You can use the following SQL query to insert multiple rows just using a single INSERT statement:
INSERT INTO MyTable (Person, Id, Office) VALUES
( Value1, Value2, Value3 ), ( Value1, Value2, Value 3)
INSERT INTO MyTable (Person, Id, Office)
VALUES ('John', 123, 'Lloyds Office'),
('Jane', 124, 'Lloyds Office'),
('Billy', 125, 'London Office')
