Data Creator

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.
