As part of your research, you may find that you want to export the reference list of a document you're reading into EndNote. Or, you may have a hand-written reference list you created yourself that you'd like to convert into EndNote references.
Traditionally this was difficult, because you could not upload a Word document into EndNote and have it make a list of references. But now there is a free web app called Citation Finder Vercel that will attempt to convert your text references into .RIS. All you need do is paste the text of your references into the app and it will do the rest.
The quality of the results will vary depending on the format of the reference list and the referenceing style it has been created in.
