Jless, a command-line JSON viewer▲344
Hey, Hacker News! Today I'm proud to release jless, a command-line JSON viewer. jless provides a JSON viewing experience similar to what you see in a browser's network tab in the developer console, but from the comfort of your terminal, with a whole suite of vim-inspired key bindings to easily manipulate your view of the data and full-text regex search. I'm sure many of you have some piped together some combination of cat, jq and less before; hopefully jless can replace that usage (hence the name). It supports newline delimited JSON too, so it can handle any output from jq. I built jless to…

Datamorph – A clean JSON ⇄ CSV converter with auto-detect▲26
Hi everyone, I built a small web tool called Datamorph because I kept running into JSON/CSV converters that either broke with nested data, required login, or added weird formatting. Datamorph is a minimal, fast, no-login tool that can: • Convert JSON → CSV and CSV → JSON • Auto-detect structure (arrays, nested objects, mixed data) • Handle uploads or manual text input • Beautify / fix invalid JSON • Give clean, flat CSV output for real-world messy data It’s built with React + Supabase + serverless functions. Everything runs client-side except file parsing, so nothing is stored. I…
