Gantt Charts in Google docs
This Gantt Chart Google Docs article will show you how to create a Gantt Chart from your Google Docs spreadsheet. I have
posted a similar step
by step article that shows you how to make an Excel Gantt chart or
timeline. Many of the steps are similar.
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.
There is a lot of Project Management software available to manage projects but they create complex schedules that are often too confusing for executive
reporting or client reviews.
Google Docs are easily editable and accessible from the cloud which makes them useful for collaborating on projects. Although there is not a native
project management for Google apps solution, Google spreadsheets is perfectly suitable for tracking project schedules. When it comes time to present
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 Docs. If you have access to Microsoft PowerPoint I will show you how to turn your
Google Docs data into a beautiful Gantt chart and timeline, which may better suited for project reporting. The short video at the bottom of the page
demonstrates how to do this.

Google Docs Gantt Chart How To
Set up your Google project management spreadsheet by building a table for your project schedule.
As show below it should include the description of your tasks or phases, and the start and finish date for each of them.
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 ups like this:
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.
I called my second column “Start on Day.” Basically this column figures out how many days into the project will each of your tasks
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$7). This formula translates into: This Task’s Start Date – The First
Tasks Start Date (in my example cell F7).
See more Google Spreadsheet formulas here.
I called my third column “Task Duration in Days.” In this column Google Spreadsheet figures out how many days each of you projects tasks
will go on for. In my example the first task, Sourcing, will last for 77 days. Calculate this for each of you tasks using this Google
spreadsheet formula as show below: =(int(G7)-int($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) =
Click in the corner of your table and select the all the data in your new table.
Navigate to the “insert chart” icon on the Google docs ribbon and select “Chart” from the drop down menu.
On the Chart Editor, select the link for More.
In the Chart Editor, select the tab titled Charts and choose the Stacked Bar Chart.
In the Chart Editor, select the Customize tab and change the color of your first Bar to “None” as show in the
Once you have created your chart rename the horizontal and the vertical axis title, and click on the insert button.
