I have two lists, 

data = {{1000,800}, {1500,3300}}

and 

data1 = {{0,0}, {1,0}}

I combined them and exporter them:

Export["...path", {data, data1}, "List"]

In a different file, I import it:

datar = Import["...path", "List"]

Of which d1 = datar[[1]] seems to be a list, but when I plot 

ListPlot[d1]

it says that it's not " a list of numbers or pairs of numbers.

use CSV and To Expression to convert to numeric format

data = {{1000, 800}, {1500, 3300}}
data1 = {{0, 0}, {1, 0}}
Export["jose", {data, data1}, "CSV"]
datar = Import["jose", "CSV"]
d1 = ToExpression[datar[[1]]]
ListPlot[d1]
