Gantt Chart Maker & Timeline Project Planner - 2026 Pricing, Features, Reviews & Alternatives

Gantt Chart Maker (Timeline Task Planner) by Uniform Software is a high-performance Windows COM add-in that integrates an automated project scheduling engine directly into Microsoft Excel. Designed for project managers, engineers, consultants, and operations directors, the application bridges the gap between static spreadsheet task lists and complex standalone project management suites. Available through the Microsoft Store and Microsoft Marketplace, it provides corporate teams with a frictionless procurement path and seamless desktop deployment.

Rather than relying on fragile grid formulas or manual shape formatting, Gantt Chart Maker connects worksheet rows directly to an automated calculation and visualization engine. Users simply enter task titles, start dates, and durations to generate professional Gantt charts with milestones, summary task groupings, auto-updating WBS numbering, and progress indicators.

The add-in includes an advanced task dependency engine supporting all four standard link types: Finish-to-Start (FS), Start-to-Start (SS), Finish-to-Finish (FF), and Start-to-Finish (SF). When an upstream project activity experiences a delay, schedule adjustments cascade downstream automatically across connected tasks based on user-defined lag or lead times.

To reflect real-world project constraints, Gantt Chart Maker features configurable resource and holiday calendars. Teams can map non-working days, custom weekend shifts, and regional corporate holidays into duration formulas, ensuring net duration calculations accurately skip non-working periods. Additionally, integrated baseline tracking allows project leads to lock initial target plans and overlay them against active project progress to visually identify schedule variance and scope creep.

Gantt Chart Maker offers multi-scale timeline controls, allowing users to toggle visual views across Daily, Weekly, Monthly, Quarterly, Half-Yearly, and Yearly perspectives with standard ISO week numbering. High-resolution vector diagrams and formatted schedules can be exported directly to PDF using native Excel export capabilities.

Engineered with a privacy-first architecture, 100% of project data remains stored in standard .xlsx workbooks and local or network-mapped Microsoft Access databases (.accdb). By operating strictly within the local desktop environment without external cloud server transmission, Gantt Chart Maker ensures total data ownership and meets stringent enterprise IT compliance requirements.
