BSON — Binary JSON (MongoDB)
The records as BSON — the binary-JSON encoding MongoDB stores documents in. For testing BSON decoders and JSON↔BSON conversion.

What is a .bson file?
BSON (Binary JSON, .bson) is the binary-encoded serialization MongoDB uses to store documents. It extends JSON with typed values (ObjectId, dates, binary, decimal128) and length-prefixed fields for fast traversal.
How to use this file
Use an example .bson file to test BSON parsers, MongoDB import/export (mongodump/mongorestore), and BSON-to-JSON conversion.
How to use this file for testing
“BSON — Binary JSON (MongoDB)” is a deterministic Novus Examples fixture for Conversion testing, Serialization testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: 5 rows · 7 columns · BSON. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
Data fixtures document their exact quirks — delimiters, encodings, null handling, schema, and row counts — in the spec table. Point your parser or importer at the file and assert it handles the documented edge cases; clean and deliberately-messy siblings make before/after diffs straightforward.
