Smartsheet is a cloud-based platform that combines the familiarity of a spreadsheet with automation, project tracking, resource management, and dashboards. Founded in 2005 and publicly traded, it is particularly powerful for organizations that live in Excel but need collaboration and workflows that spreadsheets cannot provide. Its Grid, Gantt, Card, and Calendar views serve different working styles, while its automation engine handles notifications, approvals, and data routing without code — making it the preferred task and project management tool for operations-heavy teams.
