You start by entering your project's data in an Excel spreadsheet. Only the Start date and Duration columns are really necessary for creating an Excel Gantt chart.
Most likely, spreadsheets to input data, formulas to perform calculations and charts to create graphical representations of various data types.But I think the above approach is better because Microsoft Excel will add one data series to the chart automatically, and in this way save you some time. You have to add the proper formatting to make it look more like a Gantt chart.A Gantt diagram in Excel represents projects or tasks in the form of cascading horizontal bar charts.A Gantt chart illustrates the breakdown structure of the project by showing the start and finish dates as well as various relationships between project activities, and in this way helps you track the tasks against their scheduled time or predefined milestones.
Please follow the below steps closely and you will make a simple Gantt chart in under 3 minutes.We will be using Excel 2010 for this Gantt chart example, but you can simulate Gantt diagrams in Excel 2007 and Excel 2013 exactly in the same way.
