Invalid UUID format

UUID copy and paste validation

Why does a UUID copied with quotes fail?

JSON strings, JavaScript literals, SQL output, and logs often display UUID values inside quote characters. Those quotes are serialization syntax, not part of the UUID itself, so VetaTool's bare UUID validator rejects them. This tool is free to use. No account or payment is required.

What you can do here

  • Canonical 8-4-4-4-12 UUID validation
  • UUID version inspection
  • RFC 4122 variant checking
  • Nil UUID recognition
  • Uppercase hexadecimal support
  • Browser-local validation

Steps

  1. Paste the quoted text exactly as copied.
  2. Remove the opening and closing quote characters.
  3. Validate the remaining 8-4-4-4-12 UUID text.

Serialization wrappers are outside UUID syntax

The UUID inspector does not parse JSON or programming-language literals before validation. It checks the provided string after trimming leading and trailing whitespace.

If the underlying UUID is canonical, removing the wrapper quotes is enough to reach version and variant inspection.

Quoted UUID example

The surrounding quotes make the supplied text non-canonical.

Common questions

Frequently asked questions

Are quotes allowed in a UUID value?

No. Quotes can delimit a string in JSON or source code, but they are not characters in the canonical UUID itself.

Does trimming remove quote characters?

No. String trim removes surrounding whitespace, not punctuation such as quotes.
