{"c2array":true,"size":[10,1,1],"data":[[[0]],[[0]],[[0]],[[0]],[[0]],[[0]],[[0]],[[0]],[[0]],[[0]]]}[/code:dcdlqzs8]
This is the result of a "AsJson" from an empty array.

edit: If it can be of help, this is how your example data should look like :
[code:dcdlqzs8]{"c2array":true,"size":[10,3,1],"data":[
[[1],["Jeffrey"],[5]],
[[2],["Lisa"],[72]],
[[3],["Pamela"],[31]],
[[4],["Anna"],[67]],
[[5],["Antonio"],[28]],
[[6],["Judith"],[45]],
[[7],["Billy"],[88]],
[[8],["Amy"],[76]],
[[9],["Theresa"],[69]],
[[10],["Kathryn"],[25]]
