Product overview
Data Assistant is a compact Windows utility that helps developers and testers create structured sample datasets quickly. Built using native Windows components, it installs with minimal footprint and runs responsively. The tool is suitable for creating both small example tables and very large datasets for prototyping or load-testing database scripts.
Output formats available
- JSON
- XML
- HTML
- CSV
- SQL
These export choices make it simple to drop generated data into different stages of a workflow or feed it directly into databases and applications.
Field configuration and data rules
- Control date values with custom format strings to match your application's expectations.
- Specify numeric ranges for integer or decimal fields to keep values realistic.
- Set exact lengths for string fields when fixed-width or specific sizes are required.
- Enable random generation modes to introduce variety across rows.
- Add optional prefixes and suffixes to fields for creating realistic identifiers or codes.
These settings let you tailor each column so the output mimics real-world data structures.
Advantages for development and testing
Data Assistant goes beyond manual copy-paste or simple mock data tools by producing varied, realistic records at scale. Key benefits include:
- Fast generation of datasets for rapid prototyping.
- Capability to create large volumes for stress and performance testing.
- Native Windows implementation for low resource overhead and quick responsiveness.
- Flexible exports and fine-grained field controls for seamless integration into test environments.
