Just place it.
You can paste data from an Excel spreadsheet into an InDesign or document. The Clipboard Handling preference settings determine how text pasted from another application is formatted.
If Text Only is selected, the information appears as unformatted tabbed text, which you can then convert to a table.
If All Information is selected, the pasted text appears in a formatted table.
If you want more control over formatting the imported table, or if you want to maintain spreadsheet formatting, use the Place command to import the table. If you want to maintain a link to the spreadsheet, select the Create Links When Placing Text And Spreadsheet Files option in File Handling preference settings.
Hope this helps.
