Is the generated data safe to use in production?

No — mock data is for development and testing only. All names, emails, phone numbers, and addresses are randomly generated and entirely fictional. Never use fake data in production as it contains no real records.

Does my data get sent to a server?

No. All data is generated entirely in your browser using JavaScript. Nothing is sent to any server, making it safe for internal and privacy-sensitive projects.

Can I choose which fields to generate?

Yes. Use the checkboxes to select exactly which fields you need — from a minimal id + email pair to a full profile with address, company, job title, and more. Only selected fields appear in the output.

What output formats are supported?

The generator outputs JSON (array of objects), CSV (with headers), and SQL INSERT statements ready to paste into a database. Each format can be copied to clipboard or downloaded as a file.

What is the maximum number of rows I can generate?

You can generate up to 100 rows at a time. For larger datasets, click Generate repeatedly and combine the outputs, or use a dedicated library like Faker.js in your codebase.
