json.fun
Updated Nov 18, 2022
An online formatter for JSON and XML. I started with the domain name and had more ambitious plans for it, but as is often the case with hobby projects, they never materialized.
Still, it has a single (somewhat unique) feature: it can auto-complete truncated JSON. At a previous day job, we had a request log table with columns that were rarely large enough to contain the entire payload, and trying to manually close partial JSON is a pain, so json.fun can do that for you.
The app used to be written in Vue, but later helped me learn some React/Redux, and I then rewrote it (again) in plain JS with RxJS, before converting it to TypeScript.
