I would like to read a tab delimited text file created in Excel into

It prints:
Can't use string ("") as an ARRAY ref while "strict refs" in use at

You just need a pair of "[" ... "]" around "split /\t/", that's all:
push @arr, [ split /\t/ ];

(for reference --> see perldoc perldsc)

}

print $arr[$i][$j];
