Frequently Asked Questions
How specific should my description be?▼
The more specific, the better. List field names, data types, value ranges, and constraints. For example: 'Products with id (integer), name (string), price (0.99–999.99), category (electronics/clothing/food), and in_stock (boolean)' will generate much more useful data than 'Products'.
Are the values actually realistic?▼
Yes — DeepSeek generates real-sounding names, valid email formats, plausible numbers, proper ISO dates, and diverse values. It avoids placeholder text like 'string1' or '[email protected]'.
What's the maximum number of records?▼
Up to 500 records per generation. For larger datasets, generate in batches and combine the outputs. Very large counts (250+) may take 15–20 seconds due to API output limits.
Can I customise the SQL table name?▼
Yes — the Table Name field appears when you select SQL format. The output includes a CREATE TABLE statement followed by INSERT statements for all rows.
Is this data safe to use in production?▼
Mock data is intended for development and testing only. Never use generated data in production systems, especially for anything involving personal information.
