Xardas Mock Data

Offline mock-data generator for developers — schema in, JSON, CSV, or SQL out.

Xardas Mock Data is a native Windows desktop application for developers who need realistic test data without sending anything to the cloud. Define a schema field by field, choose a row count, preview the generated data live, and export it as JSON, CSV, or SQL INSERT statements ready to drop into a database, a fixtures file, or an API mock.

It supports 29 field types — names, emails, dates, UUIDs, IP addresses, enums with your own choices, auto-incrementing IDs, and more. Turn on a fixed seed and the same schema produces byte-identical rows every time, which suits deterministic fixtures and CI. Save schemas you reuse as named presets. Everything runs on your machine: no accounts, no cloud services, and your presets stay in a local file.

What it does

  • Schema editor: add, remove, and reorder fields, each with a name, type, and contextual options, with a live preview table
  • 29 field types including full_name, email, int/float ranges, date/datetime, uuid, city, country, enum, increment_id, ip_address, and url
  • Export to JSON, CSV, or SQL INSERT statements, with SQL table names sanitized and the batch wrapped in BEGIN/COMMIT
  • Fixed-seed mode produces byte-identical, reproducible output for deterministic test fixtures and CI
  • Reusable named presets, with three starter schemas (Users table, E-commerce orders, IoT sensor readings)
  • Runs as a native local app with no accounts or cloud services; saved presets persist in a local file

  • 14-day refund if it doesn't work as described — Refund Policy
  • Instant download, delivered by email — re-download anytime from your receipt
  • No subscription and no account. After a one-time online activation on first launch — the app checks your license key with the marketplace you bought it from — it runs on your own computer with no periodic license checks and no telemetry, and keeps working even if this website disappears.
  • Your license covers up to three activated installations at a time. You can release an installation from inside the app to free a slot for another one. Licensing requires Internet access only when activating or releasing an installation. Optional product features may use the network as separately disclosed for that product — for Xardas Mock Data, see the next point.
  • Other than licensing activation and release, Xardas Mock Data makes no network connections — your data stays in a local file on your machine, with no cloud and no tracking.
