Build Your Project Schedule

Google Sheets provides the ability to create detailed Gantt charts in a spreadsheet. The steps are easy. Build a project schedule, create a calculation table, and then generate the Gantt chart. Before diving into Gantt chart creation, you first need to define your project tasks along with the corresponding dates in a simple table. Other formatting aspects of your table (such as borders, shading, alignment, and font styling) are arbitrary in this case since the primary goal is to enter data that will be used by a Gantt chart later. It’s completely up to you whether you’d like to make further modifications so that the table is more visually appealing. If you do, however, the data must remain in the correct rows and columns.

Create a Calculation Table

Inputting start and end dates isn’t enough to render a Gantt chart because its layout relies on the amount of time that passes between those two important milestones. To handle this requirement, create another table that calculates this duration:

Generate a Gantt Chart

Now that your tasks are in place, along with the corresponding dates and duration, it’s time to create a Gantt chart:

Task NameStart DayTotal Duration

If copied correctly, the Start Day value for each task reflects the number of days from the beginning of the project that it’s set to begin. To validate that the Start Day formula in each row is correct, select its corresponding cell and ensure that it is identical to the formula typed in Step 4. There’s one notable exception: the first value (int(xx)) matches the appropriate cell location in the first table. Your Gantt chart is created. You can view individual Start Day and Total Duration figures by hovering over the respective areas in the graph. You can also make other modifications from the chart editor, including dates, task names, the title, color scheme, and more.
