MATLAB: Xlswrite1, Object returned error code: 0x800A03EC at line 142

excelxlswrite1

I am first time using xlswrite1 and tried to not use xlswrite in the for loop, I want to enter the data from a structure, which contains 27 fields, each field has Mx1 Data,

I first tried with xlswrite:

      for VariableNum = 1:length(fieldnames(Data))
          xlswrite(FileAddress,Data.(ColumnName{VariableNum}),1,[Column{VariableNum} num2str(4)]);
      end

Although it took me half minute to complete. the above line worked perfectly fine. and then i tried with the xlswrite1, didn't change any input except adding a few lines to open excel,

      Excel = actxserver ('Excel.Application'); 
      File=FileAddress; 
      if ~exist(File,'file') 
      ExcelWorkbook = Excel.workbooks.Add; 
      ExcelWorkbook.SaveAs(File,1); 
      ExcelWorkbook.Close(false); 
      end
      for VariableNum = 1:length(fieldnames(Data))
          xlswrite1(FileAddress,Data.(ColumnName{VariableNum}),1,[Column{VariableNum} num2str(4)]);
      end
      invoke(Excel.ActiveWorkbook,'Save'); 
      Excel.Quit 
      Excel.delete 
      clear Excel

I uses this xlswrite1 in my custom function, which is used in a GUI function. I also changed the second line in xlswrite1 from

Excel=evalin('base','Excel');

Excel=evalin('caller','Excel');

as suggested.

for some reason this gave me error indicated in the title.

Why did you do this to close your workbook:

ExcelWorkbook.Close(false);

I would think that xlswrite1() would expect that Excel has the workbook open. If you don't have an active workbook open, where will it write to? You just have Excel open with no workbook, and no worksheet in the workbook (because the workbook itself is not there). Try getting rid of the .Close call and see if that works.

MATLAB: How to rename a sheet in Excel using the COM interface in MATLAB

You can rename an Excel sheet using the "Name" property of a sheet object. For example the following renames the first sheet of an Excel file:

filename = 'C:\SomeExcelFile.xls';
% Open Excel Automation server
Excel = actxserver('Excel.Application');
% Make Excel visible
Excel.Visible=1;
% Open Excel file
Workbook = Excel.Workbooks.Open(filename);
% Get the list of sheets in the workbook
Sheets = Excel.ActiveWorkbook.Sheets;
% Rename the first sheet
Sheets.Item(1).Name = 'This is sheet 1';

The following code then saves the Workbook, quits Excel and removes the COM server:

% Save the file
Workbook.Save();
% Quit Excel, remove the COM server and delete the related objects
Excel.Quit();
Excel.delete();
clear Excel;
clear Workbook;
clear Sheets;

% Get the Excel version because if it's version 11 (Excel 2003) the file extension should be .xls,
% but if it's 12.0 (Excel 2007) then we'll need to use an extension of .xlsx to avoid nag messages.
excelVersion = str2double(Excel.Version);
if excelVersion < 12
  excelExtension = '.xls';
else
  excelExtension = '.xlsx';
end
% Determine the proper format to save the files in.  It depends on the extension (Excel version).

% Then run the new xlswrite1 function as many times as needed or in a loop 
% (for example xlswrite1(fullFileName, yourArrayName, XL_CellLocation). 
% IMPORTANT NOTE: the Excel object variable MUST exist in the routine that calls xlswrite1()
