CSV Random Row Generator
Stop hand-crafting test data. Define your columns and data types, choose how many rows you need, and generate a realistic fake CSV dataset in seconds — perfect for development, QA, and load testing.
CSV Random Row Generator
Generate synthetic CSV data with configurable column types including names, emails, dates, UUIDs, numbers, booleans, and custom lists
Drop a CSV file to use its headers, or configure columns manually below
Available column types:
- Name: Random first and last names
- Email: Random email addresses with configurable domain
- Date: Random dates within a specified range
- UUID: Universally unique identifiers (v4)
- Number: Random numbers within min/max range with configurable decimals
- Boolean: True/false with configurable probability
- Custom List: Random selection from comma-separated values
What This Tool Does
This tool generates fake but realistic CSV data for testing and development. Define your columns with different data types, specify how many rows you need, and get a CSV file with synthetic data. Perfect for populating test databases, testing imports, or creating sample datasets.
Column Types
Name: Generates realistic first and last names (e.g., "Alice Johnson", "Bob Smith").
Email: Creates valid email addresses (e.g., "[email protected]"). Configurable domain.
Date: Random dates within a specified range. Configurable format (YYYY-MM-DD, MM/DD/YYYY, etc.).
Number: Random integers or decimals within min/max range. Configurable decimal places.
Boolean: Random true/false values. Configurable probability (e.g., 70% true, 30% false).
UUID: Generates unique UUIDs (e.g., "550e8400-e29b-41d4-a716-446655440000").
Custom list: Random selection from your own list of values (e.g., ["Active", "Inactive", "Pending"]).
Example Generated Data
Configuration:
Columns: - id: UUID - name: Name - email: Email (domain: example.com) - signup_date: Date (2023-01-01 to 2024-12-31) - age: Number (18-65) - active: Boolean (80% true) - status: Custom ["Active", "Inactive", "Pending"] Rows: 5
Generated CSV:
id,name,email,signup_date,age,active,status a1b2c3d4-...,Alice Johnson,[email protected],2023-05-15,34,true,Active e5f6g7h8-...,Bob Smith,[email protected],2024-02-28,28,true,Inactive i9j0k1l2-...,Carol White,[email protected],2023-11-03,45,false,Pending m3n4o5p6-...,David Brown,[email protected],2024-06-20,52,true,Active q7r8s9t0-...,Eve Davis,[email protected],2023-08-12,23,true,Active
When to Use This
Database seeding: Populate development and test databases with realistic data.
API testing: Create test payloads for API development and testing.
Performance testing: Generate large datasets to test system performance under load.
Demo environments: Create sample data for product demos and screenshots.
Import testing: Test CSV import functionality without using real customer data.
Privacy compliance: Use fake data instead of production data for development (GDPR, HIPAA compliance).
Configuration Options
Row count: Generate 1 to 10,000 rows. Larger counts for performance testing.
Seed value: Set a seed for reproducible random data. Same seed = same generated data.
Email domain: Specify the domain for generated emails (e.g., "test.com", "example.org").
Date range: Set start and end dates for random date generation.
Number range: Configure min, max, and decimal places for numeric columns.
Boolean probability: Set the percentage of true vs false values.
Reproducible Data
Use the seed option for reproducible random data:
Seed: 12345 → Same 100 rows every time Seed: 67890 → Different but consistent 100 rows
Useful for tests that need consistent data across runs.
Limitations
Not cryptographically secure: Generated data is random but not suitable for security purposes.
Limited name variety: Name generation uses a predefined list. May not represent all cultures.
Maximum rows: Limited to 10,000 rows per generation. For larger datasets, generate in batches.
Frequently Asked Questions
Is the generated data realistic?
Names, emails, and dates look realistic but are completely fake. No real people or companies are represented.
Can I export to formats other than CSV?
This tool generates CSV only. Convert to JSON, SQL, or other formats using other tools in this suite.
How do I generate more than 10,000 rows?
Generate multiple batches with different seeds and merge them using CSV File Merger.
