How to Convert BSON to JSON

Step 1

Input BSON Data

Paste your BSON data in Base64 or Hex format, or upload a .bson file exported from MongoDB. The converter supports all BSON data types including ObjectId and Date.

Step 2

Automatic Decoding

The converter automatically decodes BSON binary format to readable JSON, preserving all MongoDB-specific data types and structure.

Step 3

Download or Copy JSON

Get your decoded JSON data ready for use in applications, debugging, data analysis, or migration to other databases.

What is BSON?

BSON (Binary JSON) is a binary-encoded serialization format used by MongoDB. It extends JSON's data model to provide additional data types like Date, ObjectId, and Binary, making it more efficient for database operations.

While BSON is designed for internal MongoDB operations, converting to JSON is essential for debugging, API integration, or when migrating data to other systems. BSON is faster to parse than JSON but not human-readable in its binary form.

Frequently Asked Questions

What is BSON used for?

BSON is MongoDB's native storage format. It's used for storing documents, transmitting data between MongoDB drivers and servers, and in MongoDB's binary dumps.

How do I get BSON data from MongoDB?

Use mongodump to export BSON files, or use MongoDB drivers to serialize documents to BSON format.

Is BSON faster than JSON?

Yes, BSON is faster to parse and traverse because it includes length prefixes and type information. However, it may be slightly larger in size than JSON.

What happens to MongoDB ObjectIds?

ObjectIds are converted to their 24-character hexadecimal string representation in JSON, preserving their uniqueness while making them readable.

Is this converter free?

Yes, completely free with unlimited conversions. All conversion happens in your browser for maximum privacy.
