SharePoint Gantt Chart: Create a Gantt View in a SharePoint List (2 Ways)

A SharePoint Gantt chart comes from the Gantt View of a Tasks list: add the Tasks app, then pick Gantt View under LIST > Create View. Modern lists don’t offer that view type, so there you draw the bars with JSON view formatting.

In this tutorial, I’ll show you both ways to build a sharepoint gantt chart: the classic Gantt View with progress and dependency arrows, and a JSON Gantt view for a modern list in Microsoft Lists. I’ll also cover Power BI and Planner.

Here’s the shortest path for the classic version:

Settings (gear) > Add an app > Tasks > Name > Create
LIST tab > Create View > Gantt View
Gantt Columns: Title = Task Name, Start Date = Start Date, Due Date = Due Date > OK

You get a task grid on the left and a timeline with one bar per task on the right.

What Is a Gantt Chart View in SharePoint?

A Gantt chart shows each task as a bar on a calendar: it starts on the start date, ends on the due date, and fills in as work gets done.

In SharePoint, it’s just another type of SharePoint list view, so your data doesn’t change. Only classic Tasks lists have a real Gantt View; modern lists need JSON.

Method 1: Create a Gantt Chart View Using a SharePoint Tasks List

This built-in way still works in SharePoint Online in October 2026. I built it on our SPGuides demo site for a website launch. More list basics are in our SharePoint tutorials.

Step 1: Add a Tasks list and tasks

Select the gear icon > Add an app. On the Your Apps page, pick Tasks under Noteworthy, enter a name and select Create:

The list already has Task Name, Start Date, Due Date, % Complete and Predecessors, plus a ready-made Gantt Chart view. I added 8 tasks from 11/2/2026 to 12/14/2026 and set Predecessors, so Go live waits on testing and training.

Step 2: Create the Gantt View

The Tasks list opens in the classic UI. Select the LIST tab, then Create View:

On the View Type page, choose Gantt View:

Enter a View Name (mine is Launch Timeline) and keep it a Public view:

Step 3: Map the Gantt columns

In Gantt Columns, Title, Start Date and Due Date are required; Percent Complete (the darker fill) and Predecessors (the arrows) are optional. I mapped each to the column of the same name:

Under Sort, pick Start Date, then select OK. Here’s the result on our demo site:

The chart shows weeks from 11/1/2026 to 12/13/2026, a darker fill for % complete and arrows to each predecessor. To change the mapping later, use LIST > Modify View.

Method 2: Build a Gantt Chart in a Modern List With JSON

In a modern list, the Create view dialog offers only List, Calendar, Gallery and Board:

So the Gantt look comes from view formatting, in the same menu you’d use for a board view in a SharePoint list.

Step 1: Create the list and view

I created a Website Launch Plan list in Microsoft Lists with Title, Start Date and End Date (date only, required), Progress (number as a percentage) and Status. Then I made a view sorted by Start Date and picked Format current view:

Step 2: Paste the JSON

On the Format view tab, select Advanced mode and replace the editor’s contents with this JSON:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/row-formatting.schema.json",
  "hideSelection": false,
  "hideColumnHeader": true,
  "rowFormatter": {
    "elmType": "div",
    "style": {
      "display": "flex",
      "align-items": "center",
      "width": "100%",
      "padding": "6px 0",
      "border-bottom": "1px solid #edebe9"
    },
    "children": [
      {
        "elmType": "div",
        "txtContent": "[$Title]",
        "style": { "width": "210px", "padding-left": "8px", "font-weight": "600" }
      },
      {
        "elmType": "div",
        "txtContent": "=toLocaleDateString([$StartDate]) + ' - ' + toLocaleDateString([$EndDate])",
        "style": { "width": "180px", "font-size": "12px", "color": "#605e5c" }
      },
      {
        "elmType": "div",
        "style": { "position": "relative", "flex-grow": "1", "height": "22px", "background-color": "#f3f2f1" },
        "children": [
          {
            "elmType": "div",
            "attributes": { "title": "=[$Title] + ': ' + ([$Progress] * 100) + '% complete'" },
            "style": {
              "position": "absolute",
              "top": "3px",
              "height": "16px",
              "border-radius": "3px",
              "background-color": "#a6d8db",
              "left": "=((Number([$StartDate]) - Number(Date('2026-11-01T00:00:00Z'))) / 86400000) * 2 + '%'",
              "width": "=(((Number([$EndDate]) - Number([$StartDate])) / 86400000) + 1) * 2 + '%'"
            },
            "children": [
              {
                "elmType": "div",
                "style": {
                  "height": "100%",
                  "border-radius": "3px",
                  "background-color": "#038387",
                  "width": "=([$Progress] * 100) + '%'"
                }
              }
            ]
          }
        ]
      }
    ]
  }
}

Select Preview, then Save. My panel before saving:

Each row now shows the task name, its dates and a bar on the timeline:

The light teal bar is the duration, and the darker part is progress. Unlike the classic view, there are no dependency arrows.

How to Change the Dates in the Gantt JSON

left counts the days from 11/1/2026 to the task’s start and multiplies by 2%. width is the task’s length in days plus one, times 2%. My window is 50 days, and 100 / 50 = 2.

For your project, replace 2026-11-01 with your start date and both 2 multipliers with 100 divided by your window’s days (90 days = 1.11).

Use internal column names. The same rules apply to calendar view formatting and list form JSON formatting.

Can You Make a Gantt Chart From a SharePoint List in Power BI?

Yes, when a manager wants a report rather than a list view. In Power BI Desktop, select Get data > SharePoint Online list and paste the site URL, not the list URL.

Load the list, add a Gantt visual from AppSource (Get more visuals), and map the task, start date and duration. See how to create a report in Power BI Desktop; edits still happen in SharePoint.

Which Gantt Chart Method Should You Use?

Need	Best option
Built-in Gantt with dependency arrows	Classic Tasks list + Gantt View
Modern list or Microsoft Lists	JSON view formatting
Management report	Power BI Gantt visual
Drag-to-reschedule, all dependency types, critical path	Planner premium plan (Timeline view)

I still reach for the classic Gantt View first. The JSON view suits teams that live in Microsoft Lists and only need a visual timeline.

SharePoint Gantt View Problems and Fixes

Gantt View isn’t offered

It only appears for a Tasks list in the classic LIST > Create View page. Custom and modern lists don’t get it; use the JSON method there.

A task shows no bar

Its Start Date or Due Date is empty. Make both date columns required so every task can be drawn.

JSON bars run off screen

The task falls outside your window. Move the start date in the JSON or lower the multiplier to cover more days.
