Using RefWorks with Overleaf
Export your bibliography from RefWorks in .bib format to use in Overleaf.
Save this exported file to a location which allows direct linking (e.g. google drive), to keep it in sync when you add new references.
BibTeX is a file format used for lists of references for LaTeX documents. Many citation management tools support the ability to export and import lists of references in .bib format. Some reference management tools can generate BibTeX files of your library or folders for use in your LaTeX documents.
