BSON Viewer

BSON Viewer provides a focused capability for examining BSON binary documents without altering the source data. It accepts inputs as hex, base64, or raw BSON and returns a readable JSON-like representation that preserves BSON types. This enables quick validation of field types, nested structures, and binary payloads in debugging sessions.
Conceptually, the tool maps BSON types to equivalent JSON representations, ensuring fidelity for integers, long values, binary data, and nested documents. Rendering is non-destructive, allowing safe exploration of payloads from MongoDB collections, message queues, or binary APIs. It also supports a basic structural validation view to flag common schema patterns and type mismatches.
Core features include a robust parser, hierarchical rendering, and options for pretty-printed JSON or extended JSON. Advanced users can export results, switch to extended JSON formatting, and generate lightweight validation notes. The tool distinguishes itself by in-browser parsing that respects user privacy, precise type handling, and compatibility with common BSON variants used in MongoDB ecosystems.
Use cases include database debugging, API integration testing, data migration checks, and learning BSON concepts. The combination of accurate parsing, clear output, and export options reduces debugging time and improves data quality for engineering teams.
