I have an Array{String,1} which I want to convert into an array of data types to use with loadnsparse in JuliaDB. There appears to be no way to convert a string such as “Union{Missing, Int64}” into the obvious type?

Meta.eval(Meta.parse(“Float64”)) This gives me a result that is a data type. The Meta package appears to be built in and doesn’t need to be added.

Convert string of type/eltype to Type itself

So what do you do when the data is too large and sparse to have its types detected? I have 2000+ columns to load here.
