I'm trying to read in a .txt file and convert the contents to an array. The text file is always formatted as follows (with additional items always on new lines):
Array = {
'Item1', 2526976, 8, 14, 11, [224,224,137,80];
'Item2', 2526976, 8, 18, 15, [224,224,137,80];
};
What is the sytax I use to use with textscan so that it loads into the workspace as follows:

If the file is formatted using MATLAB syntax, rather than trying to read it as data I'd consider renaming it to have the extension .m instead of the extension .txt. If you do that you could run it as a MATLAB script file.

Try something like this —
Array = {'Item1', 2526976, 8, 14, 11, [224,224,137,80]
'Item2', 2526976, 8, 18, 15, [224,224,137,80]};
fido = fopen('Test.txt','wt')
for k = 1:size(Array,1)
fprintf(fido, '%s, %d, %d, %d, %d, [%d,%d,%d,%d]\n',Array{k,:});
end
fclose(fido);
type('Test.txt')
fidi = fopen('Test.txt','rt');
C = textscan(fidi, '%s %d %d %d %d [%d %d %d %d]', 'Delimiter',{','}, 'CollectOutput',1)
fclose(fidi);
C
C{1}
C{2}
.

This is as close as I can get to that —
Array = {'Item1', 2526976, 8, 14, 11, [224,224,137,80]
'Item2', 2526976, 8, 18, 15, [224,224,137,80]};
fido = fopen('Test.txt','wt');
for k = 1:size(Array,1)
fprintf(fido, '%s, %d, %d, %d, %d, [%d,%d,%d,%d]\n',Array{k,:});
end
fclose(fido);
type('Test.txt')
fidi = fopen('Test.txt','rt');
C = textscan(fidi, '%s %d %d %d %d [%d %d %d %d]', 'Delimiter',{','}, 'CollectOutput',1)
fclose(fidi);
C
C{1}
C{2}
T1 = array2table(cell2mat({C{2}(:,1:4)}));
T1 = [addvars(T1,C{1}, 'Before',1) table(cell2mat({C{2}(:,5:8)}),'VariableNames',{'Var5'})]
.
