About Synthetic Data Studio

Synthetic Data Studio is a free synthetic data generator for developers, QA teams, product managers, and demo builders who need realistic test data without using real customer information. Generate fake PII, masked identity fields, dummy KYC records, medical-style records, fintech transactions, e-commerce customers, HR profiles, SaaS workspaces, and API mock data.

Everything runs locally in your browser, so generated data is never uploaded to Kitpace. Build a schema, choose a locale, add masked or unique fields, preview rows, and export test datasets as JSON, CSV, XLSX, SQL inserts, NDJSON, XML, YAML, Markdown, plain text, or API response payloads.

API-ready datasets

Export mock API response payloads, NDJSON streams, JSON arrays, SQL seed data, CSV files, and XLSX workbooks.

Custom schema builder

Generated data is synthetic and created in your browser. No dataset is uploaded, logged, stored, or sent to a server.
