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. 💪
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.
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
Once you have split the JSON file, you can import each smaller file using the
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:
Locate your MongoDB configuration file. By default, it is located at
/etc/mongod.confon Linux or macOS and
C:\Program Files\MongoDB\Server\version\bin\mongod.cfgon Windows.
Open the configuration file in a text editor.
Look for the line that starts with
maxBsonObjectSizeand increase the value to a larger number. For example, you can set it to
16777216(16MB) or higher:
maxBsonObjectSize = 16777216
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.
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. 💪🎉
