Why use project management visuals

A Gantt chart is a critical project management tool for anyone working on a project. Gantt charts help visualize the project schedule and status, which makes them useful particularly when communicating with project stakeholders.

Google Sheets Project Management

There is a lot of Gantt chart software available to manage projects, but these tools create complex schedules that are often too confusing for executive reporting or client reviews.

Google spreadsheets are easily editable and accessible from the cloud, which makes them useful for collaborating on projects. Although there is no native Google apps solution for project management, Google Sheets is perfectly suitable for tracking project schedules. When it comes time to presenting those schedules to customers or management, you will need to create a Gantt chart.

I will show you how to easily create a simple Gantt chart in Google Sheets. If you have access to Microsoft PowerPoint, I will show you how to turn your Google spreadsheet into a beautiful Gantt chart or timeline, which may be better suited for project reporting. The short video at the bottom of the page demonstrates how to do this.

Below I will demonstrate how to manually create a simple Gantt chart in Google Sheets. If you wish to create more professional visuals for high-level presentations, I will show you how to instantly turn your data into a beautiful Gantt chart using a free browser-based tool called Office Timeline Online.

How to manually make a Gantt chart in Google Sheets

Step 1

Set up your Google project management spreadsheet by building a table for your project schedule. As shown below, it should include the description of your tasks or phases and the start and finish date for each of them.

Step 2

Add a second table underneath. The purpose of this table will be to calculate the intervals in days (duration) between the start date and the finish date. These intervals will be used to build your Gantt chart. The 3 columns in this table will reflect the 3 columns in your original table. Set it up like this:

  1. The first column will be your Task Descriptions copied exactly from your original table. In my new table, I called them “Critical Tasks”. To copy them from your original project schedule with a formula, in the first cell of your new table type “=” and then click on the cell with the title of your project description in the original table. You can repeat or simply drag the corner of this cell downward and your formula will be copied for each of your task descriptions.

  2. I called my second column “Start on Day.” Basically this column figures out the day into the project each of your tasks will begin on. So the first/earliest task will obviously start on day 0. To calculate this column, use the following Google spreadsheet formula as shown below: =int(F7)-int($F$7) and in the cell beneath =int(F8)-int($F$7). This formula translates into: This Task's Start Date – The First Task's Start Date (in my example, cell F7). See more Google Spreadsheet formulas here.

  3. I called my third column “Task Duration in Days.” In this column, Google Spreadsheet figures out how many days each of your project's tasks will go on for. In my example, the first task, Sourcing, will last for 77 days. Calculate this for each of you tasks using this Google spreadsheet formula as shown below: =(int(G7)-int($F$7))-(int(F7)-int($F$7)) and in the cell beneath =(int(G8)-int($F$7))-(int(F8)-int($F$7)). This formula translates into: (This task’s End Date – the first task’s start date) – (this task’s start date – the first task’s start date) = Task Duration.
