I am importing data from an excel spreadsheet as follows:
options = readtable('options.xlsx');
Some of the excel cells contain descitions of arrays like "[1,2,3]". The cell from readtable would then be:
{'[1,2,3]'}
I would like to convert this to an array of doubles like
[1,2,3]
How can I go about doing this?

It gets tricky with different variable types and widths, but hopefully this helps. Worst case, you build up the new table element by element:
% build example like your table
t=table();
t{1,1}={'[1,2,3]'};
t{1,2}={'[4,5,6,7]'}
t =
1×2 table
Var1 Var2
___________ ___________
{'[1,2,3]'} {'[4,5,6,7]'}
% start a new table
t2=table();
% convert the text in the cell to an array:
t2{1,1}=str2num(t{1,1}{1});
t2{1,2}=str2num(t{1,2}{1})
t2 =
1×2 table
Var1 Var2
___________ ________________
1 2 3 4 5 6 7
