Main Functions

Windows Native

Data Assistant uses Windows Native technology, which ensures that the software has a small installation size and high response speed

Quickly Generate

Create small or large data sets for rapid prototyping or stress testing of tables, structures and scripts

real data

Generate large, heterogeneous, real-world data for any development, testing or demonstration purposes instead of creating repetitive impractical text fields just by copying and pasting

Document Based

The data structures you create are preserved intact and different datasets can be created for different purposes

Export Data

Can export JSON, SQL, CSV, HTML, XML, and convert data structures into Java, C#, TypeScript, and JSONSchema codes

Field Fine-tuning

You can use optional prefixes and suffixes for any field; fill the field with random data, specify the length or length range; specify the range for numeric fields; use format strings for date ranges to determine the output content
