What is TymBits?

TymBits is a collection of free, in-browser developer utilities for working with common data-serialisation formats — Protocol Buffers, Apache Avro, JSON, YAML, and Java .properties — plus generators for sortable XID and URL-safe NanoID identifiers.

The converters run entirely in your browser. Nothing is uploaded, logged, or stored. Paste a payload you received from a backend system and read it as JSON in one click.
