Convert pasted Excel/Spreadsheet data to 2d array in JavaScript

table-to-array.js

// Converts a (user-pasted) string to a 2d array, utilizing line breaks and tabs.
function interpret_table( data ) {
  
    var table = data.split("\n");
    
    for (i in table) {
        table[i] = table[i].split("\t");
    }
    
    return table;
}

Looks basic, but it's quite useful. See this fiddle for usage:
