Could you build this?

Partial Writing a basic macOS Quick Look preview extension is straightforward, but robustly parsing, rendering, and syntax-highlighting 300+ disparate and complex file formats (e.g., SQLite schemas, archives) inside strict system sandbox constraints requires substantial native systems development.

What it would actually take: The app is implemented in Swift/Objective-C using macOS QuickLook Extension APIs (QLPreviewProvider). The challenge lies in bundling safe, performant zero-dependency parsers for hundreds of formats (e.g., SQLite C-libraries, libarchive for ZIP/tar/rar, syntax highlighters) that execute within tight sandbox memory and CPU watchdog limits without crashing Finder.
