Mocksheets is a free AI-powered test data generator that creates structured, schema-aware test datasets with edge cases, boundary values, and realistic distributions — export to CSV, JSON, or Excel.
Generate comprehensive test datasets in seconds. Include null values, max-length strings, special characters, and boundary conditions — all from a plain English description.
Ask Mocksheets to include any of these in your test data:
Include rows with null, empty string, or missing field values to test null handling
Min/max integers, very long strings, dates at epoch boundaries, zero-value amounts
Unicode, emojis, SQL injection patterns (for testing sanitization), HTML entities
Leap years, timezone boundaries, far past/future dates, DST transitions
Negative balances, returns, refunds, and below-zero temperature/elevation values
Include intentional duplicates to test deduplication logic and constraint validation
Test data is realistic data used to validate software functionality during QA testing. A test data generator automates the creation of this data so you don't manually write hundreds of test records. It supports edge cases, boundary values, and realistic distributions needed for thorough testing.
Yes. Describe your database schema in plain English or paste your table structure, and Mocksheets will generate matching test data with proper relationships, data types, and constraints.
Yes. Ask Mocksheets to include edge cases such as null values, very long strings, special characters, min/max boundary values, future/past dates, or negative numbers — and it will incorporate them into the generated dataset.
Yes. Mocksheets exports test data as CSV, Excel (.xlsx), and JSON. The JSON format is useful for API testing, mocking backend responses, and populating test fixtures in unit tests.
Test data is designed to test software behavior, including boundary conditions and error states. Fake data is primarily realistic-looking placeholder data for demos. Mocksheets supports both from the same interface.
