When i import product through excel, the products at back end but not visible at front end, the thing is, when i save the product manually then only the product display at front end. How can i manually save all products, it's waste my time.
As in your case, Products visible in frontend only when manually save the product, you can save all the products once,by Catalog > Manage Products , select Actions under updtate attributes & than select Catalog, Search under Visibility & save it. link : here
