How To Export Gantt Chart Data To Excel And CSV Formats

Updated on Apr 21, 2026

The Blazor Gantt Chart is a powerful project planning and management component that provides a Microsoft Project–like interface for visualizing and managing hierarchical tasks along a timeline. It enables users to plan, track, and manage project schedules efficiently by representing tasks, dependencies, milestones, and progress in a structured and interactive format.

This repository contains a quick-start sample that demonstrates how to export Gantt Chart data to Excel and CSV formats in a Blazor Web Application. Exporting Gantt Chart data allows to share project information with stakeholders, perform offline analysis, archive schedules, and integrate project data with external tools such as Microsoft Excel and other spreadsheet applications.

This sample demonstrates how to configure export functionality, invoke export actions programmatically, and generate downloadable files that preserve the task hierarchy and scheduling information displayed in the Gantt Chart.
