BSON to JSON Converter
Convert Binary JSON (BSON) to readable JSON format. Decode MongoDB's BSON data exports into standard JSON with automatic type conversion. Perfect for database debugging, data migration, and API integration.
Recommended Settings
Input Format
- •Use hexadecimal for bsondump output
- •Use Base64 for encoded binary transfers
- •Remove whitespace for cleaner input
MongoDB Types
- •ObjectIds convert to hex strings
- •Dates convert to ISO 8601 strings
- •Binary data converts to Base64
Pro Tips
- •Select the correct input format (hex or base64)
- •BSON data from MongoDB's bsondump is in hex format
- •All conversion happens client-side for privacy

Frequently Asked Questions
What is BSON?
BSON (Binary JSON) is a binary-encoded serialization format used primarily by MongoDB. It extends JSON with additional data types like Date, Binary, ObjectId, and Decimal128, making it more efficient for storage and data traversal.
What format should my input be?
Since BSON is binary data, you need to provide it as either a hexadecimal string or Base64-encoded string. You can select your preferred input format using the format selector. MongoDB's bsondump tool outputs hex format by default.
How are MongoDB-specific types handled?
MongoDB types like ObjectId, Date, and Binary are converted to their JSON-friendly representations. ObjectIds become hex strings, Dates become ISO strings, and Binary data becomes Base64. The conversion preserves all data while making it readable.
Is my data safe?
Absolutely! All conversion happens entirely in your browser using client-side JavaScript. No data is ever sent to any server, ensuring complete privacy and security for your MongoDB data.
Can I convert large BSON files?
Yes, but very large files may take longer to process since conversion happens in the browser. For optimal performance, files under 10MB are recommended. For larger files, consider breaking them into smaller chunks.
