A Gantt chart in Google Sheets is a timeline view that allows users to create a visual representation of their tasks and projects over time. This feature has been added to Google Sheets through its switch to canvas-based rendering, providing a new way to view spreadsheet data chronologically. The Gantt chart can be customized with settings such as grouping by another column, changing the view to look at it by day, week, month, quarter, year, or just what's up for today, and adding details to cards. This feature is useful for project managers, but also has potential applications in to-do lists and dashboards, offering a visualization of time that can help users track progress and stay organized. The Gantt chart integrates well with other Google apps, including Zapier, making it easy to pull in data from existing spreadsheets or other apps and jump straight into a usable timeline. While it may not replace other apps that specialize in Gantt charts, such as ClickUp or monday.com, it is a valuable addition to the Google Sheets toolset.
