Free Synthetic Person Data Generator

01 · Definition

What is synthetic person data generator?

A synthetic person data generator creates fictional person profiles for software testing, QA and product demos. Spotzee's free synthetic person data generator returns localised names, gender, birth dates and ages, with optional middle names, prefixes, suffixes, job details, biographies, gender identity and zodiac signs when you choose those fields.

The tool above sends your count and selected options to the Spotzee Extended API, then renders the returned persons[] records. Read the in-depth person data generator guide for integration patterns, locale support and ways to combine person data with contact, name and date generators.

How it works

1. 1Enter a count.Type the number of person records to generate, from 1 to 100.
2. 2Choose a locale.The locale controls name style; use locale codes such as en, es, fr, de, pt_BR or zh_CN.
3. 3Pick profile fields.Turn optional fields on or off for job title, job details, biography, middle name, prefix and suffix, gender identity and zodiac sign.
4. 4Use a seed.Enter a numeric seed when you need the same request to reproduce the same generated records.
5. 5Generate records.The proxy route validates the request, forwards it to the Spotzee Extended API and renders the returned records in the result panel.

03 · Risk

Why it matters

Production records do not belong in development databases, demo screens or automated test fixtures. Synthetic person data gives your team realistic profiles without copying customer names, dates of birth or profile attributes into places where they are harder to control.

Hardcoded names like "John Doe" hide layout, sorting and validation problems. Localised records with optional middle names, prefixes, suffixes and profile fields create better fixtures because they exercise longer strings, diacritics, optional fields and deterministic test runs.

04 · Use cases

Common ways to use this tool

• Test database seeding. Use it as a test person data generator, then bulk-insert 50 to 100 records into a test database to exercise pagination, search and filtering logic.
• Prototype UI population. Use the output as a sample person data generator for UI mockups so reviewers see realistic names, ages and optional job fields.
• Automated test fixtures. Use a numeric seed to generate repeatable person records for tests that need stable expected values.
• Profile-field coverage. Turn optional fields on in this synthetic data generator to test whether importers, schemas and UI rows handle missing and present profile attributes correctly.
• Locale handling. Generate non-English records to test Unicode storage, sorting and search before real customer data reaches the workflow.

05 · Interpretation

What to check in the result

• Count outside 1–100. The API accepts between 1 and 100 records per request. For larger datasets, call the endpoint multiple times via the Extended API.
• Blank locale. A blank locale defaults to en. Enter a locale code when you need language-specific names or character coverage.
• Wrong optional-field shape. If a downstream schema expects job details or personal details, enable the matching toggles before copying results into your test fixture.
• Invalid seed. Seeds must be whole numbers. Leave the field blank for random output, or reuse the same seed for deterministic test data.
• Age-specific tests. The person endpoint returns generated birth dates and ages. For strict age ranges, combine it with the date generator's birthdate methods.
