Hi..., Currently i am trying to read an excel files with two different ending . dvd & .sod (From SCADA system). i am using the [Values] = xlsread(File_to_Open) to do so. my question is: In the excel file i have the values so written (Example: 21,1) with comma not point (I am using a German Windows system) and when i am importing those data to matlab i am getting something like 37, I am not sure why!! Can you help me with this problem of importing when using the xlsread() function?

I've enabled the decimal dot on my German system to avoid such troubles.

在 MATLAB Online 中打开

I don't recognize these extensions. I assume they are text.

Here are two files, which replace comma by dot. Pick one. Please, make copies of your files before you try these functions.

    function fread_( strInFileSpec, strOutFileSpec )
        fid = fopen( strInFileSpec, 'r' );  
        str = fread( fid, inf, '*char' );  
        fclose( fid );
        str = strrep( str', '.', ',' );
        fid = fopen( strOutFileSpec, 'w' );
        fwrite( fid, str, 'char' );
        fclose( fid );
    end 
    function memmap_( strInFileSpec )
        file    = memmapfile( strInFileSpec, 'writable', true );
        comma   = uint8(',');
        point   = uint8('.');
        file.Data(( file.Data==comma)' ) = point;
    ... delete(file)
    end

Neither .dvd nor .sod is included in this list: File formats that are supported in Excel

Thx for the help this type of Format is generated by ENERCON SCADA system. I am actually becoming no problems using Excel to open those files. my final soluation was to use the third output of the xlsread() function which gives the opend file as Cell array (without any changes) and then re-change it to numbers for example by using cell2mat. thx again for ur help
