MATLAB: Problem opening excel csv file using xlsread

errorexcelxlsread

I am trying to use the xlsread function to open a part of a CVS excel file that is too large to open in excel (1.07 GB).

B = xlsread('programtest.csv','Sheet 1','A10:F28');

However, I get the following error:

??? Error: The server threw an exception.

Error in ==> xlsread at 250 ExcelWorkbook = Excel.workbooks.Open(file,0,true);

Error in ==> programtest at 5 B = xlsread('programtest.csv','Sheet 1','A10:F28');

Is there a way to solve this issue? Thanks

for CSV file you should use readtable() or csvread().

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;

MATLAB: How to open an existing Excel file and communicate with it using ActiveX

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

The following provides an example of opening an existing Excel file named example.xls and proceeding to write and read with it:

% Specify file name
file = 'D:\Applications\MATLAB701\work\example.xls'; % This must be full path name
% Open Excel Automation server
Excel = actxserver('Excel.Application');
Workbooks = Excel.Workbooks;
% Make Excel visible
Excel.Visible=1;
% Open Excel file
Workbook=Workbooks.Open(file);
% Specify sheet number, data, and range to write to 
sheetnum=1;
data=rand(4);  % use a cell array if you want both numeric and text data
range = 'F10:I13';
% Make the first sheet active
Sheets = Excel.ActiveWorkBook.Sheets;
sheet1 = get(Sheets, 'Item', sheetnum);
invoke(sheet1, 'Activate');
Activesheet = Excel.Activesheet;
% Put MATLAB data into Excel
ActivesheetRange = get(Activesheet,'Range',range);
set(ActivesheetRange, 'Value', data);
% Here you might manipulate the data in Excel
% Now read the data from the sheet; you could specify a new range here
Range = get(Activesheet,'Range',range);
out = Range.value;
% Save file
invoke(Workbook,'Save')
% Close Excel and clean up
invoke(Excel,'Quit');
delete(Excel);
clear Excel;
