What is Mock Data Generator?
Development, integration and demos all need large amounts of realistic-looking test data. Define field names and types (Chinese names, phone numbers, emails, UUIDs, dates, IPs, English sentences — 13 types in total), generate up to 1000 rows at once, and export as JSON or CSV ready to import into a database. All data is generated randomly on your device and contains no real personal information, so it is safe for test environments.
How to Use
- Add fields and choose their types
- Set the number of rows
- Export as JSON or CSV
FAQ
- Are the generated phone numbers and names real?
- No. Everything is randomly assembled fake data that maps to no real person — safe for testing.
- How many rows can I generate at once?
- Up to 1000 per run; generate multiple batches and merge them for larger datasets.
