I am trying for a while to pull data for around 160 metrics for the last imported date and previous one so I can automate some stuff.
This is how my datatable looks
If you are sure that you only return numbers or empty cells, this would prevent a double lookup:
=IFERROR(VALUE(A1&" "),"")
In your case, substitute A1 with VLOOKUP($C$3,Table1[#All],2, FALSE)
A1
VLOOKUP($C$3,Table1[#All],2, FALSE)
