CorelDRAW seems to have a special option to export .cdr files directly for Microsoft Office programs. You can achieve the cdr to doc conversion via the File ► Export for Office... function that essentially sends your document to MS Word for example, where you can save it in a document. This requires both CorelDRAW and Microsoft Office to be installed on your computer however.
If you do not have access to Corel programs, some 3rd party alternatives might also allow you to convert cdr to doc, or at least some kind of export.Open CDR file Open DOC file
