A macOS app that auto-detects and renders JSON, XML, CSV, Markdown, code, and more.
Or in other words, an app for data refinement.
You deal with messy text constantly: minified JSON from an API response, raw XML payloads, CSVs from a database export, Markdown you want to make quick edits to. Instead of hunting for an online formatter, pasting into some random website, or writing a quick script, just hit a hotkey. Refiner detects the format automatically and shows you a clean, syntax-highlighted, interactive view instantly.
The long-term goal is to prettify any text format. Contributions for new format renderers are very welcome.
- 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, with one-click revert to the original
