Hi, Hari, and Welcome to The Cove!
In our wiki we try to display all info in the wiki's format. If your wiki has a WYSIWIG editor, it should be possible to copy-paste the table into the wiki's editor. But the formulas do not copy-paste.
If you must have formulas in your controlled spreadsheets, then you will need to upload the Excel file itself to the wiki. We'd recommend that you do this in addition to (and not instead of) displaying the info as a wiki-table or as an image.
You might also look into a wiki that can display office documents natively. Atlassian's Confluence
can do that.
