["first row is header data starts from row 2 you can see col A AND col C (ROW 2) data matches with COL E AND COL G(ROW 4 AND 5), LIKEWISE col A AND col C (ROW 3) data matches with COL E AND COL G(ROW 3 AND 6), LIKEWISE col A AND col C (ROW 4) data matches with COL E AND COL G(ROW 2 AND 7)\nSo if matches i want to replace the value Col B to F AND Col D to H"]
