About

Gantt Chart Maker (Timeline Task Planner) is a Windows Excel-based app that integrates an automated project scheduling engine directly into Microsoft Excel. Engineered with a privacy-first local architecture, all project data remains inside standard .xlsx workbooks. Microsoft Marketplace Availability: Licensing via the Microsoft Store and Microsoft Marketplace. Trial avaiable. 4-Type Dependency Support: Full support for FS, SS, FF, and SF task connections with automatic forward-pass delay cascading. Baseline & Variance Analysis: Overlays locked target estimates against active progress to track scope creep and schedule deviations. Resource & Holiday Calendars: Maps custom work schedules, rest days, and regional holiday lists to skip non-working periods. Multi-Scale Timeline Views: Toggles calendar grids across Daily, Weekly, Monthly, Quarterly, Half-Yearly, and Yearly views with ISO week numbering.

About

GridCraft is an open-source spreadsheet application for creating, editing, calculating, and analyzing workbooks on desktop or in a browser. Its interface includes a ribbon, formula bar, and sheet tabs, with tools for formulas, dynamic arrays, tables, sorting, filtering, data validation, conditional formatting, charts, and PivotTables. It supports XLSX, CSV, and TSV workbooks, with comments, hyperlinks, print settings, and PDF output. Users can build budgets, schedules, sales summaries, and other data tables, then calculate and visualize results in a workbook. Desktop releases are available for Windows, macOS, and Linux; a WebAssembly build can be hosted on a static server. A command-line tool, JSON control channel, and Model Context Protocol server let developers and AI agents inspect, edit, calculate, and format workbooks programmatically. GridCraft is free, open-source software, and its maintainers currently describe the project as pre-alpha.
