What is BSON ↔ JSON Converter / Viewer?

This tool converts JSON to BSON and decodes BSON back to JSON.

It is useful for MongoDB-related debugging, binary payload inspection, backend development, and interoperability testing.

How to use BSON ↔ JSON Converter / Viewer

  1. Paste JSON and click Encode to convert it into BSON.
  2. Paste Base64 or hex BSON and click Decode to convert it into JSON.
  3. Use Auto-detect if you are not sure whether the input is JSON, Base64, or hex.
  4. Upload or download .bson files when needed.

Tips

  • BSON is a binary format, so Base64 and hex are the most convenient text representations.
  • This tool is especially useful when debugging MongoDB exports or binary payloads.
  • Hex output helps compare BSON payloads byte by byte.
  • BSON expects a top-level document, so encoding works best with JSON objects.
