The 
               		Silk Central integration with Microsoft Excel provides two options to modify your tests in Excel. 
               	 
            
 
            	 
             
               		
               - Export and update: This option allows you to export manual tests from 
                  		  Silk Central to Excel, to update the tests in Excel, and to re-import the changed tests into 
                  		  Silk Central. 
                  		
               
- Import: This options allows you to create manual tests and business-process tests in Excel and to import these tests into 
                  		  Silk Central. 
                  		
               
In both scenarios, you have to create a mapping file to synchronize the columns between Excel and 
               		Silk Central. 
               	 
            
 
            	 
            Note: When importing or updating tests from or when exporting tests to Excel, 
               		Silk Central supports only 
               		.xslx files.
