demjson

I recently had the opportunity to try out demjson, a Python module that offers a variety of classes and functions for both encoding and decoding data. Its primary focus is on JSON format, which has become a popular choice as a simpler alternative to XML in Ajax web applications.

One of the standout features of this implementation is its commitment to adhering as closely as possible to the JSON specification (RFC 4627). Despite this commitment to standardization, demjson still offers a lot of flexibility to developers who want to use less-restrictive JavaScript syntax, thanks to a range of optional extensions.

Another impressive aspect of demjson is its ability to handle Unicode, including complete support for UTF-32, BOM, and surrogate pairs. This is an important consideration when working with data sets that contain non-ASCII characters.

Additionally, demjson is capable of supporting some of the more complex numeric types found in JavaScript, like NaN and Infinity, as well as the 'undefined' type.

One feature that I found particularly helpful was the lint-like JSON syntax validator. This tool offers a straightforward way to ensure that any JSON text used in my project is fully compliant with the JSON standard.

Overall, demjson proved to be an excellent choice for any developer looking to work with JSON data in a Python environment. Its adherence to standards, support for Unicode and complex data types, and syntax validation tools make it a valuable addition to any developer's toolkit.
