Problem: I have a excel ile written by others. I need to run the VBA macro from withng Matlab.

I am not certain the macro name is correct. It is the name in the VBA editor. It is a botton click command macro in the spread sheet.

runFile = [filelist(i).folder,'\',filelist(i).name] ;

% Create object.

ExcelApp = actxserver('Excel.Application');

% Show window (optional).

ExcelApp.Visible = 1;

% Open file located in the current folder.

ExcelApp.Workbooks.Open(fullfile(runFile));

workbook = ExcelApp.Workbooks.Open(fullfile(runFile));

% Run Macro, defined in the module "Module1" with no parameters and a return value.

ExcelApp.Run('btnAnalysis');

>>> When running

Error using COM.Excel_Application/Run

Invoke Error, Dispatch Exception:

Description: Cannot run the macro 'btnAnalysis'. The macro may not be available in this workbook or all macros may be disabled.
