Generate realistic mock data for testing an app, API or database — pick the fields you need, choose how many records, and export the result as JSON, CSV or XML. Built for developers and creators who need quick test datasets without setting up a backend.
Whenever you're building or testing something that needs data — an app, a dashboard, an API integration — you don't want to use real user information. This tool generates realistic-looking but completely fake data so you can test layouts, pagination, filters and API responses without touching production data.
Everything is generated locally in your browser using random name, email, address and company pools — nothing is fetched from an external API, so it works instantly and repeatedly.
Step 1 — Choose your record count. Enter anywhere from 1 to 100 records depending on how much test data you need.
Step 2 — Select the fields you want. Tick the fields relevant to your test case — name and email are common, but add address, company, date or boolean flags as needed.
Step 3 — Pick your export format. Choose JSON for APIs and JavaScript testing, CSV for spreadsheets and imports, or XML for legacy systems — then copy or download the result.
Generating way more data than you need. Large record counts can slow down your test environment for no benefit — start small (10–20 records) and scale up only if needed.
Using mock data in production by accident. Always double check that test datasets generated here don't accidentally get committed or deployed as if they were real records.
Picking the wrong format for your use case. CSV won't preserve nested structures the way JSON does — if your API expects JSON objects, don't convert everything to CSV first.
Completely fake. Names, emails, phone numbers, addresses and companies are all randomly generated for testing purposes only and don't belong to real people.
Up to 100 records per generation. If you need more, generate multiple batches and combine them, or download and merge the files.
Yes — that's exactly what it's built for. Copy the JSON, CSV or XML output directly into your test suite, mock server or seed scripts.
No. All data generation happens locally in your browser — nothing is uploaded or stored on a server.
Testing against real user data is risky and often against privacy regulations. Mock data lets you build and demo features, test pagination and edge cases, and share sample payloads with teammates — all without exposing anything sensitive.
