Hello @Alexandre,
Community server v12.5 is released since a few days, however I can’t find any traces of this feature, did it get postponed ?
Regards
edit: My bad, found it : Add external links to cells - ONLYOFFICE ( introduced here ONLYOFFICE Docs v7.3 released: enhanced forms and security, SmartArt, Watch Window, and more )
edit2: did a quick test on your online version, link will work during paste however every value will be filled with 0’s after update (either by menu>data>external links>update or after reloading the file)
