Sample Data Generator allows developers to quickly create realistic sample datasets for testing and prototyping within OutSystems applications.

It provides two modes:

• Visual Builder — Select fields and data types interactively.

• JSON Editor — Define custom JSON schema for advanced control.

Supports localization via locale selector, enabling name, address, and phone number formats per region.

Output can be previewed as JSON or downloaded as Excel using the integrated ConvertJsonToExcel action powered by the ClosedXML library.

Ideal for:

• Testing API integrations

• Mocking UI lists and dashboards

• Rapid prototyping with fake but realistic data

Built using Bogus, ClosedXML, and OutSystems Extension (C#) integration.
