For a long time I have been getting an array of values from a spreadsheet using.

\@cell_array = $worksheet->range($excel_data_range)->{'value'};
[download]

and then going through the 2 dimensional array to read the value of each cell.
I now want to read tags and formulae that associated with each cell.
I guess that I need something instead of ‘value’ in the ->{} .
Can anyone tell me what this should be or even a location where all the options for range can be found.
