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.

Examples

  • Path 
    $.users[0].name

About JSONPath Tester

Digging one deeply nested field out of a large JSON response by eye is slow and error-prone, especially inside arrays of objects.

Write a JSONPath-style expression - `$`, dot notation, `[index]`, and `[*]` wildcards are all supported - against your document and see the extracted value immediately, which is a lot faster than writing throwaway code just to check a path.
