Data Creator 4+

Generate realistic data in seconds. Perfect for developers and testers who need smart, custom datasets for demos, prototyping, and stress testing. Optimized for macOS 15.

Smart, fast, and realistic data generation for developers, testers, and power users.
Data Creator is a powerful macOS app that lets you generate large volumes of custom, realistic data in just a few clicks. Whether you're a developer, QA engineer, or designer, it's the perfect tool for prototyping, stress-testing, and showcasing apps and websites using meaningful, heterogeneous data.

With a rich internal database of over 50 field types — including names, countries, dates, addresses, email formats, and more — you can build datasets that look real and varied. Define your own structure with flexible fields, custom prefixes/suffixes, date ranges, and number ranges. Then export your records to CSV, TSV, HTML, or any custom format.

Highlights:
• Generate thousands of records in seconds
• Choose from 50+ data types: names, animals, colors, fruits, emails, and more
• Use realistic locale-aware names (e.g., US, German, French, Italian)
• Add custom columns at any time
• Apply formatting: prefixes, suffixes, decimal settings, and custom date ranges
• Manage records like a mini-database (add, delete, sort, undo, refresh)
• Save reusable document templates with full data structure
• Export in CSV, TSV, HTML, or user-defined custom formats
• Clean and intuitive native macOS interface
• Supports tabs, autosave, full-screen, merge, undo, and the latest macOS features

Perfect for:
• Generating demo or placeholder data for apps and websites
• Stress-testing data structures with tens of thousands of records
• Creating realistic datasets for QA and UI/UX testing
• Producing sample data for spreadsheets, reports, or dashboards
• Demonstrating app behavior with believable sample content

How it works:
Choose your columns — from common data types to unique or randomized fields
Set options like quantity, formatting, and field-specific rules
Generate and preview your dataset
Export to your desired format — or save for future editing

Data Creator streamlines your data generation workflow with power, flexibility, and simplicity. Whether you're building a database mockup, testing performance, or just need smart-looking data, it’s your go-to tool.
