Show HN: A macOS app for data refinement

3 points by jshchnz 25 days ago · 0 comments · 1 min read

I got tired of always going into online formatters or weird terminal commands to view nicely prettified data, so I built Refiner.

Current Features

- Auto-detection: identifies JSON, XML, CSV, Markdown, Code, and plain text automatically

- Interactive tree views: collapsible JSON and XML trees with expand/collapse all

- CSV tables: clean grid layout with alternating row highlighting

- Markdown rendering: headings, lists, blockquotes, code blocks, inline formatting

- Code highlighting: syntax coloring for keywords, strings, numbers, comments

- Three view modes: Raw, Formatted, and Side-by-Side (Cmd+1 / Cmd+2 / Cmd+3)

- Floating panel: always-on-top, follows you across spaces

- Global hotkey: summon with Cmd+Opt+R (customizable)

- Copy formatted output: one-click copy of prettified content

- JSON auto-fix with revert: automatically repairs malformed JSON

My long term goal is that hopefully people will contribute and Refiner can become the most comprehensive way of viewing nicely formatted data locally.

Praise Kier.
