Mongoimport of JSON file

😎 How to successfully import a JSON file into MongoDB using mongoimport 😎

So you have a JSON file ready to be imported into your MongoDB database using the mongoimport command. 🚀 But when you run the command, you encounter an error message. 😱😱 Don't worry, we'll help you troubleshoot the issue and get your JSON file imported smoothly into MongoDB. 💪

The Problem

Based on the error message you shared, it seems like the JSON file you're trying to import has a size larger than what MongoDB can handle. 📏 This can be due to various reasons, such as a very large number of records or the presence of large fields in the JSON file.

The Solution

To solve this problem, you have a couple of options:

1. Split the JSON file into smaller chunks

If your JSON file is very large, you can split it into smaller files before importing. 💔 You can use any text editor or command-line tools to split the file into multiple smaller files. For example, if your original file is fileName.json, you can split it into smaller files like part1.json, part2.json, etc.

Once you have split the JSON file, you can import each smaller file using the mongoimport command:

mongoimport --db dbName --collection collectionName --file part1.json
mongoimport --db dbName --collection collectionName --file part2.json

By importing the JSON file in smaller chunks, you can avoid exceeding MongoDB's size limitations.

2. Increase the MongoDB document size limit

If splitting the JSON file is not an option, you can increase MongoDB's document size limit by modifying the maxBsonObjectSize parameter in your MongoDB configuration file. 🛠️

Here's how you can do it:

1. Locate your MongoDB configuration file. By default, it is located at /etc/mongod.conf on Linux or macOS and C:\Program Files\MongoDB\Server\version\bin\mongod.cfg on Windows.

2. Open the configuration file in a text editor.

3. Look for the line that starts with maxBsonObjectSize and increase the value to a larger number. For example, you can set it to 16777216 (16MB) or higher:

   maxBsonObjectSize = 16777216

4. Save the configuration file and restart MongoDB for the changes to take effect.

With the increased document size limit, you should be able to import the JSON file without encountering the error.

Conclusion

Importing a JSON file into MongoDB using mongoimport might hit a roadblock if the file size exceeds MongoDB's limitations. But fear not, as we showed you two viable solutions to overcome this problem. Now you can successfully import your JSON file and start working with your data in MongoDB. 💪🎉
