Empty value in excel is converted into 0

[sc-brikis]

Every empty value in excel is converted to 0 due to fact that:

isNaN('') => false

and line 41: _data[k.trim()] = isNaN(value) ? value : +value

makes empty record to 0.

I suggest following to check if value is number or not:

(isNaN(value) || value === '') ? value : +value;

you can find working sample here.

Is there a solution for this?
