Unfortunately if your intention is to just CTRL+C and CTRL+V, it won't work. As other answers have clearly elaborated, you will need to find and install a 3rd party software that is capable of doing this. Alternatively, you can also find websites that will convert the documents. You will just need to upload the file onto said site. Considering these are short stories you wish to compile, I assume it shouldn't be a problem. I'd be wary of uploading any sensitive information. A quick Google search should help you with the software/website you need.
If you can't find it, you could also try this.
