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.

About

ModelMonkey is an AI-powered spreadsheet assistant that integrates directly into Google Sheets and Microsoft Excel to help you analyze data, write and update formulas, build financial models, clean and automate workflows, and generate insights without manual formula writing or coding. You interact with your spreadsheet using plain-English commands while ModelMonkey reads your sheet’s structure, understands relationships and data flow, plans changes, shows what it will do for review, and then applies edits with explanations and one-click undo, avoiding black-box automation. It is powered by Claude Sonnet 4.5 and supports tasks like complex financial modeling (three-statement models, DCFs), trend analysis, data cleaning, integration with external data sources (including PostgreSQL), and dynamic formula generation, all with enterprise-grade encryption and zero data retention.
