GoMask

Meet GoMask

GoMask generates sample datasets from a plain-language description. Users can specify the relationships they want to model, such as different churn rates between customer groups, values that vary together, or a chosen amount of missing data. A small free preview lets them inspect the result and adjust the request before generating a larger file.

The service supports linked tables, sourced reference values, and several export formats, including CSV, Excel, JSON, Parquet, and SQL. Data can also be accessed through an API. GoMask is useful for testing an application, preparing an analytics demonstration, or practicing a data workflow when production records are unavailable or inappropriate to use.
