How to use
- Add fields and pick a type for each (name, email, date, number range, UUID, enum…).
- Set row count, locale and seed.
- Preview and download.
Worked example
Seed 42 with the default fields id (UUID), name, email and signup_date generates the same 500 rows every time; seed 43 gives different rows. Every email uses a reserved example domain such as example.com.
Supported formats and limits
| Output | CSV, JSON, JSON Lines, SQL INSERT, XLSX |
|---|---|
| Limits | Up to 100,000 rows. |
| Engine | Faker with a fixed seed |
Limitations
- Generated names, phone numbers and street addresses are fictional but may coincidentally match real people or places.
- The same seed reproduces the same data with this version of the generator; a future library update may change the values.
Questions
Can I generate the same dataset again?
Yes. The same fields, row count, locale and seed always give the same rows, so seed 42 reproduces the same 500 records. Change the seed, or use the random seed button, for a different set.
Are the generated emails safe to use?
Emails are built from the generated names on the reserved example.com, example.net and example.org domains, which cannot belong to a real mailbox. Names, phones and addresses are fictional but can coincide with real ones.
Which output formats are supported?
CSV, JSON, JSON Lines, XLSX and SQL INSERT statements for ANSI SQL, MySQL or SQL Server, with an optional CREATE TABLE and a batch size.
