Drawing routes (on road shapefile) between X,Y coordinates in QGIS

I've got a column with 300 of start points and 300 of end points (X,Y coordinates for each point).

I now want each row in the column to connect with each other (e.g. X,Y Coordinate for Start Point, ends where X,Y coordinate for end point). This for EACH row. So it will be a total of 300 routes.The data I want out from this is the length (km).

Excel File columns:

Example of row 1..3:

Each row is ONE (1) route.
