Learning how to create a Gantt chart

I have currently learned how to create a Gantt chart using Microsoft Excel for the completion of my EPQ plan. I have used Tom's planner initially, however I was not able to print it off because I had to pay for the whole software in order to print. So I have incorporated the plan I had done and manually copied it into excel. With the help of internet resources such as "https://www.ablebits.com/office-addins-blog/2014/05/23/make-gantt-chart-excel/" I was able to create a Gantt chart. Additionally, I was not able to follow my original plan step by step due to some complications which I did not foresee, therefore, have changed the original plan to what I have actually done and will make a new plan to compare it to the original.
