My question is very simple.

I have a h5 file with the following structure.

```julia
Dict{String,Any}("mb" => MeansBands
  class: obs
  product: forecast
  cond: none
  para: full
  dates: 2021-03-31 - 2030-12-31
  # of variables: 10
  bands: ["50.0%", "60.0%", "90.0%"]
)

```

Would you mind letting me know how to convert this h5 to csv?

Hi!  
You can use the package [GitHub - JuliaIO/HDF5.jl: Save and load data in the HDF5 file format from Julia](https://github.com/JuliaIO/HDF5.jl) to read it and then the `writedlm` function from the standard library `DelimitedFiles`.
