Test Data Generator

Create practical fixture records for development, demos, and QA. Generation happens in your browser; email addresses use the reserved example.test domain.

Data preset

Valid user profiles with unique reserved .test email addresses, roles, and account timestamps.

Number of records

Choose between 1 and 100 records.

Runs in your browser

Synthetic example values only: reserved email addresses, documentation-style phone numbers, placeholder locations, and non-real company names.

Create synthetic test data

Build small fixture batches for UI development, API examples, QA, demos, and database seeding. Test users provide account profiles; e-commerce customers add clearly non-deliverable address and order fields; CRM contacts include company and job details; API response data uses a status/count/data envelope; database seed records provide IDs, usernames, verification flags, and UTC timestamps.

Generation happens in the current browser page. Email addresses use the reserved example.test domain; phone numbers and addresses are documentation-style placeholders and must not be used for delivery. JSON preserves each preset shape. CSV and PostgreSQL SQL export tabular rows, including the data array for API response fixtures.

Frequently Asked Questions

Is the generated data real?

No. This tool creates synthetic example values locally. Emails use the reserved example.test domain, and phone and location values are documentation-style placeholders.

Is my data uploaded or saved?

No. Generation and formatting run in your browser. The tool does not send generated records to a server or store them for later.

What does each preset generate?

Test users includes account profiles and reserved .test emails; E-commerce customers adds synthetic non-deliverable address and order fields; CRM contacts includes company and role details; API response data wraps records in a status/count/data response object; Database seed records includes IDs, usernames, and UTC timestamps.

Which export formats are available?

You can view, copy, and download the current fixture as JSON or CSV, or as PostgreSQL INSERT statements. CSV and SQL export the record rows; for the API response preset, those formats export the data array.

How many records can I generate?
