Product definition
Scoped a common developer pain point into a complete utility that could be designed, tested and documented in one day.
Open Source / Developer Tools / Daily Build
JSON Lens
/ Overview
A local-first JSON inspector that validates, formats, minifies and turns nested data into searchable paths.
Raw JSON becomes difficult to scan when data is deeply nested, and parser errors rarely make the broken location easy to understand.
/ Provided servicesClear thinking.
Clear thinking.
Practical delivery.
Interface design
Created a soft, high-contrast workspace with clear input, output, status and path-explorer regions.
Engineering
Separated recursive parsing and search logic from browser behavior and tested it with Node's built-in test runner.
/ Solution
I built a dependency-free browser tool that keeps data local, reports friendly line and column errors, formats or minifies valid JSON and flattens values into searchable paths.
/ Impact
Local-first with no data uploads
Five automated logic tests
Searchable nested JSON paths
Responsive accessible interface
JavaScript modules
Pure functions for parsing, formatting, minifying, recursive traversal, summaries and search.
HTML & CSS
Semantic controls, responsive panels, accessible status feedback and a dependency-free interface.
Node test runner
Five tests covering valid and invalid JSON, nested paths, unusual keys, filtering and type summaries.
