I developed one VSTO Excel Add-in, To meet workflow requirement we need to replace active worksheet (it's whole content) with another excel file's worksheet.
We are planning to add one button in Excel Add-in where end user can choose another excel file which are located in their hard drive. Active worksheet will be replace with selected excel file's first worksheet.
I am stuck to copy worksheet from another excel file.
I am bit new in VSTO add-in, Can you please help me in correct direction.
