Firebase vs Firestore

Understanding Firebase database options:

• Realtime Database: JSON tree structure, best for real-time sync (this converter)
• Firestore: Document-based NoSQL, better for complex queries
• Our Converter: Optimized for Firebase Realtime Database JSON format

Firebase REST API Integration

The generated Firebase data can be imported via REST API:

• PUT Request: Upload entire JSON structure to Firebase endpoint
• PATCH Request: Update specific nodes in Firebase database
• POST Request: Add new records with auto-generated keys
• Authentication: Use Firebase auth tokens for secure imports

Privacy & Security

Your data security is our priority. All CSV to Firebase conversions happen entirely in your browser using client-side JavaScript. Your CSV files and Firebase JSON never leave your computer or get uploaded to any server, ensuring complete privacy and security for sensitive application data.

Tips for Perfect Firebase Import

• Use a unique column (like ID) as custom key for better data organization
• Enable type conversion to ensure numbers aren't stored as strings
• Remove special characters from column names before conversion
• Test with small dataset first before importing large CSV files
• Backup your Firebase database before importing new data
• Use Firebase security rules to protect imported data

CSV to Firebase FAQ

Is this CSV to Firebase converter free to use?

Yes. The CSV to Firebase converter is completely free with no usage limits or registration required.

Does my CSV or Firebase JSON get uploaded to your servers?

No. All CSV to Firebase conversions run entirely in your browser using client-side JavaScript, so your data never leaves your device.

Which Firebase product is this JSON compatible with?

The generated JSON structure is designed for Firebase Realtime Database. You can import it directly in the Firebase Console or via the REST API.

Can I use a custom key instead of item_0, item_1, etc.?

Yes. Use a unique column (like an ID field) as your key column when preparing the CSV so that each Firebase child node has a meaningful key.

How are empty cells in my CSV handled?

Empty CSV cells are converted to empty strings by default. You can post-process the JSON if you prefer to use null values instead.

Is there a limit on CSV file size?

The practical limit depends on your browser and device memory. For very large CSV files, consider splitting the data into smaller chunks before converting and importing.

Can I use this converter for production databases?

Yes, but always test with a small dataset first and make sure you have a backup of your Firebase database before importing large or critical data.
