Is my mock data private and compliant?

Yes. The Test Data Generator executes 100% locally in your browser memory using Web APIs and deterministic PRNG algorithms. Zero records or schemas are transmitted to external servers.

What is Deterministic Seed generation?

By locking a seed string (e.g. 'release-v2.4'), the generator produces the exact same randomized records every run. This is essential for reproducible unit tests, regression suites, and CI/CD pipelines.

Can I generate SQL table schemas (DDL)?

Yes. The studio automatically infers PostgreSQL, MySQL, SQLite, and MS SQL Server CREATE TABLE statements matching your exact column data types and constraints.

Test Data Generator

Advanced Mock & Test Data Generator Studio. Generate synthetic datasets with 45+ Indian and global field types, deterministic seed PRNG, and instant JSON, CSV, SQL DDL, NDJSON, and TypeScript exports.

How to Use Test Data Generator

Select an industry template (User Auth, E-Commerce, Indian KYC, API Logs) or build a custom schema in the Schema Builder.
Choose from 45+ field types including Indian PAN, Aadhaar, GSTIN, IFSC, UPI, UUIDs, IP addresses, and custom picklists.
Configure target output format (JSON, NDJSON, CSV, SQL multi-row batch, TypeScript, Markdown, XML, or YAML).
Set deterministic seed for reproducible integration test runs and adjust record volume up to 2,500+ rows.
Explore records in the Live Interactive Data Grid, copy formatted output, or download dataset files instantly.

Why High-Fidelity Mock Data Matters in QA & Development

Realistic synthetic test data prevents staging database pollution, protects sensitive customer PII under DPDP/GDPR regulations, and allows QA engineers to test edge cases, localized Indian formats (PAN, GSTIN, UPI), and high-concurrency API workloads safely.
