Creating fake datasets for system testing or software prototyping can expose schemas when using online tools. OmniTool Hub's Mock Data Generator lets you design schemas, choose column types, and generate up to 50,000 rows of mock data entirely in browser memory.
Schema Builder & Compiler
Here is a detailed breakdown of the capabilities, algorithms, and configurations available within this tool suite:
1. Schema Designer Grid
Schema Design
Add columns, define header fields, and select data types (names, emails, dates, numbers, phone numbers, UUIDs).
2. Bulk Generator Options
Generation
Configure target row counts and choose output formats (JSON array of objects or flat CSV strings).
💡 Pro-Tip on Security & Utility:
Data generation runs inside local browser memory streams, allowing you to generate large datasets offline without server lag.
Step-by-Step Usage Guide
- Define column headers and select target data generator types in the designer grid.
- Set your desired row count (supports generating up to 50,000 rows).
- Choose output formats (**JSON** or **CSV**).
- Click **Generate Data** and download the generated file.
