Description

Gantt Chart Maker (Timeline Task Planner) is a native Windows Excel-based app that transforms Microsoft Excel into an offline project scheduling engine. Built for engineers, developers, and technical project leads who require deterministic schedule calculations without sending sensitive project data to third-party web servers, the software executes entirely within the local desktop environment. Instead of relying on fragile grid formulas or web wrappers, the add-in hooks directly into Excel’s native architecture. It processes task lists into dynamic Gantt charts with automated dependency cascading across four standard link types: Finish-to-Start (FS), Start-to-Start (SS), Finish-to-Finish (FF), and Start-to-Finish (SF). An internal calculation module accounts for custom working schedules, non-working days, and corporate holiday lists to compute accurate net durations across complex task networks. Key technical capabilities include baseline locking for schedule variance analysis, multi-scale timeline grids (Daily to Yearly with ISO week numbering), and high-density vector PDF rendering via Excel’s native print engine. Data persistence relies strictly on standard .xlsx workbooks and local or network-mapped Microsoft Access (.accdb) databases, ensuring zero network transport of confidential project metadata. Available via the Microsoft Store and the Microsoft Marketplace, Gantt Chart Maker provides a lightweight, and enterprise-deployable scheduling tool for Windows 10 and 11 environments.

Description

GanttTool is a fully free, privacy-first Gantt chart generator designed for simple yet powerful project management. Built entirely in the browser, it stores all data locally through autosave, meaning no accounts, tracking, or server uploads are ever required. The platform leverages PlantUML to render elegant, professional diagrams that can be exported as SVG, PNG, or raw code for use in documentation. Users can define detailed tasks, dependencies, milestones, and project phases, with intelligent validation to prevent circular relationships. A flexible scheduling engine supports date-based timelines, offset-based planning, and dynamic dependency handling. Additional features include drag-and-drop task handling, custom colors and fonts, resource allocation indicators, and non-working days like weekends or holidays. Projects can be saved or loaded as JSON, allowing easy backup and sharing. Rated highly by project managers, GanttTool delivers advanced planning capabilities without cost or complexity.
