I have a textfile and I imported data using importdata() command in matlab

I have tried Delimiter with space ' ' and '\t'

All data is saved in a struct as fine I as need but the problem is in the first line all of it is saved in one cell like date time machine power energy heat

All of the other data like ? , MW , KJ and 45 are save in separate cells which are fine.

I want data from the first row as separate entities like data time machine etc

If I save that cell in a variable name X then output is like 'date time machine power energy heat'

When I check class of this its char

What I want know is to convert this char to a string so that I can continue writing code for my GUI

String == Character array in MATLAB, (but you also have cell arrays of strings). — Stewie Griffin

You can probably design a class names string and use that one, but I would not recommend it to anyone who actually want his code to work well (someone may have done it since he thought it prettier , but this person have likely paid the price in blood). Matlab have a lot of functions which deals with "cell arrays of strings". And writing a custom string clase would not only be slow, but also force you to rewrite all functions handling strings as char arrays (and also "cell array of strings"). — patrik

Cell Array are much better for handling Strings and it is more memory efficient than multiple Char Arrays. — GameOfThrows

What should I do to save date time and machine etc to store in separate variables — Ayesha Zernab

Answering after your comment

d = X{1}

Take any variable like Z use textscan to get your desired result

Z = textscan(d , '%s');

This will make Z a cell of order (1 X 1)
Z{1}(1) will be date
Z{1}(2) will be time
Z{1}(3) will be machine
......
