Validators
Validators to check whether a value is in the correct format: CPF, CNPJ, email, JSON, URL and UUID. The check runs in your browser and verifies the structure and, for CPF and CNPJ, the check digits — it does not query external databases to confirm that the value actually exists. Pick a validator below and paste the value.
