Mock Data Generator

Create realistic mock data by type or from a schema using AI.

Mock data is realistic but fabricated information used for testing, prototyping, and development. Instead of manually creating sample records, this generator produces structured datasets in seconds so you can populate databases, test forms, and validate APIs without waiting for real data.

What is Mock Data?

Mock data simulates real-world information such as names, emails, addresses, dates, and numbers. It is essential during software development because it lets you build and test features before your application has a live user base. Well-structured mock data also reveals edge cases that empty or placeholder values would miss.

This tool supports two generation modes: define a schema by picking data categories and types from the Faker.js library, or describe what you need in plain English and let the AI build the dataset for you. Both approaches output JSON, CSV, or XML.

How to Generate Mock Data

In the Schema tab, add fields and assign each one a category (e.g., person, internet, location) and a data type (e.g., firstName, email, city). Reorder or remove fields with the arrow and trash icons, then set the number of records and click Generate Data.

In the AI Prompt tab, describe the dataset you need in a sentence or two (e.g., “realistic e-commerce product listings”) and specify how many records to create. The AI handles field selection and population automatically. Copy or download the result when generation is complete.

Frequently Asked Questions

What is a mock data generator?

A mock data generator creates realistic fake data — names, emails, addresses, numbers, dates, and more — for testing applications, filling databases, or prototyping.

How do I generate mock data?

Choose from predefined data types (names, emails, addresses, etc.), specify the number of records, and click "Generate." The tool outputs structured JSON, CSV, or plain text.

Can I use AI to generate custom schemas?

Yes. Describe the data structure you need in plain English (e.g., "user records with name, age, and subscription tier"), and the AI generates matching mock data.

What output formats are supported?

Generated data can be output as JSON, CSV, or plain text, making it easy to import into databases, spreadsheets, or API testing tools.
