xlswrite inserting characters to excel formula help

I have a simple code

clear all; close all; clc;
input(1,1) = {'=QFS("DIS","net_income","TTM")'};
xlswrite('test.xls',input)

however, the output of the spreadsheet

is there reason why the xlswrite inserts an @ character to the output? is there a way to remove it during the write so I dont have to manually edit?

the QFS function is a custom installed excel function.

I think the issue is that QFS is not a recognized Excel formula, so Excel is assuming you are using a named table reference (I think that's what it's called). The main point - if you replace QFS with the name of a recognized Excel formula, there is no '@'. If you use something that is not a formula or cell reference, the '@' is inserted before it.

ok thanks. Just wanted to see what the reason is and if there are parameters within xlswrite can prevent this from occurring
