how do i make sharepoint foundation 2010 edit CSV file in excel , as of now when i upload a csv file in sharepoint there is no icon associated with it ,so when i try to click on it it gives me just " save " or "cancel" option but no edit option , my client is a windows 7 box
I think the missing icon and the missing edit button are two different issues.
You can follow the procedures here (just substitute the Excel icon) to get the icon to display: http://www.sharepointsharon.com/2010/03/sharepoint-2010-and-adobe-pdf/
Associating the file extension with Excel may need to be done in your browser: http://social.technet.microsoft.com/Forums/en-US/sharepointgeneral/thread/3ec45ee1-65fc-4049-8fa8-cd9ebb98bd65
If that doesn't work, double-check that CVS is associated with Excel on your desktop.
