What’s a Gantt Chart?
A Gantt chart works as a master checklist for virtually any project: a product launch, a construction schedule, a marketing campaign, or even a conference. In an event planning context, for instance, it lists every task (booking the venue, sending invites, arranging catering), tells you when each one needs to happen (timeline), and makes sure you don’t print the attendee badges before the registration deadline has passed (dependencies or anchors).
If any of these terms sound different, don’t worry. We will explain them as they come up.
First conceived up by Henry Gantt in the early 1900s, this humble variation of the bar chart has outlasted fax machines, overhead projectors, and at least three generations of project management software. If you work in consulting, corporate planning, or any role where projects involve more than one human being, a well-built Gantt chart is the difference between a presentation that earns nods and one that earns confused silence.
Gantt Charts in PowerPoint
Here is something worth knowing: native PowerPoint has never officially supported Gantt charts. Not in PowerPoint 97, not in PowerPoint 2016, not even in the latest Microsoft 365 or Copilot version. Every Gantt chart you have ever seen built in PowerPoint is, technically, a workaround dressed up in a suit.
And those workarounds have a cost. You spend an hour wrestling a stacked bar chart into something that vaguely resembles a Gantt chart, adjust the colors, nudge the labels, and then your project dates change. Back to square one. Yes, Ampler changes that roundabout workaround entirely, bringing built-in Gantt chart functionality into PowerPoint without the manual acrobatics.
Ampler is headquartered in Copenhagen, Denmark, a city that also gave the world Lego, known worldwide for its simple, modular building blocks.
What are Ampler, or Ampler Charts?
Ampler is an add-in suite for Microsoft 365 applications built by ex-Bain consultants. They also provide the Ampler Charts add-in, which is a subset of Ampler. Both options contain charting tools used in consulting, but not available in the native Office environment. The result is an add-in that covers all the chart types that matter most in professional presentations: waterfall, Mekko, combination charts, and yes, Gantt charts.
The Ampler Charts-only plan is priced at €12 per month, making it one of the more affordable options among PowerPoint charting add-ins. For those who work extensively across Microsoft Office, the full Ampler Suite at €30 per month extends the same productivity gains to Excel, Word, and Outlook.
Before we dive in, a quick word about the team behind Ampler. Our primary contact for this review was Sune Høj Kodahl, and we are grateful for his patience in answering our many questions. We also thank Morten Gadegaard for his prompt and helpful responses throughout the review process.
Users can download a trial version of Ampler or Ampler Charts directly from the Ampler website.
Inserting a Gantt Chart Using Ampler
Follow these steps to get started with Gantt charts in PowerPoint using Ampler:
- Launch PowerPoint with the Ampler or Ampler Charts add-in active. You typically will see a slide with a Title and Content layout. We will now change our slide layout to Title Only. To do so, access the Home tab of the Ribbon. Next, click on the Slide Layout button, highlighted in blue within Figure 1, below. In the ensuing drop-down gallery, choose the Title Only option, highlighted in red within Figure 1.
Figure 1: Change layout to Title OnlyWhy the Title Only Layout?
Why did we choose the Title Only layout rather than the Title and Content or any other layout? Is it more suitable for charts created using Ampler in PowerPoint? Yes, the Title Only layout works well for charts because it gets out of the chart’s way. Layouts like Title and Content come with a content placeholder that is sized for bullet text or modest objects, leaving less room for a chart to breathe.
A chart usually needs more room to breathe, especially with a legend, axis labels, and data labels all competing for space. Title Only gives you just the title bar up top and leaves the rest of the slide as open real estate, so the chart can be sized as large as the data actually needs.
- Figure 2, below, shows you the active slide with the Title Only layout. As you can see, we typed some text content into the Title placeholder.
Figure 2: Title Only slide- If you have the entire Ampler add-in installed, access the Ampler tab of the Ribbon. If you have the Ampler Charts add-in installed, access the Home tab of the Ribbon. Either way, you will find the Ampler Charts button, as shown highlighted in red within Figure 3, below.
Figure 3: Bring up Ampler Charts- Click on this button, and you will find an assortment of chart types. Choose the Gantt option, as shown highlighted in blue within Figure 3, above.
- Your slide area will now see a highlighted rectangle, as shown in Figure 4, below. Drag and drop this rectangle placeholder wherever you want. The initial placeholder is simply a starting point. The Gantt chart you create can be resized and moved to wherever it works best on the slide.
Figure 4: Place the rectangle placeholder- Ampler places a sample Gantt chart with some dummy data on your slide, as shown in Figure 5, below. At this point, you have already created and placed a Gantt chart. The chart is now ready for your data. Replace the dummy content and customize the relevant parameters to suit your project.
Figure 5: Gantt chart placed on your slide- The datasheet does not open automatically when the Gantt chart is placed. Having said so, there is nothing to worry about as it is easy to access when needed.

What is the Datasheet?
