PMI research shows that 70% of projects run over schedule or budget when there is no visual timeline. The moment your project has more than three moving parts, a Gantt chart stops being optional. This Project Timeline gives you that visual in minutes.

Google Sheets Gantt charts are shareable with one link — clients, contractors, and stakeholders all see the same timeline the moment it updates. No software licence required, no account for them to create.

Frequently asked questions

Does the chart update automatically when I change dates?

Yes. Edit the start or end date of any task and the Gantt bar repositions immediately. No manual chart adjustments required.

Can I show dependencies between tasks?

The template includes a dependency notes column. For visual dependency lines, use the conditional formatting guide in the instructions tab to add connecting markers between linked tasks.

How do I use this for multiple projects?

Duplicate the project tab for each new project. Add a portfolio summary tab that shows the status and completion percentage of all active projects in a single overview.
