Mockium
Mockium generates fake data from user-defined fields and schemas and can export results in formats such as CSV, SQL, JSON, and XML.
About Mockium
Mockium is a web-based test data generator. Users define fields by name, data type and type-specific settings, arrange field order, then generate output in CSV, SQL, JSON and XML. Output options include row and file counts, filenames, CSV delimiters, quotes, line endings and headers, XML tags, and SQL table names with create-table statements.
Schemas can be saved locally in the browser, cloned for reuse, exported to a file, and imported later on another computer.
