I have saved some data in Julia without any thought for formatting it. The saved file look something like the following;

```julia
([0.123, 0.124, ... ,0.999], [0.222, 0.223, ..., 0.999])

```

Can someone tell me how to parse the text file as tuple in Julia?

It’s bad practice in general, but for a once-off to fix a mistake you could do:

```julia
str = readchomp(filename)
t = eval(Meta.parse(str))

```

I’d recommend just using JLD2.jl.  
You can just do:

```julia-repl
julia> data = rand(10,10);

julia> JLD2.jldsave("data.jld2"; data=data)

julia> JLD2.load("data.jld2")
Dict{String, Any} with 1 entry:
  "data" => [0.636269 0.0650003 … 0.758512 0.482105; 0.385604 0.769785 … 0.3141…

julia> data2 = JLD2.load("data.jld2")["data"]; data == data2
true

```
