How many records can I generate?

You can generate up to 1,000 records at a time. All generation happens in your browser - no data is sent to a server.

What is the Enum type?

Enum lets you define a custom list of allowed values, comma-separated (e.g. active,inactive,pending). Each record will randomly pick one value from your list. Great for status fields, categories, and roles.

Can I use this for database seeding?

Yes - select 'SQL INSERT' format, enter your table name, and the tool generates a CREATE TABLE statement plus INSERT statements for all records. Copy directly into your SQL client or migration file.

Is the generated data realistic?

Yes - names, emails, addresses, companies, and job titles are drawn from curated real-world pools. Email addresses are formatted as firstname.lastname@domain.com. Phone numbers follow the +1XXXXXXXXXX format.
