I can double-click the file and a browser preview opens that looks like excel.... but it is basically just a browser preview feature and it is read-only.
The file came from a Windows machine.

This response makes a couple of assumptions:
You should be able to use Apache OpenOffice CALC to edit files in the Microsoft Excel file format of .xlsx as per the OpenOffice website:
You may download OpenOffice from this site: http://www.openoffice.org/download/ Alternatively, you can always use the MAC version of Microsoft Office 2011 available for purchase here: http://www.microsoft.com/mac/buy |

If you have opened it in Excel but you are unable to select or change it, the sheet may be protected. If the sheet has been protected using the Tools > Protection > Protect Sheet option then a lock symbol will appear next to the sheet name in Excel 2011. Sheet protection can be removed by using the Tools > Protection > Unprotect Sheet command. |
