📊 Mock Data Generator
Generate structured test data in JSON, CSV, or SQL formats. Supports Swiss localization (ZIP, canton, phone) and custom fields.
Configuration
No custom fields defined. Create new fields above with any data types.
Generated Data
The generated datasets will be displayed here.
Swiss Templates (de-CH)
By enabling Swiss localization, ZIP codes, cantons, street names, and mobile numbers (e.g. +41 79 ...) are generated in the country-specific format. The generated test data is excellent for testing Swiss webshops, CRM systems, and forms.
Guide & best practices
Mock Data Generator for test data and prototypes
Quickly create structured test data for development, demos and load tests – with schema, locale and reproducible seed.
Typical use cases
Useful for UI prototypes, API mocking, database seeds, performance tests and demo datasets.
How Balou generates test data
Define fields and types, choose count, locale and output format; Balou generates the data locally, optionally with a seed.
Test data best practices
Use realistic field types, a seed for reproducible datasets and the right output format for your import.
Frequently asked questions
Which field types are available?
Typical types are name, email, uuid, date, number and boolean; combine them into a schema.
How many records and which format?
You choose the count (e.g. 100 rows) and the format JSON, CSV or SQL to match the target system.
Is the data reproducible?
Yes, with a fixed seed you regenerate the same dataset for the same settings.
Does the data contain real people?
No, the values are synthetic – do not use them as real personal data.
