CBOR ⇄ CDN playground with CDDL validation

Convert between CBOR bytes, Concise Diagnostic Notation (CDN / CBOR-EDN), and JavaScript values, with live validation against CDDL schemas. Annotated hex dumps, lossless round-trips, formatting options, and shareable links.

powered by @cbortech/cbor — RFC 8949, RFC 8610 & draft-ietf-cbor-edn-literals

UUID toolkit

Generate UUID v4 and monotonic UUID v7, and inspect any UUID: version, variant, embedded timestamp, and a color-coded field breakdown for versions 1–8.

Float notation & IEEE 754 inspector

Enter a floating-point literal in any CDN notation — decimal, exponential, hex float, an integer base, NaN/Infinity, or a float'...' bit pattern — and see every other spelling plus its half-, single-, and double-precision binary representation — with quadruple precision (binary128) included as reference info.
