Nope - not going there. Attach it here with the paperclip icon. If it's too big (> 5 MB), crop off some values. If the file extension is not accepted, zip it up and post the zip file.

Error using dlmread (line 147)
Mismatch between file and format character vector.
Trouble reading 'Numeric' field from file (row number 1, field number 1) ==> Text,Class\n
Error in csvread (line 48)
m=dlmread(filename, ',', r, c);

csvread expects all columns to be numbers so it failed because the first column is text. But as you can see from @Stephen23's answer, it works and there is no double quote symbol in the cells. So we are not able to reproduce your problem.

@mahmood aljamal note that the single apostrophes are not really part of the character array:
>> charArray = T.Text{1}
charArray =
'Subject: christmas tree farm pictures '
>> charArray(1)
ans =
'S'
See, the first element is an S, not a single apostrophe.
