Currently, if you use the Office Excel macro to embed a sheet on a Confluence page, the file will be embed according to the page width.That said, in case the spreadsheet is larger than the page width, instead of adjusting zoom or providing a horizontal scrollbar, the macro will split/cut the content in two pages, which is not ideal when visualising large tables or graphics.

Suggested resolution

Provide the ability to set the document width/zoom, or which columns that should be displayed. Or, add a horizontal scrollbar in the bottom of the macro, so users can scroll the document, providing a better experience.
