Ben Franklin (and La Fayette).
The key colonists who convinced the French to aid the American colonies during the Revolutionary War were Benjamin Franklin, John Adams, and Silas Deane. Franklin, in particular, played a crucial role in diplomacy, leveraging his charm and political acumen to secure French support. Their efforts culminated in the Treaty of Alliance in 1778, which formalized military assistance from France. This alliance was pivotal in helping the colonies achieve victory over Britain.
Benjamin Franklin!
Battle of Saratoga
The Battle of Saratoga is usually considered the "turning point" in the American Revolution. Not only did it stop the British plan to divide the colonies, but it convinced the French that the colonists had a chance to defeat England and the French government agreed to recognize the new nation and to come to its aid with financial help and military aid, especially the French Navy.

It convinced the French to recognize American independence and provide military aid.
Assuming you mean the American Colonies against England: France and England had previous tension with each other (hence the French and Indian war, where France hired the Native Americans to attack English settlers in the American Colonies) so, when the Americas told France of their endeavours and convinced them that they were a substantial force, France hopped on board seeing an opportunity to attack England.
The French monarchy wanted to reduce the power of the British, and gain revenge for the loss of Quebec following the French and Indian War (aka. the Seven Years' War). Great Britain returned Tortuga to France as a result of the Revolutionary War.
It convinced the french government to support Americans and provide them aid (military and financial assistance). This ultimately helped America defeat Great Britain!
Following the French and Indian War (or The Seven Years' War), the British and French still had clear, bitter tensions among one another. The French wanted to get revenge for the British's actions in the French and Indian War. When the American Revolution began in 1775 and the colonists sought aid, the French were skeptical of any positive outcome. However, in 1777, at the Battle of Saratoga, the colonist victory proved to the French that the Colonial Army was capable of taking on the British. On the request of Benjamin Franklin, the French Army later sent aid, and in 1783, the war for American Independence was over.
