Hi Rounak,
I understand you are not able to open "Excel" from MATLAB using the function "actxserver".
Please follow the below debugging steps to resolve your issue:
  • In order to determine if the issue is with MATLAB or Excel please start Windows Powershell (click start, type 'powershell' and open Windows Powershell app). In power shell, please type this
>>$excel= New-Object -ComObject excel.application
(If this produces an error then the issue is not due to MATLAB.)
  • Please try the following commands in MATLAB command window to check whether other office applications are working fine:
>>word = actxserver('Word.Application')
>>p = actxserver('PowerPoint.Application')
  • Re-Register the Excel Application: From a command prompt, please navigate to where the Excel.exe file is located and and open Command Prompt in Administrator mode to enter the below command:
>>EXCEL.EXE REGSERVER
I hope the above information helps resolve your issue.
Regards,
Shanmuganathan
