массив, чтобы преуспеть в phpexcel

Я пытаюсь преобразовать массив в Excel, используя phpexcel. Итак, мой формат массива

Array
(
[0] => Array
(
[0] =>
[1] => Box Name
[2] => X1
[3] => X2
[4] => Y1
[5] => Y2
[6] => Patiend_ID
[7] => Age
[8] => Gender
[9] => X-Axis
[10] => X-Value
[11] => Y-Axis
[12] => Y-Value
)

[1] =>
[2] => Array
(
[0] => HM
[1] => 3.3
[2] => 6.6
[3] => 7.9
[4] => 10
[5] => 22
[6] => 63
[7] => MALE
[8] => Medication Adherence
[9] => 6
[10] => Caloric output
[11] => 10
)

[3] => Array
(
[0] => ML
[1] => 0
[2] => 3.3
[3] => 4.0
[4] => 7.9
[5] => 27
[6] => 56
[7] => FEMALE
[8] => Medication Adherence
[9] => 0
[10] => Caloric output
[11] => 5
)

[4] => Array
(
[0] => LH
[1] => 6.6
[2] => 10
[3] => 0
[4] => 4.0
[5] => 33
[6] => 58
[7] => MALE
[8] => Medication Adherence
[9] => 8
[10] => Caloric output
[11] => 0
)

[5] => Array
(
[0] => LL
[1] => 0
[2] => 3.3
[3] => 0
[4] => 4.0
[5] => 48
[6] => 62
[7] => FEMALE
[8] => Medication Adherence
[9] => 1
[10] => Caloric output
[11] => 3
)
)

код, который я пробовал

Таким образом, это дает ошибку, как и неверный аргумент. Что я делаю не так. Я посылаю массив из JavaScript в php с помощью вызова AJAX. Любая помощь будет оценена.
