What is BSON?
BSON (Binary JSON) is a binary-encoded data format created by MongoDB to store and exchange documents efficiently. Unlike plain JSON, BSON supports native data types like ObjectId, Date, Binary, and Decimal128, enabling MongoDB to index, sort, and query data with precision while maintaining fast read/write performance. While BSON is optimized for database operations, using a BSON to JSON converter makes the data human-readable and compatible with standard tools.
- MongoDB stores every document as BSON so it can preserve data types beyond plain JSON.
- Common BSON-only types include ObjectId, Date, Binary, Decimal128, and timestamps.
- When you export or capture BSON from MongoDB, converting to JSON makes it readable and portable.
BSON vs JSON: Key Differences
| Feature | JSON | BSON |
|---|---|---|
| Encoding | Text-based (UTF-8) | Binary-encoded |
| Data Types | String, Number, Boolean, Null, Array, Object | All JSON types + Date, Binary, ObjectId, Decimal128, Int32/Int64 |
| File Size | Larger (text requires more bytes) | Smaller (binary compression) |
| Human Readable | Yes | No (requires decoding) |
| Use Cases | APIs, web data exchange, config files | Database storage (MongoDB), data replication |
| Parsing Speed | Slower (text parsing) | Faster (binary + traversable structure) |
💡 When to Use This Tool: Whenever you export MongoDB data via mongoexport or mongodump, or capture binary payloads from MongoDB drivers, converting to JSON makes the data readable for debugging, API integration, or data migration.

BSON to JSON FAQs
Get answers to common questions about converting BSON to JSON
BSON (Binary JSON) is a binary-encoded serialization format used to store and transmit data. It's the primary data format used by MongoDB and supports more data types than standard JSON, including Date, Binary, ObjectId, and others.
Base64 is a text encoding method that uses 64 different ASCII characters to represent binary data, making it ideal for network transmission. Hex (hexadecimal) uses 16 characters (0-9, A-F) to represent binary data and is often used for debugging and low-level data inspection.
Converting BSON to JSON makes your data human-readable and compatible with standard JSON tools and APIs. While BSON is more efficient for storage and transmission, JSON is universal and easier to work with in most programming environments.
Yes. All BSON to JSON conversion runs locally in your browser with no uploads, so your MongoDB data stays private on your device.
Yes. BSON-specific types like ObjectId, Date, and Binary are preserved in the JSON output so MongoDB data stays readable and accurate.
