Export Firebase to CSV
Overview
Welcome to our comprehensive guide on exporting Firebase data to a CSV file - a valuable process for anyone looking to leverage their data outside of the Firebase ecosystem. By converting Firebase data into a CSV format, users can easily import their information into spreadsheet applications such as Microsoft Excel and Google Docs, facilitating a wide range of tasks from data analysis to feeding machine learning algorithms. On this page, we will delve into the essence of Firebase, step-by-step instructions on exporting data to CSV files, practical use cases for such exports, an alternative method utilizing Rowy for those seeking a low-code solution, and a helpful Q&A segment to address common inquiries about the export process.
What is Firebase?
Firebase is a set of cloud-based development tools designed to help developers build, deploy, and scale mobile apps efficiently. It provides a host of features such as Authentication, Realtime Database, Cloud Messaging, Crashlytics, Performance Monitoring, and Test Lab to cater to app development needs. As an app development platform, Firebase not only assists developers in creating apps but also plays a crucial role in growing their user base and engagement levels.
Backed by Google and trusted by millions of businesses, Firebase is a robust platform that enables personalization of the onboarding flow for users, enhancing their overall experience. It also offers capabilities to seamlessly introduce new functionalities into existing applications, ensuring that apps remain up-to-date and competitive in the fast-paced tech landscape.
Firebase Extensions further streamline the development process by automating tasks and adding pre-packaged functionality to apps or projects. To manage these extensions, users must have the appropriate roles, such as Owner, Editor, or Firebase Admin. Although extensions require the Blaze (pay as you go) plan for installation, they can be tested using the Extensions emulator beforehand. Official Firebase extensions, developed by Firebase and partner services, ensure reliability and security, and their source code is available for review. These extensions, which can be browsed in the Extensions Hub, create new, instance-specific resources within a project, which are removed upon uninstallation. Meanwhile, Early access partner extensions are available through a separate program and provided without warranty.
Exporting Firebase Data to a CSV File
Initial Setup
Before exporting data from Cloud Firestore, ensure that billing is enabled for your Google Cloud project, as managed export and import services require it. You must also verify that the Cloud Firestore service agent has the appropriate permissions set by updating the Cloud Storage bucket permissions. The service agent for Cloud Firestore is distinct and more secure than the App Engine service account and is identified as service-PROJECT_NUMBER@gcp-sa-firestore.iam.gserviceaccount.com.
Exporting Data for Offline Processing
To export data from Cloud Firestore for offline processing, utilize the Cloud Firestore managed export and import service. This service will allow you to export all documents or specifically chosen collections. Keep in mind that each document exported will incur one read operation, which will be charged accordingly.
Exporting Specific Collections
If you plan to import only specific collections or load data into BigQuery, ensure to export only those specific collections. This targeted approach helps manage costs and streamlines the import process or the integration with BigQuery. Remember that exporting subcollections requires explicit specification, as they are not automatically included when exporting their parent collection.
Loading Data into BigQuery
To load Cloud Firestore exports into BigQuery, use the export service with a collection-ids filter. Be aware that BigQuery has a limit of 10,000 columns per table, and maps fields may be treated as bytes if this limit is surpassed. Cloud Firestore export operations generate a BigQuery table schema for each collection group, considering unique field names within a collection group as schema columns.
Handling Export Operations
During the export operation, be cautious as the export may include changes made to the data while the operation is running. If the export operation is initiated and you need to cancel it, be aware that closing the terminal may not effectively stop the process. You can view the progress and a list of all export operations in the Import/Export page of the Google Cloud Platform Console.
Metadata and File Format
Cloud Firestore exports data in the LevelDB log format and creates a metadata file for each collection group, named ALL_NAMESPACES_KIND_[COLLECTION_GROUP_ID].export_metadata. These metadata files are protocol buffers and can be decoded using the protoc protocol compiler.

Frequently Asked Questions
How are read operations charged when exporting data from Firebase to CSV?
Exporting data from Cloud Firestore incurs one read operation per document exported.
Can I export specific collections when exporting data from Firebase to CSV?
Yes, you can export specific collections using the Cloud Firestore managed export and import service.
Does exporting data from Firebase to CSV include subcollections automatically?
Exporting a collection will not automatically export its subcollections.
Is it possible to load Firebase exports into BigQuery?
Yes, you can load Cloud Firestore exports into BigQuery, provided you specified a collection-ids filter.
Do I need to enable billing on my Google Cloud project to use the Firebase export to CSV functionality?
Yes, you must enable billing for your Google Cloud project to use the managed export service.
Conclusion
Exporting data from Firebase to a CSV file involves several steps and considerations, such as incurring a read operation for each document exported and ensuring proper permissions are set for the Cloud Firestore service agent. While the native functionality for direct CSV export is not provided, Firebase's managed export and import services offer robust solutions for data backup, recovery, and offline processing. It is important to enable billing, be aware of the associated costs, and understand that exporting to a CSV will not be reflected in the usage console. However, for a more streamlined and efficient process, consider using Sourcetable, which allows you to import your data directly into a spreadsheet, bypassing the complexities of manual exports.
