Can I generate test data from a CREATE TABLE statement?

Yes. Paste the definition into the Schema Data Generator, adjust ranges if needed and generate up to 500,000 rows.

Is generated test data safe to share?

The values are made up, so it contains no real people. For real files, use Data Masking and check the result before sharing.

Test Data Tools for QA Engineers

Generate test data from a schema or sample file, mask production data, build JSON fixtures and compare outputs before and after a change. Free, in your browser.

The problem

QA engineers need test data that is realistic, safe to share and easy to reload. Copying production data brings privacy risk, and writing data by hand is slow.

Typical jobs and the tool for each

Generate by schema: Schema Data Generator takes a CREATE TABLE or table definition and creates up to 500,000 rows. The Data Generator offers ready datasets (users, orders, products, employees, transactions, sensor readings, students) in CSV, Excel, JSON or Parquet.

Look like production without being production: Synthetic Data Generator learns the statistics of a sample file and creates new rows, and Data Masking hides personal data in an existing file.

Fixtures: generate JSON and validate it with the JSON Formatter, which shows the exact line of any error.

Regression checks: Data Comparison lists the rows and cells that changed between two CSV or Excel exports.

Limits to know

Generated values are made up and follow ranges and formats, not your business rules, so check that they satisfy the constraints your system enforces. Data Comparison reads CSV and Excel only. Masking finds common patterns, so review the column list yourself.
