How to Convert JSON to BSON - Step by Step Guide

Step 1

Input Your JSON Data

Let's convert your JSON to BSON format! Whether you're preparing data for MongoDB imports, working with MongoDB drivers, or optimizing storage, you have several convenient options:

•
Paste directly: Copy your JSON data from applications, APIs, or database exports
•
Upload a file: Click "Upload" to select a .json or .txt file from your computer
•
Try the sample: Click "Sample" to load example JSON and see the BSON conversion

Example: JSON Input

Here's a typical JSON structure ready for BSON conversion:

{
  "customerId": "CUST-12345",
  "phoneNumber": "+1555-1234567",
  "planType": "Unlimited 5G",
  "dataUsageGB": 45,
  "isActive": true
}
Step 2

Choose Output Format

Select how you want your BSON binary data to be encoded for display and transfer:

•
Base64 encoding: More compact format, ideal for APIs and web transmission
•
Hex encoding: Easier to debug byte-by-byte, useful for development
•
Automatic conversion: JSON automatically encodes to BSON with MongoDB-specific type optimization

Example: BSON Output (Base64)

The same JSON, now encoded as BSON in Base64 format:

Step 3

Export Your BSON Data

Get your encoded BSON ready for MongoDB! Multiple export options make integration seamless:

•
Copy to clipboard: One-click copying for quick pasting into MongoDB Compass or application code
•
Download as .bson: Save binary file for direct use with mongorestore and MongoDB imports
•
Ready for MongoDB: Optimized binary format with proper type information for efficient database operations

Frequently Asked Questions

How do I convert JSON to BSON for MongoDB?

Simply paste your JSON data into the converter, choose your preferred output format (Base64 or Hex), and the tool automatically encodes it to BSON. The converter handles all MongoDB-specific data types including ObjectId, Date, and Binary.

What's the difference between Base64 and Hex output?

Both represent the same BSON binary data as text. Base64 is more compact and commonly used for APIs and web transmission. Hex is easier to debug byte-by-byte and useful for development and troubleshooting.

How do I import the BSON into MongoDB?

Download the .bson file and use mongorestore to import it, or copy the encoded BSON and use MongoDB drivers to insert documents programmatically into your database.

Does the converter support MongoDB-specific types?

Yes! The converter automatically handles MongoDB-specific types including ObjectId, Date, Binary, Decimal128, and Timestamp. It recognizes Extended JSON (EJSON) format and converts them properly to BSON.

Can I convert large JSON files to BSON?

Yes! The converter handles large JSON files efficiently. All conversion happens in your browser for maximum privacy, and there are no file size limitations or conversion frequency restrictions.

Is this JSON to BSON converter free?

Yes, completely free with unlimited conversions. No registration required, and you can convert as much JSON to BSON as needed. All processing happens locally in your browser for security and privacy.
