JSON is not JSON Across Languages
October 2, 2025
JSON (JavaScript Object Notation) was designed as a simple, lightweight, and human-readable data interchange format, often positioned as a more accessible alternative to XML. It has become the de facto standard for web APIs and system integration. However, while the specification itself is straightforward, different programming languages and libraries can interpret certain aspects of JSON differently. What appears to be a uniform format can, in practice, lead to subtle inconsistencies, edge cases, and implementation details that developers need to be aware of when working across diverse platforms.
So we’re certain that any front-end developer will use JSON as part of their workflow. So it’s worth this reminder that JSON can have subtle inconsistencies between different platforms.
