BSON & MongoDB Extended JSON Guide

What is BSON?

BSON (Binary JSON) is a binary-encoded serialization of JSON-like documents. MongoDB uses BSON as its primary data storage and network transfer format. BSON supports additional data types not available in standard JSON.

Extended JSON Format

MongoDB Extended JSON is a string format for representing BSON documents. It allows you to work with BSON types in a human-readable JSON format:

ObjectId: {"$oid": "507f1f77bcf86cd799439011"}
Date: {"$date": "2024-01-01T00:00:00Z"}
Long: {"$numberLong": "9223372036854775807"}
Binary: {"$binary": {"base64": "...", "subType": "00"}}

ObjectId Structure

A MongoDB ObjectId is a 12-byte identifier consisting of:

TTTTTTTTMMMMMMPPPPCCCCCC
T (8 chars): Unix timestamp
M (6 chars): Machine identifier
P (4 chars): Process ID
C (6 chars): Counter
