Opening a BSON File

The BSON file type is primarily associated with MongoDB.

BSONFile Extension BSON
File extension: BSON
File type:  binary serialization file

What is a BSON file

BSON files mostly belong to MongoDB. BSON files are binary files that store JSON-like documents. They use a Binary JSON format to keep data in a compact, machine‐readable form.
These files are mostly used by MongoDB to save and retrieve structured data. The format encodes data types and lengths so that applications can quickly traverse the data.
Other uses include storing log data from tools like Sysmon, where a similar binary JSON serialization is applied.
To view a BSON file, you need a conversion tool since a basic text editor cannot display it in a clear format. Below are some tips on handling these files:

  • Use the bsondump utility that comes with MongoDB to convert BSON into human-readable JSON.
  • Apply programming libraries (for example, in Python or JavaScript) that can decode BSON.
  • Avoid editing the file manually to prevent data corruption.

How to open BSON files

You need a suitable software like MongoDB to open a BSON file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your BSON file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a BSON file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert BSON files:

  1. MongoDB
    See the previous paragraphs to learn more about the main application. BSON files are often referred to as MongoDB databases because this type of file is primarily created or used by this software.
  2. BSON (source code file) by MongoDB
    BSON stands for Binary JSON. It is the binary encoded version of JSON (JavaScript Object Notation) files and was created for MongoDB. JSON is an open-standard data interchange format that was derived from JavaScript, but is language-independent. JSON is used in a wide range of applications, such as replacing XML in AJAX systems. The difference between JSON and BSON is that BSON is easy to traverse, takes up less storage space and is faster. However, in some cases, owing to length prefixes and explicit array indices, BSON becomes less efficient in storage space.

BSON file format details:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So you need a detailed analysis of a file to find out the format and the associated program. Below you will find our evaluation of the BSON files:

The BSON extension is very commonly found and mainly uses a special format. However, the following two file formats are common:

All other BSON files (18%) have different formats, the following 9 formats can be found: GZIP, JSON, name, storage and staff. These files sometimes refer to bytes, profile, info, settings, account or message. If you want to find out which format your BSON file belongs to, just click on the button "Choose your .bson file to analyze".

How to solve problems with BSON files

  • Associate the BSON file extension with the correct application.
  • Update your software that should actually open binary serialization files. Because only the current version supports the latest BSON file format. Search, therefore, e.g. on the manufacturer website after an available MongoDB update.
  • To make sure that your BSON file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
