I have a spreadsheet I am trying to import with readtable(). Mostly, the import works perfectly. However, there is a single column of data that has both numeric values and strings in it. Matlab reads the numeric values but recodes the strings as 'NaN'.

So for example, in the Excel spreadsheet I have a column "Response = {5, 10, cat, 12}". However, Matlab reads this as "Response = [5 10 NaN 12]".

I would like Matlab to read it as a cell array with the values as they are in the .xlsx spreadsheet.

I suspect this is possible with spreadsheetImportOptions, but I'm not sure how.

Thanks!

file = 'rating_task_raw_21_02_17.xlsx';
Data.Task_Raw = readtable(file);

In this instance, MATLAB has selected a numeric data type for the column. You can use the optoins to change the data type used to meet your needs. In this instance, I would probably use categorical, but char or string should work, too.
