Firestore Importer

Automatically import JSON and CSV files from Cloud Storage into Firestore collections.

This extension allows you to easily import data from JSON and CSV files into Firestore. Simply upload your files to a designated folder in your Cloud Storage bucket, and the extension will automatically process them and import the data into your specified Firestore collection.

How it works

1. You upload JSON or CSV files to a specified folder in your default Cloud Storage bucket.
2. The extension detects the new file and processes it based on its format:
   • JSON files: The extension parses the JSON and imports it into Firestore.
   • CSV files: The extension converts the CSV to JSON (using the first row as field names) and imports it into Firestore.
3. The data is written to your specified Firestore collection using efficient batch operations.

Use cases

• Bulk import user data
• Import product catalogs
• Load test data for development and testing
• Periodically update Firestore collections from external data sources

Best practices

• For large datasets, consider splitting your data into multiple smaller files to improve processing efficiency.

• For JSON files, structure your data in a way that matches how you want it stored in Firestore.
