Python MongoDB - insert_many Query

Last Updated : 12 Jul, 2025

In MongoDB, insert_many() method is used to insert multiple documents into a collection at once. When working with Python, this operation is performed using the PyMongo library.

Instead of inserting documents one by one with insert_one(), insert_many() allows developers to pass a list of dictionaries, where each dictionary represents a document. This is a more efficient and cleaner approach when inserting bulk data into MongoDB.

collection.insert_many(documents, ordered=True, bypass_document_validation=False, session=None, comment=None)

Parameters: 

• documents (Required): A list of documents (dictionaries) to insert..
• ordered (Optional, default=True): If True, stops inserting if one fails. If False, tries to insert all.
• bypass_document_validation (Optional, default=False): If True, skips any validation rules.
• session (Optional): Used for advanced tasks like transactions.
• comment (Optional): Adds a note to the operation (from PyMongo v4.1).

Now, Let's explore some Examples:

In the below code, multiple student records are inserted with predefined _id values into a collection.

from pymongo import MongoClient

client = MongoClient("mongodb://localhost:27017/")
db = client["GFG"]
collection = db["Student"]

# List of student documents to insert
students = [
    { "_id": 1, "name": "Vishwash", "roll_no": "1001", "branch": "CSE" },
    { "_id": 2, "name": "Vishesh", "roll_no": "1002", "branch": "IT" },
    { "_id": 3, "name": "Shivam", "roll_no": "1003", "branch": "ME" },
    { "_id": 4, "name": "Yash", "roll_no": "1004", "branch": "ECE" }
]

# Inserting the documents into the collection
collection.insert_many(students)

Output:

In this example _id is not provided, it is allocated automatically by MongoDB.  

from pymongo import MongoClient 
# Connect to MongoDB
myclient = MongoClient("mongodb://localhost:27017/")

# Access the database and collection
db = myclient["GFG"]
collection = db["Geeks"]

# List of documents to be inserted
mylist = [
    {"Manufacturer": "Honda", "Model": "City", "Color": "Black"},
    {"Manufacturer": "Tata", "Model": "Altroz", "Color": "Golden"},
    {"Manufacturer": "Honda", "Model": "Civic", "Color": "Red"},
    {"Manufacturer": "Hyundai", "Model": "i20", "Color": "White"},
    {"Manufacturer": "Maruti", "Model": "Swift", "Color": "Blue"},
]

# _id is not specified; MongoDB will assign unique ObjectId to each document
collection.insert_many(mylist)

Output
