How to Insert a JSON Document into MongoDB Using C#

When working with data management in applications, developers often need to move data from various sources, such as CSV files, into databases like MongoDB. In this guide, we will tackle the challenge of reading employee information from a CSV file, modifying it into the required JSON format, and then inserting this JSON into a MongoDB collection using C# .

Understanding the Problem

Here's the scenario: you have a simple CSV file that contains names and employee IDs, and you want to update this information in a predefined JSON structure before sending it to your MongoDB database.

For example, you may have a CSV file that looks like this:

Your target JSON format is structured as follows:

As seen here, you want to populate this JSON object with the data extracted from the CSV.

Step-by-Step Solution

Prerequisites

MongoDB Driver for C# - Make sure the MongoDB driver is installed in your C# project. You can add it via NuGet:

Connection Details - Have your MongoDB connection string and database name ready.

Code Snippet for Inserting Data

Below is a practical C# code snippet that reads the CSV data, constructs the JSON document, and inserts it into your MongoDB collection:

Explanation of the Code

Read CSV File: A function ReadFromCsv is assumed (you would need to implement this) that reads the CSV file and returns the name and employeeId.

MongoDB Client:

Creating the Document:

We create a BsonDocument which matches the required JSON structure. Note that we ensure the employee name is lowercased to match the original request.

Inserting the Document:

Finally, we use InsertOneAsync to add the document to the MongoDB collection.

Final Thoughts

With this simple implementation, you can effectively transfer data from a CSV file into your MongoDB database as a well-structured JSON document. This approach can be expanded and tailored to handle larger datasets or more complex structures as needed.
