Open Mockaroo Why this one
Create sample customers, orders or other rows with the columns your project expects. Useful for testing a dashboard or assistant-written code before connecting real records.
Try this first
Define an order ID, category and amount, generate 100 rows and download a CSV. Check the column types and include a few deliberate blank or unusual values in your test copy.
How it helps your AI
Give an assistant synthetic input for building or debugging an import, chart or dashboard. Keep known edge cases so you can verify the code's behaviour.
