Is there something like pywin32 in Julia?
I want to use the stmafm ole/com interface.
PyCall could work, but I am curious if there is a Julia native option.

You can already use `ccall` to natively access the Win32 API in Julia.
This is used extensively in the Julia standard library. See, for example, [how `tempname` is implemented for Windows](https://github.com/JuliaLang/julia/blob/c9805191e32fde9d4aa55e59493178f47444926e/base/file.jl#L498-L543).
Of course, if you are using Win32 APIs extensively, you might want higher-level wrappers on top of the Win32 API. AFAIK there has been no systematic effort to provide this — people usually just `ccall` at need. (One generally tries to keep such code to a minimum in most Julia packages, in order to keep things platform-independent.)

Here is my example to use PyCall to open and modify an existing Excel-file via a COM server:
```julia
# Create COM server via Python Interface
# first: install "pywin32" via conda:
# using Conda; Conda.add("pywin32")
using PyCall
using XLSX
pw = pyimport("win32com")
pwc = pyimport("win32com.client")
FN_excel = raw"C:\tmp\MyTest.xlsx";
if ~isfile(FN_excel)
XLSX.writetable(FN_excel)
end
xlApp = pwc.Dispatch("Excel.Application")
xlApp.Visible = 1
if isfile(FN_excel)
workBook = xlApp.Workbooks.Open(FN_excel)
else
error("file \"" * FN_excel * "\" does not exist!\n")
end
workBook.ActiveSheet.Cells(1, 1).Value = "hello world"
workBook.Close(SaveChanges = 1)
xlApp.Quit()
```
I hope it helps others to get started.
