Korean Mock Data Generator

How it works

Build Korean-style mock member data for QA and fixtures—not generic English Faker output.

1. Pick row count (10, 50, 100)
2. Generate names, gender, age, 010 phones, name-based emails, jobs, companies, addresses, birth dates, join dates
3. Review in a scrollable table
4. Export in the same column order as the table via TSV copy, JSON copy, or UTF-8 BOM CSV

Everything runs in your browser only.

FAQ

Is this real personal data?

No. It's synthetic data. Do not load into production databases.

Excel encoding?

CSV includes UTF-8 BOM. If needed, use TSV copy-paste instead.

Which fields?

Name, gender, age, phone (010-XXXX-XXXX), email derived from a romanized name, occupation, company, Korean-format address, birth date, and join date.

Why Korean mock data instead of English Faker?

Most generic mock data tools output Western names and US phone formats. When you test a Korean signup flow, admin dashboard, or CRM import, you need 010 mobile numbers, Korean addresses (서울특별시, 경기도), and realistic surnames like Kim or Park. This tool fills that gap without installing libraries or exposing data to a server.

Can I paste into a spreadsheet or seed JSON?

Yes. Copy TSV keeps columns aligned with the table for Excel or Sheets. Copy JSON is an array of objects for API fixtures. Download CSV when you need a UTF-8 BOM file.

Can I use this for load testing?

Yes for UI demos and spreadsheet imports. For high-volume backend stress tests, generate once and reuse the CSV or JSON rather than hammering the browser with 100-row batches repeatedly.

Does Generate make a new set each time?

Yes. Clicking generate again (even with the same row count) rebuilds a fresh batch. The last row count is stored in this browser only so QA can resume at 50 or 100 without re-tapping the preset.
