Select the required literature, and then click Open. A mark will appear in the upper right corner of the document. Click Export.

After export, the standard format of the reference will be displayed directly.

Select a document. Mode, and save it directly to the font after export.

Saving to word is such a form. If your school's recommendation letter writing format is different from this, you can make some adjustments yourself.

Special note: I hope this method is helpful to everyone.
