About This Tool

This tool generates synthetic datasets from a user-defined schema, supporting numeric, categorical, and boolean features with configurable sample size. It enables reproducible experiments by allowing seed-based generation and the preservation of feature relationships through covariances or copulas. It also offers optional privacy controls to inject noise or apply DP-inspired adjustments. The generated datasets facilitate ML model training, ETL testing, and privacy-safe data sharing without exposing real records.
Conceptually, you define per-feature definitions (name, type, distribution parameters) and optional correlations; the engine draws samples from the specified margins and applies transformations to achieve the target distributions and relationships. Outputs include the dataset plus a detailed generation metadata block for auditability. The tool supports multiple export formats such as CSV, JSON, and Parquet, enabling easy integration with data science notebooks and pipelines.
Who benefits: data scientists, ML engineers, QA testers, and data engineers who need repeatable data, realistic distributions, and controlled privacy. Unique value stems from a schema-driven approach combined with reproducibility, provenance metadata, and privacy-aware options that can be tuned to project requirements. Core features include a schema editor, distribution templates, correlation controls, seed-based reproducibility, and export-ready formats for immediate reuse in modeling or testing scenarios.
Typical use cases include ML model prototyping, pipeline validation, and privacy-conscious data sharing for internal experimentation.

How to Use

Step 1: Define the feature schema (name, type, distribution parameters) and set the desired sample_size. Step 2: Optionally configure correlation structures and a seed for reproducibility. Step 3: Enable privacy options if required (noise or DP-inspired controls). Step 4: Run the generator to produce the dataset. Step 5: Inspect generated data and metadata; export in CSV, JSON, or Parquet as needed.

Frequently Asked Questions

Find Quick Answers

What export formats are supported?
Exports can be generated in CSV, JSON, or Parquet formats. Each format preserves data types and column names; large datasets may require chunked or incremental export depending on the backend implementation.
Can I model correlations between features?
Yes. You can supply a covariance matrix or use predefined correlation templates. If provided, the engine generates data that preserves the specified relationships; if not, features are generated independently unless a correlation model is defined.
How is privacy handled?
Privacy controls allow adding calibrated noise or applying differential-privacy-inspired adjustments. These options reduce exactness for sensitive attributes; they are not a guaranteed privacy solution and should be chosen with governance in mind.
Can a schema be reused across runs?
Yes. Save the feature definitions and seed value to reproduce identical datasets. Reproducibility depends on using the same seed and identical parameterization; metadata can be exported for audit trails.
