Hi

If u mean to say that how we can upload the test cases from excel sheet to TD.

For this purpose, we need install an ADD-IN called Microsoft Excel Add-In.Once the Test cases are created in the Excel Sheet, u can directly upload the test cases into the TD/QC from Excel sheet by selecting "IMPORT To Test Director" from Tools Tab.

After giving all the correct details for the asked questions, we can find the test cases saved in the Test Plan Tab.

and then from there u can move the test cases to Test Lab for executing.

let me know if I were wrong :)
