A more extensive gantt chart would also consists of lines connecting the tasks showing the dependencies of each task.
While we can use readily avaiable project tools to plot out the gantt charts, sometimes, we just need a avery simple high level gantt chart and it seems the easiest ways to do it is using Microsoft Excel as the charts can be easily distributed and Microsoft Excel provides many features for you to format the chart. Unfortunately, to do it manually takes time and we would like to look for easier to do that.
There are a few methods that one can use to create a Gantt Chart using Microsoft Excel. You can eithe user the Charting tool in Microsoft Excel to do it, or another very popular way of doing it is to use condition formating and some simple Excel formula to automate this task.
To create a gantt chart like the above in Excel is very easy. All you need is to use the condition formating for the gantt chart area. The formula would check if the cell date falls within the start and end dates of the task. So for example in Cell G 1, the formula would be:
That's all that you need to enter in the condition formating window for this cell. After that just duplicate this formula across to all the cells.
Of course there are tools that are available to help you plot this easily with many added functions. One such free too is XL-EasyGantt.
