Question 1

What is a test data generator?

Accepted Answer

A test data generator is a tool that creates realistic fake data for testing. It helps developers and QA teams avoid using real personal data while producing structured datasets in formats like JSON and CSV.

Question 2

How do I generate JSON test data?

Accepted Answer

Choose a template (User/Product/Order), set 1–100 records, select JSON, then generate. The tool outputs a JSON array formatted with 2-space indentation so it’s easy to read and reuse as fixtures.

Question 3

Can I import the CSV into a database?

Accepted Answer

Yes. The CSV output includes a header row and escapes special characters (quotes, commas). You can import it into MySQL, PostgreSQL, SQLite, or open it directly in Excel and Google Sheets.

Question 4

Is it free? Do I need to sign up?

Accepted Answer

It’s free to use and requires no signup. Data is generated locally in your browser, so your inputs and outputs stay private.

Question 5

How many records can I generate at once?

Accepted Answer

You can generate 1–100 records per run. This limit keeps the page fast and responsive. If you need more, generate multiple batches and merge them.

Question 6

How realistic is the generated data?

Accepted Answer

The generated data is realistic-looking but entirely fictional. It follows practical patterns (valid emails, sensible ranges, ISO dates) while remaining privacy-safe.

Question 7

Can I customize fields and templates?

Accepted Answer

The initial version provides fixed templates (User, Product, Order). A custom template editor and more controls are planned in the roadmap.

Question 8

Is it fast?

Accepted Answer

Yes. Data generation runs entirely in the browser. Creating up to 100 records typically completes in under 500ms on modern devices.

Question 9

Which fields are included?

Accepted Answer

User includes id, name, email, age, createdAt. Product includes id, name, price, stock, tags, createdAt. Order includes id, userId, productId, quantity, total, status, createdAt.

Question 10

Will my data be uploaded or stored?

Accepted Answer

No. This tool does not upload or store your inputs or generated data. Everything is generated client-side.

Question 11

When should I use mock data?

Accepted Answer

Use mock data when you need fixtures for frontend development, API mocking, QA validation, database seeding, demos, or prototypes — especially when you cannot use production data.

Question 12

Why choose this tool?

Accepted Answer

It’s simple, fast, privacy-first, and exports both JSON and CSV. You can generate realistic test data instantly without installing libraries or writing code.
