I was trying to convert a comma separated list of strings into a normal array. So B0005.cycle is a struct with some fields:
B0005.cycle.type is a comma separated list:
I tried to convert it into an array by doing this: [B0005.cycle.type] but it gives this output:
However I want ["charge", "discharge","charge","discharge",...]. So how do I go about this?
I have attached the mat file below.

I can see that you are trying to convert a comma separated list of strings to normal array. You can do it like following.
arr={B0005.cycle.type};
newarr=[];
for x=arr
newarr=[newarr; string(x{1})];
end
Refer to the following documentation to know more about comma-separated lists in MATLAB.

This can also be done in one line (using type for an example):
If you want a horizontal array:
typearr = string({B0005.cycle.type});
If you want a vertical array:
typearr = string({B0005.cycle.type}');
{} will convert the comma separated list of char to cell array of char
' will transpose the cell array
string will convert cell arrays of char to arrays of string