The datasheet is where your project plan takes shape: activity names, start dates, end dates, and dependencies. Additional columns for responsible persons and comments are available, which is useful when presenting to stakeholders who expect accountability alongside timelines. If you have not seen the datasheet yet, then you’ll be glad to know that it’s just another Excel sheet. To bring up the datasheet, hover your cursor over the bottom-right area of the Gantt chart, and you will see an Excel icon, as shown highlighted in blue within Figure 6, below.
Figure 6: Edit data in ExcelClick on this icon and Excel will show up, as shown highlighted in red within Figure 7, below. Place this Excel sheet a little apart from the slide and try making some edits. You will see the changes instantly in your Gantt chart. Most changes are easy to make, and some even provide fixed options, as shown highlighted in blue within Figure 7. If you end up with something unintended, just press Ctrl + Z to undo.
Figure 7: Update data for the Gantt chartClose the datasheet and the chart is ready to use. That said, most data entry can also be done directly on the slide, without opening the datasheet at all.
Editing the Gantt Directly on the Slide
One of Ampler’s more practical features is direct on-slide editing. Click any Gantt element and move your cursor to the edge that you want to enlarge or reduce. You will see the Plus cursor, as shown highlighted in red within Figure 8, below. Drag this cursor to shift dates or adjust duration. This is a useful capability during live and interactive review sessions where plans change on the spot, and you do not have time to bring up the datasheet. When finer adjustments are needed, opening the datasheet is always an option.
Figure 8: Drag to resize activities and tasks
For non-numerical values such as tasks and activities, you can select and overtype easily, as shown highlighted in red within Figure 9, below. The best part is that these direct edits get updated in the datasheet as well.
Figure 9: Edit directly on the Gantt chart
Right-clicking the chart, or even any individual chart element brings up a contextual menu. To select the entire Ampler chart, click on the edge of the chart so that it is selected. Then, carefully right-click so that you see a contextual format menu with choices that influence the overall chart, as shown highlighted in red within Figure 10, below.
Figure 10: Right-click menu for the entire chart
Similarly, you will see different contextual menus, depending upon what you right-click. If you right-click on a single Activity (task), you will see options highlighted in red within Figure 11, below. You can add activities and row separators and delete activities.
Figure 11: Right-click menu for a selected activity
You can similarly bring up contextual menus that toggle borders, set the date range, and choose which scales and separators are displayed.
Linking to Excel
What if you already have all the data to create a Gantt chart within an Excel spreadsheet? Do you need to type in the data again within your Ampler chart? Not really, because Ampler can connect directly to it. Left-click on the Gantt chart, and you will see the menu shown in Figure 12, below. Click on the Establish Excel link option, highlighted in red within Figure 12. A window opens where you highlight the relevant data range in your Excel file. Once you return to PowerPoint, the Gantt chart updates to reflect that data.
Figure 12: Establish Excel link option
The Establish Excel link option is also available in the right-click menu, shown in Figure 10, earlier on this page. Keeping the chart current is straightforward: after updating your Excel file, right-click the Gantt chart. In the ensuing menu, select Refresh linked data, highlighted in red within Figure 13, below. The same menu offers a Break Excel link option, highlighted in blue, for when the connection is no longer needed. If you need to point the chart to a different Excel file, the Modify Excel link option, highlighted in green, handles that as well.
Figure 13: Refresh, modify, or break Excel links
Milestones and Anchors
Ampler’s Gantt charts can include milestones. Milestones are typically displayed as diamonds on the chart and indicate important deadlines or deliverables. In a conference planning project, for example, a milestone might mark the date by which all speaker confirmations must be received. It sits on the timeline as a single point rather than a duration bar, which makes it visually distinct and easy to spot during a presentation.
Follow these steps to add a milestone in your Ampler Gantt chart:
- Right-click on the point where you want to add a milestone. In the resultant menu, choose the Milestone option, shown highlighted in red within Figure 14, below.
Figure 14: Add a milestone- Ampler adds a milestone in the form of a Diamond shape, at the point you clicked, as shown highlighted in red within Figure 15, below. Notice that the milestone also has a label with the date, but there is no milestone line.
Figure 15: Milestone is added with a label- To add a line or make more changes, right-click the Diamond shape. In the resultant menu, select the Milestone line option, highlighted in red within Figure 16, below. You can also disable the Milestone label option in the same menu.
Figure 16: Milestone options
Ampler allows you to link two activities so that the end of one activity is directly related to the beginning of another activity. In simple terms, this means that if you increase the time taken for the previous activity, the start time of the subsequent activity is automatically adjusted. To make this apparent in a Gantt chart, Ampler can anchor processes and bars.
Follow these steps to understand better:
- Select an activity bar in your Gantt chart, and you will see handles, as shown in Figure 17, below. Click the rightmost handle, as shown highlighted in red.
Figure 17: Selected activity bar- Now drag this handle to the second bar that you want to anchor with. As you drag closer, you will be able to snap with the selection handle in the other bar, as shown highlighted in red within Figure 18, below. Let go off the dragging to create the anchor
Figure 18: Connect with another bar- The bars are now connected, and resizing one bar will make the other bar shorter or longer. To be sure that there is an anchor established, you can right-click on the rightmost handle of the first bar, and you will see the contextual menu, shown in Figure 19, below. Notice the Unanchor end option, highlighted in red. You can click on this option to remove the anchoring.
