Custom Field Mock Data Generator creates local browser-side test records by field rules and templates, helping teams move faster without exposing real business data.
What is mock data?
Mock data is synthetic data used instead of production records. It enables API integration, UI validation, and flow testing when backend services are unavailable or sensitive data cannot be used.
Key Features
- Define custom fields, types, ranges, and enum values.
- Export as JSON, CSV, SQL, XML, or YAML.
- Switch quickly with built-in template presets.
- Copy, download, and regenerate in one click.
Supported Field Types
Text Types
Generate generic strings, words, sentences, and paragraphs.
Numeric Types
Use number and range fields for amounts and counters.
Identity & Contact
Create names, emails, phones, and address-like values.
Structured Types
Include UUID, URL, IP, color, country, and city fields.
Common Scenarios
- Build API request and response samples for integration.
- Prepare realistic lists and detail pages for frontend demos.
- Seed database records for migration or rehearsal tasks.
- Prepare repeatable datasets for QA and regression testing.
Privacy
Field settings and generated records stay in your browser and are never uploaded to a server.
