Data & Code Tools is maintained by a solo developer building practical browser-based utilities for format conversion, API testing, regular-expression debugging, XML transformations, and temporary mock APIs.
The site intentionally keeps the core tools lightweight and direct. Most tools run fully in your browser; server-side features are used only where they are needed, such as API proxying and temporary mock endpoints.
