Hi Lucas,

the message there are "no responses an MOP" seem to indicate that you did not define Output Parameters or Responses. They need to be there, which means the Excel Component needs to be connected to the Parameter set.  

Can you send a screenshot of a) the Workbench Project and the b) Parameter Set in Workbench?

In the help you find an example for optiSLang inside Workbench using Excel here: 
Sensitivity Analysis of a Coupled Function in Ansys Workbench
Can you try if this works fine for you?

Best regards,
Markus
