Click Convert when ready

Override only when Auto cannot parse your paste. Changing this loads a matching sample into Input — click Convert to run. Use Load sample to cycle every format example.

All conversions

Read-only representations of the same 16 bytes. Every textual form is listed here, not in “Prefer format”.

Paste two values: if both sides are valid JSON, a structural diff appears; otherwise UUID / bytes are compared when both decode to the same format.

A
B

Create or edit JSON here (syntax colors), then format, validate, or convert - same as MongoDB $binary UUID blobs on the Convert tab once detected.

New document

Hash, HMAC, AES-GCM/CBC + RSA-OAEP, codecs, JWT decoding, UUID v4, and secure random - all client-side. JWTs use Base64URL (three segments), not a single MIME Base64 block - use Decode JWT below, not raw Base64 decode.

About OpenAPI Viewer

A raw OpenAPI or Swagger spec file is dense - hundreds of lines of YAML or JSON before you can answer a simple question like 'how many endpoints does this API actually have?'

Paste a spec and get an instant summary: title, version, path count, and the HTTP methods in use, parsed entirely client-side. Useful for a first-pass sanity check before diving into the full document or generating client code from it.
