Convert 10000-element Vector{BitVector} into a matrix of 1 and 0 and save it in Julia-CodePudding

I have a "10000-element Vector{BitVector}", each of those vector has a fixed length of 100 and I just want to save it into a csv file of 0 and 1 that is all. When I type my variable I almost see the kind of output I want in my csv file.

Amongst the many things I have tried, the closest to success was:

CSV.write("\\Folder\\file.csv", Tables.table(variable), writeheader=false)

But my csv file has a 10000 rows and 1 column where each row is something like Bool[0,1,0,0,1,1,0,1,0].

This is not the most efficient option, but I hope it should be good enough for you and it is relatively simple and does not require any packages:

open("out.csv", "w") do io
    foreach(v -> println(io, join(Int8.(v), ',')), variable)
end

(the Int8 part is needed to make sure 1 and 0 are printed and not true and false)

X = [[1,0], [0, 1], [1, 1]]
hcat(X...)
