MongoDB Mock Data Generator (Supports ObjectId, ISODate, Native Shell Scripts)

Why MongoDB Developers Choose MockBlast

Most mock data generators output JSON that loses MongoDB's native data types. MockBlast generates true MongoDB shell scripts with proper type wrappers:

MongoDB-Specific Features

MockBlast understands MongoDB's document model and data types:

• •ObjectId Generation: Native 24-character hex ObjectIds wrapped with ObjectId() for _id fields and references.
• •ISODate Wrappers: Date and datetime fields wrapped with ISODate() to preserve MongoDB's Date type.
• •Shell Script Format: db.collection.insertMany([...]) syntax ready for MongoDB Shell or Compass.
• •Embedded Documents: Support for nested objects and arrays, perfect for MongoDB's flexible schema.
• •Type Preservation: Unlike JSON imports, MockBlast preserves MongoDB data types (ObjectId, Date, Number, Boolean).
• •Collection Names: Use your table names as MongoDB collection names automatically.

Example: MongoDB Schema with ObjectId and ISODate

CREATE TABLE users (
  _id VARCHAR(24) PRIMARY KEY,
  name VARCHAR(100) NOT NULL,
  email VARCHAR(100) UNIQUE NOT NULL,
  created_at TIMESTAMP DEFAULT NOW()
);

CREATE TABLE posts (
  _id VARCHAR(24) PRIMARY KEY,
  user_id VARCHAR(24),
  title VARCHAR(200),
  content TEXT,
  created_at TIMESTAMP DEFAULT NOW()
);

db.users.insertMany([
  { "_id": ObjectId("65a1b2c3d4e5f6789012345a"), "name": "John Doe", "email": "john@example.com", "created_at": ISODate("2024-01-15T10:30:00.000Z") },
  { "_id": ObjectId("65a1b2c3d4e5f6789012345b"), "name": "Jane Smith", "email": "jane@example.com", "created_at": ISODate("2024-01-16T14:20:00.000Z") }
]);

db.posts.insertMany([
  { "_id": ObjectId("65a1b2c3d4e5f6789012345c"), "user_id": ObjectId("65a1b2c3d4e5f6789012345a"), "title": "Getting Started with MongoDB", "content": "Lorem ipsum...", "created_at": ISODate("2024-01-17T08:15:00.000Z") }
]);

Common MongoDB Use Cases

How to Generate MongoDB Mock Data

1. 1.
   Import Your Schema: Paste your CREATE TABLE statement (or define fields manually). MockBlast detects _id fields and date fields automatically.
2. 2.
   Select MongoDB Format: Choose "MongoDB (JS Script)" from the format dropdown. MockBlast will generate shell scripts with ObjectId() and ISODate() wrappers.
3. 3.
   Set Document Count: Choose how many documents to generate. MockBlast handles everything from 10 documents to 1 million+.
4. 4.
   Download & Execute: Get MongoDB shell scripts ready to run. Copy and paste directly into MongoDB Shell (mongosh) or MongoDB Compass.
