GridCraft（GitHub：https://github.com/storytold/gridcraft ，2026-10-07 创建，今晨抓取时已 6,881★）是 ArtCraft 团队用纯 Rust 从零写的开源电子表格：界面、操作和文件格式都向 Excel 看齐，XLSX 就是它的原生格式，macOS、Windows、Linux、BSD 和浏览器（WebAssembly）都能跑，无订阅、无授权服务器、无遥测。

它有 500+ 工作表函数（含 LET、LAMBDA、动态数组和结构化表引用）、透视表、17 种图表、条件格式、迷你图和打印预览；老 .xls 文件能打开数值、公式和数字格式，XLSB、ODS 的数据也能导入。最有意思的一点是“Agent 原生”：每一个功能区按钮、菜单、对话框、按键和鼠标手势都是一条命令，Agent 可以通过 JSON 控制通道、MCP 服务器或命令行直接驱动它——比如 gridcraft-cli eval '=XLOOKUP("b",{"a","b"},{1,2})' 就能直接算出结果。项目目前自认处于 alpha 阶段，核心流程已跑通，但文件保真度和大工作簿性能还在打磨。

为什么值得了解

• 对受够了订阅制办公软件的人来说，这是一个真正免费、离线可用、文件格式还和 Excel 互通的替代品，浏览器版打开就能用
• 对开发者和 Agent 玩家更有意思：电子表格第一次变成“能被 Agent 编程操控”的对象，批量填表、做报表、跑公式都可以交给 Agent
• 它是 storytold 那套“纯 Rust 重写经典软件”系列的新成员（之前有 Word、CAD），同一团队、同一路数，感兴趣可以顺着这个系列一起看

English Version

GridCraft (GitHub: https://github.com/storytold/gridcraft , created 2026-10-07, 6,881 stars at this morning’s fetch) is an open-source spreadsheet written in pure Rust from scratch by the ArtCraft team: the interface, operations and file format all follow Excel, XLSX is its native format, and it runs on macOS, Windows, Linux, BSD and in the browser (WebAssembly) — no subscription, no licence server, no telemetry.

It ships 500+ worksheet functions (including LET, LAMBDA, dynamic arrays and structured table references), pivot tables, 17 chart types, conditional formatting, sparklines and print preview; legacy .xls files open with values, formulas and number formats, and XLSB and ODS data can be imported. The most interesting part is that it is “agent-native”: every ribbon button, menu item, dialog, keystroke and mouse gesture is a command an agent can run over a JSON control channel, an MCP server or the CLI — for example, gridcraft-cli eval '=XLOOKUP("b",{"a","b"},{1,2})' evaluates straight to a result. The project calls itself alpha: the core workflow works end to end, but file fidelity and very large workbook performance are still being polished.

Why it’s worth knowing

• For anyone tired of subscription office software, this is a genuinely free, offline-capable alternative whose file format still round-trips with Excel, with a web version you can open in the browser
• For developers and agent enthusiasts it is more interesting still: a spreadsheet becomes something an agent can drive programmatically — filling tables, building reports and running formulas can all be handed to an agent
• It is the newest member of storytold’s “classic software rewritten in pure Rust” series (Word and CAD came before it), from the same team and the same playbook, worth following as a series if it catches your eye
