I suspect that I can actually read the log file data directly into Matlab without conversion. It is just a comma separated variable format(.csv), I believe, and I think it should be accessible to some Matlab input routine.
However,I dont not know the matlab input routine; It would be very helpful if someone can enlighten me on the input routine
thanks in advance, Cordelle

This is not enough information to give a more explicit answer than:
  • Import the file by e.g. importdata or fopen / fscanf.
  • Export the data by xlswrite.
I suggest to add mire details, e.g. the file's contents by editing the original question (not as comment or answer).

When I imported the file using importdata this occured:
data: 3
textdata: {863x4 cell}
what does this mean? and how can I convert the imported file into an excel file?
That means that data is a structure containg the field "textdata", and that "textdata" contains a cell array (each element of a cell array can be a different type of number, string, or even another array).
Try:
xlswrite('myxl.xls',data.textdata)
winopen('myxl.xls')

That means its a cell in a structure.
You can access data from structures:
and use
If you need editing in between you should do that.
If you are unfamiliar with cell and structures at all in MATLAB, I point you to

Error using load
Number of columns on line 3 of ASCII file
\\dc1nas\Projects-AB\AS\Jobs\Jobs-2012\1538_KSAT_SG24\40_Testin\03_Test_Report\SAT\SAT_Demo_Passes\passReport.TERRA_2013_107_165606
must be the same as previous lines.
How can i correct this issue? (I used the "Load" input routine)

Please do not post explanations like "I used the "Load" input routine", but the corresponding code. This will reduce misunderstandings. Thanks.

clear; clear all; fileip='filename.csv'; g=char(fileip); g=g(1:end-4) fileop=horzcat(g,'.xlsx') g=fileip(1:end-4); [~,~,F]=xlsread(fileip); F=cellstr(F); %delete the header rows (4 rows) F([1:4],:)=[]; for a=1:size(F,1); b=F(a,1); c=char(b); D(a,:)=strsplit(c,','); end xlswrite(fileop,D); disp(['--------------Process complete---------------------']);

There's a {}Format button to format code as such. That would make your post more readable.
g = char(fileip);
is a no-op. fileip is already char. In any case,
[path, basename] = fileparts(fileip);
fileop = fullfile(path, [basename, '.xlsx']);
would be a lot simple and safer.
F = cellstr(F);
is also a no-op. F is already a cell array. Same for
c = char(b); %b is already char.
In any case, the code is not going to work. It only writes the first column of the csv file. (hint: xlsread already does the splitting at the comma)
