Mockaroo

Mockaroo is an online random data generator. A schema is defined field by field, choosing a type and options for each column (names, e-mail addresses, IP addresses and many others), and Mockaroo generates realistic test data in CSV, JSON, SQL or Excel format. Fields can also be generated with AI or derived from an example.

Beyond datasets, Mockaroo can mock back-end APIs so that front-end development can start before the back end exists, and it offers projects, scenarios, functions, database generation and de-identification features.

Up to 1,000 rows can be generated for free; paid plans raise the limits, and Mockaroo is also available as a Docker image for deployment in a private cloud.
