JSON To Go BSON Converter

Convert JSON into Go BSON literals

Go applications that use the official MongoDB driver often build documents with bson.M maps and bson.A arrays instead of typed structs. When you already have JSON fixtures, migration samples, or API payloads, rewriting them by hand into BSON literals is repetitive. This tool transforms JSON into Go code you can paste into tests, seed scripts, or quick prototypes.

What this tool does

Paste JSON in the input panel. The converter parses the payload, formats it, and rewrites object braces into bson.M{...} and array brackets into bson.A{...}. The output is a Go-friendly literal block you can drop into functions that expect BSON document values.

When to use BSON literals

• Seed MongoDB collections from JSON fixtures in Go integration tests.
• Prototype update and insert operations before defining struct models.
• Convert API response samples into driver-ready document maps.
• Share readable BSON examples in code reviews and documentation.

For strongly typed Go structs instead of BSON literals, use the JSON to Go POJO Generator. You can also format JSON with the JSON Formatter or convert payloads to YAML with the JSON to YAML Converter.
