I am using the Python bson package which I'd prefer to use rather than have a pymongo dependencybut it doesn't explain how to read from a file.

That returned a list of dictionaries matching the JSON documents stored in that mongo collection. Try reading from the file, and passing the result to loads. Learn more.

Changed in version 2. This new format will be decoded to an instance of Timestamp.

The old format will continue to be decoded to a python dict as before. Encoding to the old format is no longer supported as it was never correct and loses type information.

This was the default encoding before PyMongo version 3. Consider using this for things like a web API, where one is sending a document or a projection of a document that only uses ordinary JSON type primitives.

In particular, the intInt64and float numeric types are represented in the native JSON number format. This output is also the most human readable and is useful for debugging and documentation.

Consider using this for things like testing, where one has to precisely specify expected types in JSON. In particular, the intInt64and float numeric types are encoded with type wrappers. Encapsulates JSON options for dumps and loads. Changed in version 3. The documentation for bson. Helper function that wraps json. Navigation index modules next previous PyMongo 3.

JavaScript objects are simple associative containers, wherein a string key is mapped to a value which can be a number, string, function, or even another object. This simple language trait allowed JavaScript objects to be represented remarkably simply in text:.

By virtue of being both human- and machine-readable, and comparatively simple to implement support for in other languages, JSON quickly moved beyond the web page, and into software everywhere.

JSON vs BSON

JSON quickly overtook XML, is more difficult for a human to read, significantly more verbose, and less ideally suited to representing object structures used in modern programming languages. MongoDB was designed from its inception to be the ultimate data platform for modern application development.

Languages that support any kind of complex mathematics typically have different sized integers ints vs longs or various levels of decimal precision float, double, decimal, etc. Not only is it helpful to be able to represent those distinctions in data stored in MongoDB, it also allows for comparisons and calculations to happen directly on data in ways that simplify consuming application code.

Second, each programming language has its own object semantics. Check your driver documentation to make sure you understand how to best access MongoDB BSON-backed data in your language to avoid confusion, and get the most out of your MongoDB experience.

BSON is designed as a binary representation of JSON data, with specific extensions for broader applications, and optimized for data storage and retrieval. JavaScript does not, for instance, differentiate between integers which are round numbersand floating-point numbers which have decimal precision to various degrees.

One of the big attractions for developers using databases with JSON and BSON data models is the dynamic and flexible schema they provide when compared to the rigid, tabular data models used by relational databases. Firstly, JSON documents are polymorphic — fields can vary from document to document within a single collection analogous to table in a relational database.

Documents make modeling diverse record attributes easy for developers, elegantly handling data of any structure. Secondly, there is no need to declare the structure of documents to the database — documents are self-describing. Developers can start writing code and persist objects as they are created. Thirdly, if a new field needs to be added to a document, it can be created without affecting all other documents in the collection, without updating a central system catalog and without taking the database offline.

When you need to make changes to the data model, the document database continues to store the updated objects without the need to perform costly ALTER TABLE operations — or worse, having to redesign the schema from scratch. Through these advantages, the flexibility of the document data model is well suited to the demands of modern application development practices.

While a flexible schema is a powerful feature, there are situations where you might want more control over the data structure and content of your documents. Most document databases push enforcement of these controls back to the developer to implement in application code. BSON types. Learn more. Atlas Fully managed cloud database.

Charts Native visualization for MongoDB data.Implementations of BSON exist for many different programming languages. Over time those libraries will be made more stand-alone, but they should be usable independently of MongoDB in their current state.

Most of these libraries use the Apache 2 license, but check individual project details to confirm. Used by the cross-platform libmongoc client library that provides a base for MongoDB drivers in higher-level languages. Even though the library is written in C, it can be used from higher level libraries such as Python and JavaScript through the use of GObject introspection.

If so, did you activate it properly before running the code? I tried installing bson using pip as admin. I'm working with virtualenv and i activate it before pip install. In your terminal try pip freeze in order to get a list of all 'pip-installed' packages and have a look whether pymongo is installed correctly.
