it does not support aggregation operations and is not run from the mongo shell. For those looking for an even more efficient way to work with their data, consider using Sourcetable to import data directly into a spreadsheet.
