I wrote this code to connect to a database and retrieve 9 columns my columns will have this values AgentID = 1234 Question1 = strongly agree Question2 = agree Question3 = strongly disagree Question4 = etc Question5 =etc Question6 =etc Question7 =etc Question8 = etc

I need to change the value of the questions from string to numeric

Strongly Agree – 5 Agree – 4 Neutral – 3 Disagree – 2 Strongly Disagree -1

then write it back to the excel file

    update: as poj pointed out, not all the values in the row are an "answer", so you'll have to see if each value is a key in the hash.

    Use a hash: 

    my %scores = (
    'Strongly Disagree', => 1,
    'Disagree', => 2,
    'Neutral' => 3,
    'Agree' => 4,
    'Strongly Agree' => 5
); 

while ( $row = $sth->fetchrow_arrayref ) {

    $sheet->write_string($i, $_, $scores{ $row->[$_] } || $row->[$_], 
+$default_format) for (0..$#$row);
    $i++;
}

      My answer looks like this now

    • B937 5 5 5 5 5 5 5 5

      B631 5 5 5 3 4 5 5 5

      • can I add an extra field to the right that will add the answers and get the average like for my second value will be like this , 5+5+5+3+4+5+5+5/8 Also can I add extra row at the end to get the total of the column value and divide by the number of the values like 5+5/2

        I should think you can do both of these things. Give it a try!

        ( You probably want to declare a counter outside the loop for the grand total, and another counter within the loop to sum the fields and make a row total, which you would print out and also add to the grand total counter ...)
