How to Validate BSON - Step by Step Guide

Step 1

Input Your BSON Data

Let's validate your BSON data! Whether you're working with MongoDB exports, checking data integrity, or debugging import issues, you have several convenient options:

•
Paste directly: Copy your BSON data in Base64 or Hex format from MongoDB exports, mongodump, or binary data tools
•
Upload a file: Click "Upload" to select a .bson or .bin file from your computer
•
Try the sample: Click "Sample" to load example MongoDB document and see how validation works

Example: BSON Input (Base64)

Here's what encoded BSON data looks like:

Step 2

Automatic Validation & Analysis

The magic happens instantly! As soon as you input BSON data, the validator automatically:

•
Validates integrity: Checks binary structure and ensures BSON is well-formed
•
Detects MongoDB types: Identifies ObjectId, Date, Binary, Decimal128, Timestamp, and other special types
•
Analyzes structure: Shows document size, field count, and nesting levels for complexity assessment

Example: Validated & Decoded Output

The same BSON, now validated and shown as readable JSON:

{
  "_id": {
    "$oid": "6738b6e7ab000000000000000"
  },
  "name": "Alice Johnson",
  "email": "[email protected]",
  "age": 32,
  "salary": 95000,
  "isActive": true
}
Step 3

Export Your Validated Data

Get your validated BSON data ready for use! Multiple export options make it easy to integrate into your workflow:

•
Copy to clipboard: One-click copying of validated JSON for quick pasting into MongoDB Compass, applications, or documentation
•
Download as JSON: Save the validated output as a .json file for debugging, analysis, or sharing with your team
•
View validation stats: See document size, field count, nesting levels, and detected MongoDB types at a glance

Frequently Asked Questions

How do I validate BSON data from MongoDB?

Simply paste your BSON data in Base64 or Hex format into the validator, or upload a .bson file directly from mongodump exports. The tool automatically validates structure and shows detailed analysis.

What's the difference between Base64 and Hex format?

Both are just different text encodings of the same binary BSON data. Base64 uses A-Z, a-z, 0-9, +, / characters and is more compact. Hex uses 0-9, A-F and is easier to debug byte-by-byte. The validator accepts both formats.

What MongoDB data types are detected?

The validator automatically detects all MongoDB-specific types including ObjectId, Date, Binary, Decimal128, Long, Timestamp, RegExp, MinKey, and MaxKey. Each detected type is displayed as a colored tag in the validation results.

Can I export the validated BSON data?

Yes! After validation, you can copy the decoded JSON to clipboard or download it as a .json file. The output preserves all MongoDB data types in Extended JSON (EJSON) format for compatibility with MongoDB tools.

Does the validator fix corrupted BSON?

The validator identifies BSON errors and shows precise error messages but doesn't auto-fix corrupted data. It helps you understand what's wrong with the binary structure so you can correct the issue at the source.

Is the BSON validator completely free?

Yes, totally free with no limitations on file size, usage frequency, or features. No registration required, and you can validate unlimited BSON files. All validation happens in your browser for maximum privacy.
