i was to read a coloumn from xlsx file which is simple to implement as following

columnB = xlsread(myExample.xlsx,'B:B'); % this works

but i m designing a app in appdesigner, i want to give option to user to input desired column name, i tryed this through

% lets suppose my text edit field is named as app.Columneditfield

columnB = xlsread(myExample.xlsx,'app.Columneditfield.Value:app.Columneditfield.Value');

% this gives error not a valid range

% because when '' is used to define range it does not pick >>app.Columneditfield.Value<<

% kindly guide

Assuming app.Columneditfield.Value is already a char, you can simply create the range like this:

Range=[app.Columneditfield.Value ':' app.Columneditfield.Value];
columnB = xlsread('myExample.xlsx',Range);

You forgot to leave in the spaces:

%You wrote:
Range = [app.ColumnEditField.Value':'app.ColumnEditField.Value];
%You should have written:
Range = [app.ColumnEditField.Value ':' app.ColumnEditField.Value];
