I've been working on a browser-based JSON tool that supports a query language with dot notation, array slicing, wildcards, and recursive descent (..key). It also auto-generates TypeScript interfaces from your data. Everything runs client-side — your data never leaves the browser. The entire app is a single HTML file with zero dependencies. You can compress your JSON + query into a shareable URL, which is useful for bug reports or sharing API response structures with teammates. Would love feedback on the query syntax and anything else. https://json.express
