This Excel tool is very helpful to calculate gas compressibility (Cg). This gas properties is estimated from gas formation volume factor that has been calculated from the previous post. On input, you have to provide gas specific gravity (air=1), gas composition (CO2 and H2S), and temperature. Gas  formation volume factor calculation is provided in this tool. Gas compressibility is asymptotically approached as the pressure decrease.

Use VBA macro? Yes
