Hello, I personally believe that such a package would be too much heterogeneous, and that collection of thematic packages would be better.
That’s said, I am keeping this function in my personal (intentionally unregistered) package of “everything” to do with data: GitHub - sylvaticus/LAJuliaUtils.jl: Utility functions for Julia, mainly dataframes operations (I stil need to upgrade it to DataFrames 0.11.3/Missings.jl).
You may be interested also in OdsIO.jl for import/export with OpenOffice/LibreOffice format.
