Export
JSON and CSV exports are plain downloads. SQL export writes INSERT statements for your table name.
About this tool
IconVault's API Mock Generator creates realistic fake data for development and testing. Design a schema from typed fields, including full names, emails, phones, UUIDs, integers, floats, booleans, dates, lorem text, hex colors, IP addresses and URLs, choose how many rows you need, and generate a full dataset in one click, exportable as JSON, CSV or SQL insert statements.
Generation uses a seeded random generator, so the same seed always reproduces the same dataset, which is ideal for repeatable tests and shared fixtures. Everything runs 100% client-side with nothing uploaded, and it is free to use. The honest boundary: this is synthetic data for dev, QA and demos, not real personal data and not for production use.
