Mock Data Generator
NewBuild a custom schema by selecting field types (name, email, phone, UUID, date, address, city, country, company, number, boolean, URL, color) and generate 1–100 rows of realistic fake data. Export as JSON array or CSV. All generation is 100% client-side using a seeded PRNG — no network requests.

Frequently Asked Questions
Is the generated data truly random?
Data is generated using a seeded pseudorandom number generator (Park-Miller PRNG) seeded from the current timestamp. UUIDs use crypto.randomUUID() for cryptographic randomness. Each Generate click produces a fresh dataset.
Can I use this data in production?
No — this tool generates fictitious data for testing purposes only. Names, emails, and addresses are randomly assembled from example data and are not real people or valid addresses.
