Free Synthetic Data Generator

Create Dummy, Fake & Mock Data Instantly From a Prompt

In today’s data-driven world, developers, educators, and analysts constantly need realistic data to test software, create dashboards, or run classroom exercises. But using real customer or patient data is often off-limits due to privacy concerns, regulations, or simple availability. That’s where synthetic data steps in.

Our free online tool allows you to instantly generate dummy data, fake data, and mock data on demand, tailored to your needs. By entering a simple prompt like “create 500 rows of retail transaction data with realistic item categories and prices”, you’ll receive a full dataset you can download and visualize. The data looks and behaves like the real thing—without ever exposing sensitive information.

How It Works

  1. Enter a prompt: Describe the dataset you need (e.g., “generate 500 fake invoices with realistic dates, clients, and amounts”).
  2. Customize parameters: Choose schema, row counts, value ranges.
  3. Generate instantly: Our AI engine creates dummy data aligned with your prompt.
  4. Export in multiple formats: CSV, JSON, SQL, or Excel.

Within seconds, you’ll have a dataset ready to drop into your project.

Key Features of Our Free Data Generator

✔️ Privacy-Safe Data Generation (No PII)

Unlike “anonymized” datasets that may still carry traces of real people’s information, synthetic data is created entirely from scratch. This ensures zero risk of exposing sensitive customer records, healthcare details, or financial transactions. You can safely use it in demos, client presentations, and open-source projects.

🎯 Focus on Niche Domain Scenarios

Not all data needs are generic. Sometimes you need highly domain-specific datasets: medical patient records for testing an EMR dashboard, accounting ledgers for a student project, or transaction logs for fraud detection models. Our tool allows you to specify the niche context in your prompt, and it generates datasets that fit those needs.

💡 AI-Powered On-Demand Data Sampling

At the core of our tool is a generative AI engine that simulates realistic distributions of values. This means your fake data isn’t just random—it follows patterns consistent with the real world. You can request datasets on the fly (“generate 1000 e-commerce orders with realistic SKUs and timestamps”) and receive structured results instantly.

Benefits Over Manual Methods

Traditional “dummy data” generators produce repetitive, unrealistic values that don’t reflect real-world variation. Our AI-driven tool goes further:

  • Generates statistically consistent datasets that mirror actual patterns.
  • Ensures data diversity (no identical repeated rows).
  • Allows on-demand customization for niche scenarios, from healthcare to education.

This makes the synthetic data not just filler, but actually useful for prototyping, training, and visualization.
