HTML component

TREB is just an HTML component, so it fits into standard HTML layouts (like this carousel). Things like the spreadsheet toolbar and the tab bar are optional.

Charts & graphs

Number formats

TREB includes comprehensive number and date formatting with built-in types and custom formats. Decimal separators and groups automatically change to match the browser's locale.

You can try switching the locale to pt-br or en-us.

API & events

TREB has an API and events to connect spreadsheets to your web page or web app. It also includes utilities for formatting and parsing numbers outside of the spreadsheet.

Complex numbers

TREB has built-in support for complex numbers. You can use them like any other value. See the docs for more on complex numbers.
