Extensions
The `excel` extension, unlike what its name may suggest, does not provide support for reading Excel files.
Instead, provides a function that wraps the number formatting functionality of the [i18npool library](https://www.openoffice.org/l10n/i18n_framework/index.html), which formats numbers per Excel's formatting rules.  
Excel files can be currently handled through the [`spatial` extension](#docs:extensions:spatial:overview): see the [Excel Import](#docs:guides:file_formats:excel_import) and [Excel Export](#docs:guides:file_formats:excel_export) pages for instructions.
