Quick Start

bash

# Generate 10 fake users as JSON
python3 scripts/mock_data.py user --count 10

# Generate fake email addresses
python3 scripts/mock_data.py email --count 5

# Generate addresses
python3 scripts/mock_data.py address --count 3

# Generate a custom record with multiple fields
python3 scripts/mock_data.py record --fields "name,email,phone,company" --count 5

# Output as CSV
python3 scripts/mock_data.py user --count 20 --format csv

# Output as SQL INSERT
python3 scripts/mock_data.py user --count 10 --format sql --table users

# Single values (no count)
python3 scripts/mock_data.py uuid
python3 scripts/mock_data.py name
python3 scripts/mock_data.py lorem --words 50

# Save to file
python3 scripts/mock_data.py user --count 100 --format csv --output test_users.csv
