How to Convert CSV to BSON - Step by Step Guide

Step 1

Input Your CSV Data

Let's convert your CSV data to BSON format! Whether you're preparing spreadsheet data for MongoDB imports, working with database exports, or optimizing storage, you have several convenient options:

•
Paste directly: Copy your CSV data from Excel, databases, or data exports
•
Upload a file: Click "Upload" to select a .csv or .txt file from your computer
•
Try the sample: Click "Sample" to load example CSV and see the BSON conversion

Example: CSV Input

Here's a typical CSV structure ready for BSON conversion:

id,name,email,age,department,isActive
1,Robert Wilson,[email protected],30,Engineering,true
2,Jane Smith,[email protected],28,Marketing,true
3,Mike Johnson,[email protected],35,Sales,false
Step 2

Configure Parsing Options

Customize how your CSV is parsed and converted to BSON binary data:

•
Header handling: Choose whether first row contains column names for proper data mapping
•
Custom delimiters: Support for comma, semicolon, tab, or pipe separators
•
Output format: Choose Base64 (compact) or Hex (debug-friendly) encoding for the BSON binary data
•
Automatic conversion: CSV automatically converts to JSON first, then encodes to BSON with MongoDB-specific type optimization

Example: BSON Output (Base64)

The same CSV, now encoded as BSON in Base64 format:

Step 3

Export Your BSON Data

Get your encoded BSON ready for MongoDB! Multiple export options make integration seamless:

•
Copy to clipboard: One-click copying for quick pasting into MongoDB Compass or application code
•
Download as .bson: Save binary file for direct use with mongorestore and MongoDB imports
•
Ready for MongoDB: Optimized binary format with proper type information for efficient database operations

Frequently Asked Questions

How do I convert CSV to BSON for MongoDB?

Simply paste your CSV data into the converter, configure parsing options (headers, delimiter), choose your preferred output format (Base64 or Hex), and the tool automatically converts CSV to JSON first, then encodes it to BSON. The converter handles all MongoDB-specific data types including ObjectId, Date, and Binary.

What's the difference between Base64 and Hex output?

Both represent the same BSON binary data as text. Base64 is more compact and commonly used for APIs and web transmission. Hex is easier to debug byte-by-byte and useful for development and troubleshooting.

How do I import the BSON into MongoDB?

Download the .bson file and use mongorestore to import it, or copy the encoded BSON and use MongoDB drivers to insert documents programmatically into your database.

Does the converter support different CSV delimiters?

Yes! The converter supports comma, semicolon, tab, and pipe delimiters. You can also handle quoted fields containing delimiter characters. The tool automatically detects and handles various CSV formats commonly used in Excel and database exports.

Can I convert large CSV files to BSON?

Yes! The converter handles large CSV files efficiently. All conversion happens in your browser for maximum privacy, and there are no file size limitations or conversion frequency restrictions.

Is this CSV to BSON converter free?

Yes, completely free with unlimited conversions. No registration required, and you can convert as much CSV to BSON as needed. All processing happens locally in your browser for security and privacy.
