Mock and Match is a free, 100% client-side toolkit for developers: generate realistic fake test data (CPF, CNPJ, UUIDs, emails, credit cards and 50+ field types) with a visual schema builder, export to JSON/CSV/SQL, and convert between JSON, YAML, XML, TypeScript, Zod, JSON Schema and TOON — plus a JSON formatter/minifier. No signup, no data ever leaves your browser.
