The Confluence wiki has an Office Excel macro that enables you to attach a spreadsheet to a wiki page and then show a specified worksheet and region of the Excel file on the page. To do this:
- add a page to your wiki using the Add menu
- save the page
- add an attachment to that page via the Add menu
- click the Insert/Edit Macro icon in the toolbar
- You'll see a dialog box come up. Select the spreadsheet you attached from the File Name popup menu
- Optionally, if you'd like to show a specific worksheet or row/column range, specify those values in the provided fields
- Click Insert and then save your page
