How to remove all weird column names from a table and replace them (with numbers or alphabet letters)?

I have a file in the .csv format.

When I transfer it to Matlab, the column names turn into some kind of gibberish.

In fact, I need to remove all these names and replace them with anything (numbers or letters of the alphabet in ascending order).

The problem is, how to remove all the column names at once without manually entering them in the removevars command?

T = readtable(myfile) ; 
T.Properties.VariableNames = {'1','2','3','4','5','6','7','8'} ; 

NOTE: The column names on the right should be of same size of number of columns.

Also give a try on:

T = readtable(myfile,'VariableNamingRule','preserve')

The second option didn't work as expected.

But with the help of your first option (and my addition) it worked.

T = readtable(myfile.csv);
number_of_column = string(1:size(T,2));
T.Properties.VariableNames = number_of_column;
