ماذا تفعل Mock Data Generator؟
Mock Data Generator يتيح إنشاء النتائج مباشرة في المتصفح مع شرح واضح للنتيجة والحدود. القدرات المتحقق منها: Seven field types, Seeded reproducible generation, English or Chinese data, JSON and CSV exports.
When should you use this tool?
Use this tool to create reproducible fixtures and sample tables. Use the existing UUID or Password Generator for cryptographic randomness; use an API schema to define production constraints.
كيف تستخدمها؟
- Define 1–30 unique field:type lines, for example id:uuid and name:fullName.
- Choose a count of 1–5000, an integer seed, data language, and output format.
- Select Run, inspect the generated records, and download JSON or CSV.
مثال فعلي للإدخال والإخراج
Generate typed boolean test records
الإدخال
Fields: active:boolean
Count: 3; seed: 42; language: Englishالإخراج
[
{"active": true},
{"active": false},
{"active": false}
]Boolean fields remain JSON booleans. The adopted Faker version and seed determine the sequence; check actual output when changing versions.
أخطاء شائعة وطرق الإصلاح
| العرض | السبب المحتمل | الإصلاح |
|---|---|---|
| A field definition is rejected. | The type is unsupported, a field name repeats, or the name is reserved. | Use unique field names and uuid, fullName, email, integer, boolean, company, or word. |
| A saved seed produces different results later. | The locale, field order, generation settings, or library version changed. | Keep all settings and the pinned Faker version together with the fixture. |
Supported behavior and limitations
حدّ محدد لهذه الأداة: Generated values are synthetic test data and do not establish valid identities or deliverable email addresses. Integer fields range from 0 to 100. CSV converts cells to text and prefixes formula-like strings with an apostrophe; review imports in the target spreadsheet. Do not use seeded UUIDs as production secrets.

Mock Data Generator — FAQ
Is my input uploaded?
No. Processing happens in a browser Worker. Engine files load from this website; tool input, output, and filenames are not sent to a processing API.
Do I need an account or API key?
No account, API key, or backend processing service is needed.
How do I save a result?
Review the result, then use the Copy or Download control available for that output. Modifying input clears stale results.
What are the limits?
Generated values are synthetic test data and do not establish valid identities or deliverable email addresses. Integer fields range from 0 to 100. CSV converts cells to text and prefixes formula-like strings with an apostrophe; review imports in the target spreadsheet. Do not use seeded UUIDs as production secrets.
