Can supported types (for writing to Excel) be expanded - similar to CSV.write ?

[Lincoln-Hannah]

CSV.write will convert most datatypes to strings, similar to using x -> "$x"

For example it will print Symbols, Enums and Structs.

Could XLSX.writetable be expanded in a similar way ?

I can apply the following to my DataFrame before writing it to Excel, but it would be nice if the package did it.

mapcols( col -> eltype(col)<: Union{String,Number} ? col : (s->  "$s" ).(col),    my_DataFrame  )
