Cannot index Cells

[4zv4l]

Hi !

I basically copy-pasted the example from the Readme and just changed the sheet name. It seems that I cannot index any cells, I tried multiple way but none worked. For this issue I will simply stick to the one showed in the readme.

#!/usr/bin/env raku

use Spreadsheet::XLSX;

my $workbook = Spreadsheet::XLSX.load('sheet.xlsx');

say "Workbook has {$workbook.worksheets.elems} sheets";

# Doesnt work for me, I need to add worksheets[0] (or any index)
# No such method 'name' for invocant of type 'List'.
say $workbook.worksheets[0].name;

my $cells = $workbook.worksheets[0].cells;
say .value with $cells[0;0];      # A1
say .value with $cells[0;1];      # B1
say .value with $cells[1;0];      # A2
say .value with $cells[1;1];      # B2

result
