AI Analysis

Compress JSON and queries into shareable URLs for bug reports.

Strengths

•Single HTML file with zero dependencies is impressive engineering
•Shareable URLs with compressed state useful for team debugging
•Auto-generate TypeScript interfaces from JSON structures

Weaknesses

•JSON viewers are extremely crowded (JSONLint, JSON Crack, many others)
•Query syntax competes with established jq and JSONPath

Post Description

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
