This short article guides on how to create Gantt chart in Excel using Python. It has details to set the IDE, a list of steps, and a sample code to generate Gantt chart in Excel. You will get complete details and sample data to create a Gantt chart without the need for any external data source.

Steps to Construct a Gantt Chart using Python

1. Set the environment to use Aspose.Cells for Python via .NET to create a Gantt chart
2. Load the Aspose.Cells license and create a new Workbook with a sheet with a given name
3. Define tasks with specified start/end dates and add a header row for the table
4. Select the earliest date from the tasks list as a baseline for all timeline offsets
5. Calculate the offset and time span in days for each task and insert those values into the sheet
6. For better visualization, set the date format and auto-fit relevant columns in the sheet
7. Create cell ranges for labels, offsets and spans, then add a stacked bar chart in the sheet
8. Customize the chart by hiding the offset series, styling the span series and setting other parameters
9. Save the workbook on the disk

These steps summarize the process for a Gantt chart maker using Python. Start the workflow by creating a Workbook, loading a license, defining tasks with dates, and calculating a timeline for each task based on the earliest start date. Finally, format the sheet for clarity, build and configure the stacked bar chart for clarity and customize it to visualize the schedule before saving it on the disk.
