Free Google Sheets Project Timeline Template (2026)
Copy a free Google Sheets project timeline template with example and blank tabs, owners, dates, status, manual dependencies, and a 28-day Gantt view.
New in Kanban Tasks: Gantt charts in Kanban Tasks.
Use this free Google Sheets project timeline template to plan tasks, owners, dates, status, and dependencies in one shared file.
Copy the Google Sheets project timeline template
There is no lead form. Google asks you to sign in so it can save the copy to your Drive. The file has two tabs: Example timeline shows a filled project, and Blank timeline gives you 20 editable task rows.
If you cannot use Google Sheets, download the Excel version.
What the template includes
| Field | Example | What to enter |
|---|---|---|
| ID | 3 | A unique number for the task |
| Task | Approve launch copy | A specific deliverable or action |
| Owner | Maya | One person responsible for the task |
| Start | 14 September 2026 | The planned start date |
| Finish | 16 September 2026 | The planned finish date |
| Days | 3 | The task duration calculated from Start and Finish |
| Status | In progress | The current state from the status dropdown |
| Depends on | 2 | The ID of the task that must finish first |
The 28-day timeline starts at cell D4 and uses Start and Finish to draw each task across the calendar. The Depends on value is a manual task reference. It does not reschedule other rows automatically.
How to use the Google Sheets project timeline template
- Select Copy the Google Sheets project timeline template and make a copy in your Google Drive.
- Review Example timeline, then open Blank timeline.
- Set the first day of the timeline in D4. The sheet displays 28 days from that date.
- Add one row for each task. Give it a unique ID, one owner, a Start date, and a Finish date. The Days value is calculated for you.
- Select a status from the dropdown. In Depends on, enter the ID of the predecessor only when one task must wait for another.
- Share the sheet with the people who need to edit it. Use Viewer access for stakeholders who only need progress updates.
Keep task names short and concrete. “Launch page” is clearer when split into “Draft launch copy,” “Build campaign page,” and “Approve final page.” This makes ownership and delays visible.
Set up the timeline correctly
Use real dates
Enter dates as Google Sheets dates, not as text. Blank date cells stay blank, and changing Start or Finish moves the timeline bar. A reversed range, where Finish is before Start, does not produce a valid task bar; correct the dates before you use the plan.
Give each task one owner
A shared owner such as “Marketing team” hides responsibility. Put one accountable person in the Owner column.
Keep status separate from dates
Dates show the plan. Status shows what is happening now. Do not move a Start date only to make a late task look on time. Update the status or change the plan openly.
Review tasks that depend on other work
The Depends on column stores the predecessor task ID. If an earlier task moves, review its dependent rows and change their dates yourself. The template does not schedule dependencies automatically.
Protect formula and timeline cells
If several people edit the sheet, protect the formula and timeline ranges. Leave the task-input columns open. This reduces accidental changes to conditional formatting and date formulas.
Common Google Sheets timeline problems
| Problem | Cause | Fix |
|---|---|---|
| No timeline bar appears | A date is blank, stored as text, or outside the 28-day view | Enter a valid date or change the first timeline day in D4 |
| A bar starts or ends in the wrong place | Start and Finish are reversed or outside the displayed range | Correct the dates or change D4 |
| Dependent work is now late | A predecessor moved | Review the Depends on column and update affected dates |
| The sheet is difficult to scan | Tasks are too broad or the file contains too many projects | Split large tasks and use one tab or file per active project |
When a spreadsheet is enough
Use a Google Sheets project timeline when the plan has a clear finish, the group is small, and one person can maintain the dates. It is a good fit for a campaign, event, client deliverable, website launch, or a short internal project.
A sheet also works well as a stakeholder view. People can open one link and see the dates without learning another tool.
When to move from a timeline to a shared board and Gantt view
A spreadsheet becomes harder to maintain when work arrives continuously, tasks often change owner, or the team needs comments and attachments with each item. At that point, use a shared board for daily execution and a Gantt view for dated work.
Kanban Tasks keeps the same basic structure:
- board lists show the current stage of each task;
- assignees show ownership;
- due dates and date ranges show scheduled work;
- comments and attachments keep context with the task;
- the Gantt view shows dated tasks across a timeline.
Use the sheet to agree on the first plan. Then create the active tasks on a shared board when the team needs live ownership and regular updates. This avoids keeping two detailed systems in sync.
See the Kanban Tasks board and Gantt workflow or open Kanban Tasks. Personal use is free. Teams with shared boards and assignments cost $5 per user per month or $50 per user per year.
Google Sheets timeline template questions
Is this Google Sheets project timeline template free?
Yes. You can copy the template without an email gate and keep the copy in your own Google Drive.
Does the template include a filled example and a blank version?
Yes. Use Example timeline to inspect the completed setup and Blank timeline for your own project.
Does the template make a Gantt chart?
It creates a simple 28-day Gantt-style timeline from each task's Start and Finish dates. It is suitable for a clear shared plan. It does not calculate a critical path or reschedule dependencies automatically.
Can several people edit the timeline?
Yes. Use Google Sheets sharing controls to give Editor, Commenter, or Viewer access. Protect formula ranges before several editors start work.
How do I move the plan into Kanban Tasks?
Create a shared board and add active work as tasks. Assign an owner and dates to each task, then use comments, attachments, and the Gantt view to track progress.
