When opened for the first time, the basic version adds two worksheets: Project and Tasks, the Pro version adds four worksheets: Project, Tasks, Resources and Holidays. The Project worksheet shows a summary of the project. In the Holidays worksheet you can enter dates on which the project is not working.

Gantt chart in spreadsheet

The Tasks worksheet is shown in the screenshot below and consists on the left side of a table with the schedule and on the right side of a generated Gantt chart. On the far right is the add-in's task pane. When edits are made in the spreadsheet or task pane, the schedule and Gantt chart are updated during the wait period, indicated with the wait color at the top of the task pane.

screenshot of Excel with add-in

The Start and Finish dates correspond to bars in the Gantt chart. The WBS code indicates how the tasks are structured with summary tasks.

The start date of the summary task equals the earliest start date of its subtask(s), the finish date of the summary task equals the latest finish date of its subtask(s).

screenshot with Gantt bars

The progress percentage corresponds to a double line in a bar.
The date of today is shown with a vertical dashed blue line in the Gantt chart.
A task is blue, a summary task is gray and a milestone is orange.
When present, the background color of the Task description is shown as the color of the bar. If you change the color, click the Refresh Gantt button to update it.

The Pro version shows a link between tasks in the Gantt chart with an arrow and progress with a solid bar inside the Gantt bar.

The Gantt chart shows the entire schedule or a part of it, depending on the timescale set in the Settings tab in the task pane. You can set the Start date of the timescale to scroll through the Gantt chart. The Start date can be set with the date picker or to today or to the earliest start date if the selected tasks. You can set the Time period of the timescale to see the entire project in the Gantt chart (in Pro only). The Time period starts with 1 day per cell and ends with 3 years for the entire timescale (18 days per cell). Both Start date and Time period are set automatically with Autofit (in Pro only).

These up/down buttons in the Edit tab move to the previous/next task row. The spreadsheet row index is shown behind the buttons.

This dropdown in the Edit tab has functions to collapse/expand selected or all summary tasks.
The 'collapse level' function collapses all summary tasks with the same indent level as the selected summary task.
The 'hide 100% completed' function hides all (summary) tasks that have 100% progress.

Start and Finish dates

The Start column contains the start date of a task, the Finish column the finish date. The summary dates and Gantt chart are calculated when applicable. For the basic version a task becomes a milestone if it only has a finish date.

Duration (Pro only)

The duration of a task is the time between Start and Finish date. When changed, the Finish date is recalculated, while the Start date is kept. When the Finish date is changed, the Duration is changed while the Start date is kept. A task becomes a milestone if it has a duration of 0.

This task will go from italic to bold in the task pane. Then click on a task and on 'to'. You can repeat this for more 'to' tasks. Clicking on 'to' again will unlink. You can also do this reverse with 'to' and one or more 'from' tasks. After linking you can change the type and lag/lead time in days and hours.

FAQ - Frequently Asked Questions

How to expand the timescale of the Gantt chart?

Do not change the Gantt chart in the spreadsheet itself. Change the Start date and Time period (in Pro only) of the chart in the Settings tab of the task pane. By changing the Start date you can scroll through the Gantt chart.

Why are the dates in the Gantt scale 4 years and 1 day earlier than the dates in the Start and Finish cells?

Excel has two date systems, Windows always uses the 1900 system, Mac also uses the 1904 system. ProjectSheet for Excel uses the 1900 system. Here you can read how to switch from the 1904 date system to the 1900 date system in Excel, depending on your Excel version: Date systems in Excel.

How to solve "Add-in Error. We couldn't connect to the 'Office Store' catalog server for this add-on"?

If your company supplies Microsoft Office 365 to you, you can check with the administrator if ProjectSheet - Gantt chart can be added in the Admin Center from the Office Store (Settings > Integrated apps).

Why are the Gantt bars sometimes not aligned with the tasks in the Pro version?

This may happen when the spreadsheet zoom level is not 100%, as a result of an issue in the Microsoft framework. As a workaround there is the basic Gantt option at the bottom of the task pane on the right.

What is the minimum requirement for this Excel add-in?

The Microsoft AppSource store states Excel 2019, the minimum Excel version required is the 1808 (2018, August) update. You can find your version under Account > About Excel.

Can I transfer my license to another account when I leave the company?

Not your license, but you can transfer your remaining time to another active license. Send a request for transfer to the Helpdesk in which you mention the other active license account. The remaining time is then added to the license end date of the other account and your own license is terminated.

How to remove the add-in?

Find the ProjectSheet add-in in the Insert ribbon under Office Add-ins in the MY ADD-INS tab. Click on the three dots for the menu and choose remove. If ProjectSheet is not there, you can look in the ADMIN MANAGED tab and ask the administrator.
Make sure that you remove the add-in from all the desktop Excel apps that you used on all your devices and also from Office online, to prevent a task pane with a Trust this add-in button when you open the spreadsheet again.
