Mock Data Generator
Build a schema, generate up to 100,000 rows, and export instantly.
| Column name | Data type | |
|---|---|---|
How it works
- 1
Build a schema
Add fields one at a time and pick a data type for each — names, emails, numbers, dates, booleans, and more.
- 2
Choose how many rows
Set the row count you need, from a handful for a quick UI mockup to thousands for load-testing a real dataset.
- 3
Generate and export
Data is generated instantly in your browser and can be exported as CSV or JSON — nothing is uploaded to a server.
Frequently asked questions
Is the generated data really random, or does it come from a real dataset?+
It's procedurally generated using randomization and pattern templates for each field type (e.g. realistic-looking names and emails) — it doesn't pull from or expose any real person's data.
Is there a limit to how many rows I can generate?+
Generation happens entirely in your browser, so the practical limit is your device's memory rather than a fixed cap. Very large row counts (hundreds of thousands+) may take longer or slow down the browser tab.
What can I use mock data for?+
Common uses include populating a UI during development, seeding a test database, load-testing an import pipeline, or building demos without using real customer data.
Does any of my schema or generated data get sent to a server?+
No — schema building and data generation both run client-side in your browser. Nothing you configure or generate is uploaded anywhere.
