Platt attended Huntington Academy and Ashland Hall in West Bloomfield, New Jersey. He then went to Princeton College, graduating from there in 1858 as the youngest member of his class. He then studied law in the office of Van Winkle & Halsey. He was admitted to the bar in 1863.

In 1863, Platt was elected to the New York State Assembly as a Democrat, representing the Suffolk County 2nd District. He served in the Assembly in 1864 and 1865.

In 1886, Platt moved to New York City and practiced law there. President Cleveland appointed him Assistant United States Attorney for the Southern District of New York, a position he retained under the President Harrison. In 1894, he became the United States Attorney to fill a vacancy caused by Edward Mitchell's term expiring. Wallace Macfarlane was then appointed United States Attorney, and Attorney General Olney appointed him Assistant United States Attorney. He served that position until July 1904, when he resigned due to poor health.
