locale: en-SEYAML output is 9% smaller than the Protobuf input. The same data is 140 characters as minified JSON and 218 as pretty-printed JSON. Sizes are character counts, not tokens: token counts depend on the model's tokenizer (see the tokenizer comparison).
Protobuf to YAML: what changes
- Reading Protobuf: Input is Protobuf text format (the readable form used in .textproto files and debug output), not the binary wire format. Repeated fields are collected into arrays; no .proto schema is read, so types are inferred from the values.
- Writing YAML: Strings that would otherwise change type on re-read, such as '2021' or '1.0', are quoted. No comments are generated.
About Protobuf
Protocol Buffers is a binary serialization format from Google. Extremely compact and fast, but requires a schema definition.
- ✓Very compact
- ✓Fast serialization
- ✓Schema evolution
- ✓Type-safe
About YAML
YAML is a human-friendly data serialization format. It uses indentation instead of brackets, making configuration files more readable.
- ✓Human readable
- ✓No punctuation
- ✓Supports comments
- ✓Great for config
Why Convert Protobuf to YAML?
Use YAML for configuration files, especially in DevOps (Docker, Kubernetes, GitHub Actions). It's more readable than JSON but can have ambiguity with indentation.
