Nate's Toolbox
A collection of useful tools that I maintain, and some links to my favorites.
Epochs, other date/time formats, and time zone conversion.
Prototype folder layouts from outlines—ASCII trees before creating real folders.
Generate and detect UUID v1–v8, Nil, Max, and GUID forms — v4 by default.
Repair, validate, and beautify messy or pasted JSON.
Color palettes, format conversion, and a small engine for managing collections over time.
Generate QR codes from presets (Wi‑Fi, contact, URL, and more), export PNG/SVG, and scan codes without opening them.
