Scale Your Testing with the Mock Data Generator
Streamline your development workflow with our free Mock Data Generator. Whether you need thousands of rows for database seeding or a quick JSON object for API prototyping, this tool generates realistic dummy data instantly. By utilizing modern JavaScript APIs, every byte of data is built locally in your browser, ensuring your test schemas and generated datasets never touch a remote server.
How to Generate Mock Data
- 01. Define Fields: Map out your data structure by selecting types like UUID, Name, or Email.
- 02. Configure Rows: Choose how many records you need—from a single entry to 10,000+ rows.
- 03. Select Format: Export your generated dataset in either CSV or JSON format.
- 04. Instant Download: Trigger the local generation engine and save the file directly to your device.
Frequently Asked Questions
Is there a limit to how many rows I can generate?
While the tool supports up to 10,000 rows, performance depends on your device’s memory. Because processing is local, it can handle large datasets without server timeouts.
Is my data really kept private?
Absolutely. This tool operates on a “Zero Server Load” architecture. No data is sent to a backend; all generation logic happens inside your browser.
What data types are available?
You can generate common data types including UUIDs, full names, email addresses, random numbers, and ISO dates.
Can I use this data for commercial projects?
Yes. The data generated is entirely synthetic and free for use in testing, presentations, or commercial software development.
Why should I use CSV over JSON?
CSV is ideal for spreadsheets and database imports (like SQL), while JSON is the standard for web APIs and modern application testing.
Does this tool require a login?
No. This utility is free to use with no account, login, or subscription required.
