Project managers who use visual planning tools deliver 45% more projects on time, according to PMI research. A Gantt chart is the simplest visual — tasks, durations, dependencies, all on one timeline. This Project Timeline is ready to use today.

What’s inside this Project Timeline template

• Colour-coded status — not started, in progress, on hold, and complete shown visually per task
• Baseline comparison — original planned dates shown alongside current dates to track schedule slip
• Summary row — automatic calculation of overall project completion percentage
• Export for client sharing — a clean version with internal notes hidden, ready to share in one click

How to use this Project Timeline template

1. Get access to the Gantt template and save a copy to your Drive.
2. List all project tasks in the task column, grouped by phase or workstream.
3. Enter start and end dates for each task — the Gantt bars generate automatically.
4. Assign an owner to each task and mark any dependencies in the notes column.
5. Update progress percentages weekly — the chart reflects changes immediately.

Why Google Sheets for Project Timeline?

The best project timeline is the one the whole team trusts. A Google Sheets Gantt chart updated by the people actually doing the work — rather than a PM re-entering data from emails — stays more accurate than any dedicated tool.

Frequently asked questions

How many tasks can the Gantt chart handle?

As many as your project requires. Add rows at any time and the chart extends automatically. Google Sheets handles hundreds of tasks without performance issues.

Can I share this with clients or stakeholders?

Yes. Share the link with view-only access for external parties. They see the same live timeline you do without being able to edit the underlying data.

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.
