I'm trying to open an existing Excel file, add data, then save the file. I've tried several different variations on saving the file, but I'm not having any luck. Code chunk:
%% Open Existing File & Activate / Re-name Sheet 3 hExcel = actxserver('Excel.Application'); hWorkbook = hExcel.Workbooks; invoke(hWorkbook,'Open',filename_ext); %% filename_ext -- existing file Sheets = hExcel.ActiveWorkBook.Sheets; hSheet = get(Sheets,'item',3); hSheet.Activate; hSheet.Name = 'CYCLE';
%% Add Data & Formatting %% <etc>
%% Save File & Close % hWorkbook.SaveAs(filename_ext); %% V1 % hWorkbook.Saved = 1; % hWorkbook.Save %% V2 % invoke(hWorkbook,'Save',filename_ext); %% V3
hWorkbook.Close hExcel.Quit hExcel.delete
The differet save methods above give a variety of different error outputs.
* hWorkbook.SaveAs(filename_ext); Cannot find an exact (case-sensitive) match for 'SaveAs'
The closest match is: saveas in C:\Program Files\MATLAB\R2012a\toolbox\matlab\general\saveas.m
* hWorkbook.Save No appropriate method, property, or field Save for class Interface.000208DB_0000_0000_C000_000000000046. * invoke(hWorkbook,'Save',filename_ext); Error using Interface.000208D8_0000_0000_C000_000000000046/invoke Invoke Error: Unknown name or named argument
In another code section I've used the above SaveAs format (when I'm creating a new file--not adding data to an existing file)without issue, so I'm uncertain on how to correct the issue.
Any help would be appreciated.
hWorkbook = hExcel.Workbooks is collection of all the workbooks that you have open. To save one, you need the handle to one particular single workbook. Try using hWorkbook = hExcel.ActiveWorkbook instead. This will get the handle to just one workbook - the currently active one - instead of the whole collection of them. I know you may have only one open, but it's the hierarchy that's important. It's not going to automatically make hExcel.Workbooks equal to hExcel.ActiveWorkbook just because you have only one open.
Does this give any errors or warnings?
%open Excel e = actxserver('Excel.Application');
% Workbook eWorkbook = e.Workbooks.Add;
% Make the first sheet active eSheets = e.ActiveWorkbook.Sheets; eSheet1 = eSheets.get('Item', 1);
%test data Range = eSheet1.get('Range','A1:A1'); Range.Value='TEST';
% Save the workbook eWorkbook.SaveAs(FileName);
%open: e.Visible = 1;
