In plain words

Weird JSON is a software tool that handles unusual or non-standard JSON data formats. Launched in 2022, it is designed for developers and data engineers who work with malformed, unconventional, or edge-case JSON structures. The tool focuses on parsing and processing JSON that doesn't conform to typical standards, making it useful for debugging, data transformation, and handling legacy systems with quirky data formatting requirements.

    I'm working on a tool that will probably involve querying JSON documents and I'm asking myself how to expose that functionality to my users.

Has anyone here been in a similar situation? Which tool / language did you end up exposing to your users?

    History: Last year I had to replace the tire on my bike, and I was surprised how difficult it was to find a suitable new tire. There were a lot of numbers written on the casing, so I googled what they meant. In the end I was successful, but I didn't want to do the same work again for the next bike after I've forgotten the details. So I wrote this website. Technically, the web page is kept very simple, no frameworks, no templates, no website builder. It uses HTML5, CSS and JavaScript, and it privides a responsive layout for mobile usage. I'm happy to receive feedback. If you have tried the…
