Hi ​@Mandar12,,

Please find the below steps,

In the "Program/File Path" field, enter:
cmd.exe

In the "Parameters" field, enter:
/c taskkill /F /IM excel.exe 
/c tells CMD to execute the command and then close.
taskkill /F /IM excel.exe forcefully closes Excel.

Hello ​@Mandar12 
You wrote parameters in wrong place as in start in path

If you write location as Taskkill
and parameters as /f /im excel.exe it will close the excel file with force.

Hello, Please do find attached screenshot for reference.
