Architecture

GridCraft is an engine-first Cargo workspace with enforced layering (cargo xtask layers). The egui frontend is a separate crate, so the UI can be swapped without touching the engine.

• L0 — core (addresses, values, errors, dates, input parsing) · numfmt (number format codes)
• L1 — formula (lexer, parser, printer, reference adjustment) · functions (worksheet function library)
• L2 — model (workbook, sheets, copy-on-write cells, styles, tables, charts…) · calc (dependency graph, evaluator, dynamic arrays) · xlsx (XLSX, CSV, plus XLSB and ODS data import)
• L3 — chart (toolkit-free chart layout and rendering)
• L5 — engine (session, commands, history, clipboard, fill, sort, filter, file I/O)
• L6 — ui-egui (spreadsheet UI, control channel) · mcp (MCP server)
• L7 — apps/gridcraft, apps/gridcraft-cli, apps/gridcraft-web
• Contributor and agent rules (clean-room, asset policy, never-crash, quality gates): AGENTS.md
• Bundled assets: each one is listed with its licence in ATTRIBUTION.md
• Releases: signed macOS, Windows, Linux, BSD and web builds; see docs/releasing.md

Ribbon access keys

Press and release left Alt on Windows/Linux/BSD, or press F10 on any platform, then type a sequence below one key at a time. Keytips appear on the supported Home controls and menu items. On macOS, use F10 (Fn+F10 if required by your keyboard); Option remains available for entering accented characters.

In Paste Special, T/V/F/C select formats/values/formulas/comments, and E toggles Transpose. Enter applies the selected options; Escape cancels the dialog. These letters also work with Alt held on Windows/Linux/BSD.

Escape backs out one keytip level; Alt/F10 again exits keytips. Clicking, scrolling, or switching windows cancels navigation. Access keys do not start while editing text or using another dialog. This is initial support for these Home and legacy paths; other ribbon commands and full mouse-free navigation remain to be implemented. Browsers or desktop environments may reserve Alt/F10 for their own menus.

• H A L / H A C / H A R — Align left / center / right
• H V S or legacy E S — Open Paste Special
• H O I or legacy O C A — AutoFit selected columns

概述

Spreadsheets and data; an open-source, high-performance modern spreadsheet application, built in pure Rust.

A fast, open-source, clean-room take on modern spreadsheet workflows. It runs natively on macOS, Windows, Linux and BSD, and in the browser via WebAssembly. By the ArtCraft team.

Quarterly Sales Dashboard: a table with a totals row, conditional formatting, sparklines and two live charts — built entirely from GridCraft commands (File → New → Sample).

A look around

Formatting. Accounting formats, cell styles, conditional rules and colour scales, frozen headers and a bar chart. Formulas. 500+ functions, dynamic arrays, LET and LAMBDA, structured table references. Dark mode and the Insert tab: tables, charts, sparklines, pictures, shapes, links and comments. Pivot tables. Field list, filters, layouts, date grouping and show-values-as, saved to and read from XLSX. Charts. Seventeen chart types, Chart Design tab and a Format pane; selecting a chart outlines its source data. Page Break Preview, print settings, and PDF export and printing.
