Getting Started
Install, first launch, the basics.Using Numlex
How the sheet language works.- Natural calculations Arithmetic, percentages, dates, sections and totals — plain lines that are checked live.
- Variables & functions Assign values with name = expression, reuse them anywhere, and call the built-in math functions.
- Units, currencies & weather Convert about 290 units, 166 live fiat currencies, and look up the weather for a city you type.
- Linked answers Turn any answer into a live token that other lines can reuse — change the source, everything follows.
- Sheets & files Named sheets, one-level folders, local storage, and .nlx import/export.
Reference
Formats, styling, constants, privacy.- Number formats Regional presets, thousands separators, compact notation, and decimal-comma handling.
- Styling & constants Appearance settings across five tabs, and up to 100 app-wide constants available in every sheet.
- Privacy & network Local-first by design: what stays on your Mac, and the only two requests Numlex ever makes.