Figure 19: Unanchor option
Formatting and Brand Consistency
Ampler gives you precise control over every visual element of your Gantt chart. Here is how to approach formatting:
1. Colors
Click any element on the chart to select it. Doing so brings up a floating pane similar to PowerPoint’s Mini Toolbar, as shown highlighted in red within Figure 20, below.
Figure 20: Floating pane
Within this floating pane, you will find the Color option, highlighted in blue within Figure 20, above. Click on this option to bring up PowerPoint’s default Theme colors, as shown in Figure 21, below. You can choose a new color, or even click on the handy Eyedropper option, highlighted in red within Figure 21. This works like PowerPoint’s Eyedropper option.
Figure 21: Theme colors and Eyedropper option
2. Borders
Ampler includes an option to show or hide left and right borders on the Gantt chart, which gives the chart a cleaner, less boxed appearance when needed. In fact, this is the default option.
If you want to show left and right borders, right-click on the entire chart, and you will see the floating pane, shown highlighted in red within Figure 22, below.
Figure 22: Show left and right borders
Now, click on the Show left and right borders button, highlighted in blue within Figure 22, above.
3. Labels and indentation
You can indent labels, especially those in the Activity pane on the left to group sub-tasks under a parent activity. The resultant indents create a sense of hierarchy.
To do so, click on any label, and you can see the contextual pane shown highlighted in red within Figure 23, below.
Figure 23: Indent your labels
Click the Increase indentation option, highlighted in blue within Figure 23, above, to indent the text within the label rightwards. You also have a similar Decrease indentation option, highlighted in green. Notice that this same pane also provides options to set Activity levels and add Bullets.
4. Company themes
Here is a scenario every consultant knows. You finish a Gantt chart at midnight, send it to a colleague, and get it back the next morning in the wrong shade of blue with a different font. Brand consistency in presentations is one of those problems that sounds minor until it isn’t. Ampler’s Company Settings feature solves it quietly and permanently.
Configure your organization’s colors, typography, and chart themes once, and every chart built in Ampler, including Gantt charts, inherits that visual identity automatically. No reminders, no corrections, no midnight emails.
Saving and Reusing Layouts
Here is something most PowerPoint users have experienced at least once. You build a beautiful Gantt chart, get the colors right, nail the font size, and then three weeks later you need another one and cannot remember how you did it. Or you don’t want to spend so much time making the same choices. Back to square one. Ampler’s Save Chart Layout feature puts an end to that particular frustration. Save your preferred design once and it is available every time, ready to populate with new project data without touching the formatting.
Follow these steps to use the Save Chart Layout option:
- Select the chart that you want to save the layout for and click once on the edge of the chart. You will see the pane that you see in Figure 24, below. Now click on the Chart layout drop-down, shown highlighted in red within Figure 24.
Figure 24: Chart layout drop-down- In the ensuing gallery, click the Save chart layout option, highlighted in red within Figure 25, below.
Figure 25: Save chart layout- You will see the Save chart layout dialog box, as shown in Figure 26, below. Select a template category, as shown highlighted in red within Figure 26, then provide a name for your customized layout, as shown highlighted in blue, and finally click the Save button, highlighted in green.

Keeps Your Team on Brand
Consistency in visual presentation is one of the top factors that makes a deck look professionally produced rather than assembled in a hurry. Pair the Save Chart Layout feature with Ampler’s Library, which stores and shares slides, shapes, and templates across your team, and you have a workflow that is genuinely built for repeated, high-quality output.
Do note that the Library feature is not part of Ampler Charts and needs the full Ampler suite. Ampler also provides the Library option as a separate product.
The Practical Case for Ampler
Creating a Gantt chart in native PowerPoint is possible but tedious. The same chart in Ampler takes a fraction of the time, looks significantly better, and is far easier to maintain as plans change. The Excel link alone justifies the add-in for anyone who updates project timelines regularly.
At €12 per month for the Charts-only plan, Ampler is one of the more affordable dedicated PowerPoint charting tools available. For consultants, project managers, and anyone who presents project plans with any frequency, it is a practical upgrade worth considering.
Gantt charts tell a story: where a project starts, where it ends, what happens in between, and who is responsible for what. Ampler makes sure that the story is told clearly, consistently, and without unnecessary effort.
Conclusion
Gantt charts have been a staple of project planning for over a century, and yet PowerPoint has never officially supported them. Ampler closes that gap cleanly and efficiently. Whether you are linking to an existing Excel file, dragging tasks to adjust timelines on the fly, or applying company-wide brand settings across every chart, the experience is noticeably smoother than anything native PowerPoint can offer. For consultants, project managers, and presenters who work with project timelines regularly, Ampler makes a compelling case for itself, one Gantt chart at a time.
