• Social/Content (7 templates) - User profiles, posts, comments, engagement metrics, media
• Financial (5 templates) - Transactions, accounts, payments, ledgers, invoices
• Healthcare (5 templates) - Patient records, encounters, prescriptions, lab results
• Testing (3 templates) - JMeter JTL files, API access logs, IoT telemetry
• HR (4 templates) - Employee records, performance reviews, timesheets, payroll
• Logistics (3 templates) - Shipments, warehouses, suppliers
• Education (5 templates) - Students, courses, enrollments, grades, assessments
• Marketing (3 templates) - Campaign data, ad impressions, web analytics
• Telecom (3 templates) - Call records, subscriber data, network metrics

The template library continues to expand based on user feedback and industry needs.

Multiple Output Formats

Export your generated data in the format that fits your workflow:

• JSONL - Line-delimited JSON for streaming processing
• CSV - Universal format for spreadsheets and databases
• Parquet - Columnar format for big data tools and analytics

Streaming Generation

Generate massive datasets without memory issues. The platform uses streaming to handle 10M+ row datasets efficiently, delivering data progressively as it’s generated.

Multi-locale Support

Test internationalization with realistic data in 8 locales:

• English (US, UK)
• German
• French
• Spanish
• Japanese
• Italian
• Portuguese

Names, addresses, phone numbers, and dates follow locale-specific formats.

Schema Builder

Need custom data structures? Use the visual Schema Builder to define your own fields, types, and constraints. Build exactly the data schema you need without writing code.

Realistic Distributions

Go beyond random data with statistically realistic distributions:

• Zipfian - For product popularity, word frequency
• Power-law - For network effects, user behavior
• Normal - For measurements, ratings
• Exponential - For time intervals, response times

Web-based Platform

No installation, no dependencies, no Python environment setup. Access the platform from any browser, generate data on-demand, and download results instantly.

Pricing

Annual plans save 17% compared to monthly billing. All tiers include access to the full template library and multi-locale support.

Frequently Asked Questions

What’s included in the free tier?

The free tier provides access to all 50+ templates with pre-generated datasets ranging from 1K-10K rows. You can download up to 10 datasets per day in JSONL, CSV, or Parquet format. No credit card required for signup.

Can I create custom data schemas?

Yes! Basic and Pro tiers include access to the Schema Builder. Define custom data schemas with specific field types, constraints, and relationships using the visual interface. Choose from dozens of field types (strings, integers, emails, dates, etc.) and build exactly the data structure you need.

What formats are supported?

All tiers support three output formats:

• JSONL (JSON Lines) - One JSON object per line, ideal for streaming
• CSV - Standard comma-separated values for spreadsheets and databases
• Parquet - Columnar format optimized for analytics and big data tools

Is there a CLI tool?

Currently, DummyDataGenPro is web-based only. The platform focuses on providing an accessible browser-based interface for immediate data generation without installation requirements.

How does multi-locale support work?

Select your desired locale when generating data, and DummyDataGenPro uses locale-specific generators for:

• Names - Realistic given names and surnames for the locale
• Addresses - Correct street, city, postal code formats
• Phone numbers - Valid number formats with country codes
• Dates - Locale-appropriate date formatting

All 8 supported locales (US, UK, German, French, Spanish, Japanese, Italian, Portuguese) are available across all tiers.

How is this different from Faker or other libraries?

DummyDataGenPro focuses on domain-specific templates rather than generic data generation. Instead of manually composing schemas, choose from 50+ pre-built templates designed for real-world testing scenarios. The web-based platform eliminates installation and environment setup, making it accessible to non-developers.

Additionally, streaming generation handles 10M+ rows efficiently without memory constraints, the Schema Builder provides a visual interface for custom schemas, and the specialized JMeter generator creates realistic test result files.

Can I generate data for compliance testing (GDPR, HIPAA)?

Absolutely. Since all generated data is completely synthetic, there are no compliance concerns. Healthcare templates generate fake patient records, financial templates create synthetic transactions - all safe for testing without exposing real PII or PHI.

This makes DummyDataGenPro ideal for testing privacy features, data anonymization pipelines, and compliance workflows without regulatory risk.
