Generate realistic, locale-aware fake data for US and UK testing workflows. Powered by Faker.js.
Every development team needs test data — for populating databases, stress-testing APIs, building demos, and validating data pipelines. devmeldex's free fake data generator uses Faker.js to produce realistic, locale-aware mock data for US and UK contexts. Names, addresses, postcodes, phone numbers, and company names all follow the conventions of the selected locale. Generate up to 500 rows of test data in JSON, CSV, or plain text — all processed entirely in your browser with zero data sent to any server.
Need 10 rows of UK customer data with name, email, and postcode
[ {"Full Name": "Olivia Thompson", "Email": "[email protected]", "Postcode": "SW1A 2AA"}, ... ]
Selecting the UK locale generates properly formatted British names, .co.uk emails, and valid-format postcodes.
Choose between English (US) or English (UK) to generate data in the correct format for your region.
Select from 19 field types across Person, Business, Address, Tech, Finance, Date, and Text categories.
Use the slider to choose between 1 and 500 rows of generated data.
Select JSON, CSV, or Plain Text depending on how you will use the data.
Click Generate to create your dataset, then Copy to clipboard for immediate use.
Populate development and staging databases with realistic test records without using production data.
Generate thousands of realistic payloads for stress-testing REST and GraphQL endpoints.
Fill mockups and prototypes with realistic data that looks natural to stakeholders.
Replace production personal data with synthetic alternatives in non-production environments, eliminating data protection risk.
