Hello I have excel file that contains the things that I need and things that I don't.
text1.xls
Jshgfy Kashs Klaksh Item Khabsd Hsgbana Quantity
1 2 4 1 4 4 1
1 3 4 24 4 2 3
2 2 3 2 1 1 1
Things that I need are the item and quantity column. This is what I tried.
fh = xlswrite('texxt.xls'); % created a new file
[num text raw] = xlsread ['text1.xls];
I took raw and did strcmp(raw, item) to find the position of item on the xls file but I got an error. How do I find the position of item and quantity and extract the whole column and put in the new file?
Thank you.

xlsread['text1.xls]; rather than xlsread('text1.xls'); is that a typing mistake? Use copy&paste!
What exactly did you try and what error message did you get?

I did write xlsread('text1.xls'); after typing this I got num text and raw. After this I tried
t = {'item'}
strfind(raw, t)
to find if the first row had item. It gave me an error saying
Error using cell/strfind(line32)
if any of the input argument are cell array, the first must be a cell array of strings and the second must be a character of array.

Do you not know in advance what column number 'item' may be in? Use ismember() to find the column number if you can't use a known, predetermined column number.

Try this:
ca = {'Jshgfy', 'Kashs', 'Klaksh', 'Item', 'Khabsd', 'Hsgbana', 'Quantity'}
[ia, ib] = ismember(ca, {'Item'})
letter = find(ia) + 'A' - 1
cellReference = sprintf('%c:%c', letter, letter)
