Convert ASM to OBJ

QUICK ANSWER
Is it possible to convert ASM to OBJ?
Yes - ASM converts to OBJ.

The real 'conversion': assemble the source into an object file with NASM or MASM (nasm -f win64 file.asm -o file.obj). The .obj is then linked into an executable. This is compilation, not a document conversion.
