Fake Data Generator
✓ Link copiedGenerate believable placeholder data for testing, demos, prototypes, and database seeding, entirely in your browser. Choose exactly which fields you need — IDs, first and last names, full names, emails, usernames, phone numbers, street addresses, cities, states, ZIP codes, countries, companies, and job titles — then generate anywhere from a single row to a thousand at once. Each row is internally consistent, so a person's email and username are derived from their name. Preview the result as pretty-printed JSON or RFC 4180 CSV, copy it with one click, or download it as a file. Values are produced from cryptographically strong randomness via the Web Crypto API. Free, fast, and completely private — every row is generated on your device and never sent anywhere.
How to use
Pick the fields you want by toggling them on, set how many rows to generate, and choose JSON or CSV output. Click Generate for a fresh dataset, then use Copy all to put it on your clipboard or Download to save it as a file. Click Generate again any time for a new batch.
Frequently asked questions
- Is the generated data real?
- No. Every value is randomly assembled from generic sample word lists and is not based on any real person, address, or company. It's intended purely as placeholder test data for development, demos, and seeding.
- Can I export it as CSV for a spreadsheet or database?
- Yes. Switch the format to CSV to get RFC 4180 output with a header row and properly escaped values, ready to import into Excel, Google Sheets, or a database. JSON is also available for APIs and code.
- Is my data sent anywhere?
- No. All data is generated locally in your browser using the Web Crypto secure random number generator. Nothing is uploaded, logged, or stored on any server, and no account is required.
