JabRef can export databases to EndNote-readable files. To use this feature, choose File → Export, choose the file type Endnote (txt) and then specify the name of the export file.
The default EndNote Import filter does not handle multiple authors or editors properly. There are two options to work around this:
Use the built-in filter and fix the file later. To open up the file in EndNote, create a new database or open an old database in EndNote. Then select File → Import, click on Choose File, then highlight the exported file and click Choose. Click on Import Options and select EndNote Import. Click Import to start the import. After import, select Edit→ Change Text. Change Any Field to Author. Enter " and " into the search field (without quotes). enter a return character into the change field (Option + Enter on Mac OS X, Ctrl + Enter on Windows XP). Click Change. Repeat with the Secondary Author field.
Install the EndNote Import from JabRef filter in the EndNote Extras. Follow the instructions in Advanced Use below. To open up the file in EndNote, create a new database or open an old database in EndNote. Then select File → Import, click on Choose File, then highlight the exported file and click Choose. Click on Import Options and select EndNote Import from JabRef (if it does not appear, select Other filters. If it still doesn't appear, it was not correctly installed.) Click Import to start the import.
The EndNote Export filter maps BibTeX entrytypes to EndNote reference types as follows:
BibTeX entrytype -> EndNote Reference Type------------------------------------------misc, other -> Genericunpublished -> Manuscriptmanual -> Computer Programarticle -> Journal Articlebook -> Bookbooklet -> Personal Communicationinbook,incollection -> Book Sectioninproceedings -> Conference Proceedingstechreport -> Reportmastersthesis, phdthesis -> Thesis
By default, the export filter assumes that entries in the author or editor fields in brackets are corporate authors and replaces the brackets with a trailing comma. However, this means that entries that include LaTeX code in brackets will be assumed to be corporate authors and therefore will be improperly formatted.
For better interoperability between EndNote and JabRef, download the EndNote filter set from the Resources page of JabRef's web page.
