I have noticed that wrapping multiple JSON objects in [ ] with a comma separator causes this to parse correctly:

julia> s = "[{\"name\":\"Marco\"}, {\"name\":\"Julia\"}]"
"[{\"name\":\"Marco\"}, {\"name\":\"Julia\"}]"

julia> JSON.parse(s)
2-element Vector{Any}:
 Dict{String, Any}("name" => "Marco")
 Dict{String, Any}("name" => "Julia")

This still leaves the problem of converting a non-delimited multiple-object JSON string to a comma separated one that can be wrapped in brackets.

from json.jl.

Sorry, one more thing. It works if you repeatedly read from a stream:

julia> s = "{\"name\":\"Marco\"} {\"name\":\"Julia\"}"
"{\"name\":\"Marco\"} {\"name\":\"Julia\"}"

julia> stream = IOBuffer(s)
IOBuffer(data=UInt8[...], readable=true, writable=false, seekable=true, append=false, size=33, maxsize=Inf, ptr=1, mark=-1)

julia> JSON.parse(stream)
Dict{String, Any} with 1 entry:
  "name" => "Marco"

julia> JSON.parse(stream)
Dict{String, Any} with 1 entry:
  "name" => "Julia"
