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

Melder is an AI-powered Excel add‑in that brings generative intelligence directly into spreadsheets, enabling users to upload documents and web data, then interact with them using intuitive AI formulas, all without leaving Excel. You can drop PDFs or other files into cells and use formulas to summarize, extract, classify, and analyze content; all outputs include clickable citations to source sentences for verification. Additionally, a sidebar chat assistant lets users ask questions or build workflows directly within the workbook. Melder excels at automating laborious tasks like extracting insights from data rooms, reviewing contracts by pinpointing key terms, streamlining market research through competitor website scraping, and synthesizing transcripts from interviews or calls, all with the power of Excel formulas and without switching tools.
