Joncourt was a very prolific and eclectic translator, working in Latin, French, English and Dutch. He published his editions mainly in The Hague.
Religious works constituted a considerable part of his publications, ranging from sermons of English theologians translated into French to books from the Bible. For the latter, he benefited from the help of his fellow journalist and editor at the Journal littéraire Jacques Sacrelaire, which enabled him to compose a French version of the Latin translation by the Hebrew philologist Albert Schultens.
Joncourt's interest in mathematics and philosophy led him to translate and distribute diverse Newtonian treatises and ideas from across the Channel. He accordingly also encouraged French and Dutch editions of Willem Jacob 'sGravesande's main works. 'sGravesande was Joncourt's fellow citizen, colleague and main source of inspiration.
In addition, Joncourt published translations of Alexander Pope's complete Works and George Lyttelton's Dialogues of the Dead, showing a personal awareness and sensibility to poetry. As a journalist, he published a couple of volumes of Joseph Addion's Spectator and after his retirement he started the journal Nouvelle Bibliothèque Angloise (1756-1757) in The Hague, to review the scientific and literary novelties of the United Kingdom and publicize his own translations.
Joncourt eventually translated his own mathematical treatise from Latin to Dutch and French.
