🧠 How to Use

🎬 Overview

Sample Data Generator enables developers to quickly create realistic, localized sample data directly within OutSystems.
It’s ideal for testing APIs, populating dashboards, or mocking list screens — all without connecting to any real data source.

You can use it in two flexible ways:

• 🧩 Visual Builder – Interactive field & type selection.

• </> JSON Editor – Write your own JSON schema for advanced use cases.

⚙️ Step-by-Step Guide

🧩 Option 1: Visual Builder Mode

1. Open the Sample Data Generator app.

2. In the Visual Builder tab:

   • Enter a field name (e.g., Name, Email, City).

   • Select a type (e.g., name.fullName, internet.email, address.city).

   • Set the Row Count (e.g., 100).

3. Click Generate.
   → The right panel will show the generated JSON.

4. Use Copy or Export to Excel to download your data file.

</> Option 2: JSON Editor Mode

For developers who prefer manual control, define your fields directly in JSON format.

Example:

{
  "fields": [
    { "name": "Name", "type": "name.fullName" },
    { "name": "Email", "type": "internet.email" },
    { "name": "City", "type": "address.city" },
    { "name": "Phone", "type": "phone.phoneNumber" }
  ],
  "count": 5
}

Then click Generate to produce the corresponding JSON data.

🌐 Locale Selection

At the top-right, use the Locale Dropdown to control the data’s regional format.
This affects:

• Name order (e.g., “Kim Minjun” vs “Minjun Kim”)

• Country and city names

• Phone number format
