GridCraft, ArtCraft's spreadsheet app

GridCraft in the Crafting Apps lineup

The official Crafting Apps listing describes GridCraft as a spreadsheet and data tool and labels it In development. Its README introduces it with this line:

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

Opening workbook files in GridCraft

The README’s compatibility summary distinguishes native workbooks from imports with a narrower scope. Keep original files and check the result with your own workbooks.

GridCraft’s spreadsheet controls

The README’s “Familiar” bullet lists GridCraft’s ribbon, formula bar, Name Box, sheet tabs and keyboard shortcuts. It also documents a fill handle, formula entry with colored references, Format Cells, Paste Special, conditional formatting, tables and charts.

These are GridCraft’s documented interface elements. They do not establish complete workflow coverage; the README notes that full keyboard navigation and other ribbon access keys still need work. Source: familiar controls · Source: access-key limits.

How complete is GridCraft?

The project’s own README roadmap calls GridCraft an alpha and says depth, fidelity and file compatibility remain rough. Its figures are project estimates, rather than measurements by this guide:

• 89% of standard ribbon commands in the project’s catalog are covered.
• The worksheet-function figure is 513. The README now clarifies that this is a parity inventory, not a count of working implementations.
• Its weighted estimate is about 50% ready for real work, based on what spreadsheet users rely on.

The project’s next-up list is:

• XLSX fidelity with real-world files.
• Very large workbooks and multi-threaded recalculation.
• Greater chart depth.
• Text coverage in every script.
• Further .xls import work.

Limited .xls import is already documented; its presence on the roadmap does not imply full formatting or object support. These figures describe GridCraft’s own roadmap and do not establish finished workflow coverage.

GridCraft CLI and MCP automation

The README describes a headless MCP server, a bridge to a running window and a command-line tool for formulas, workbook commands and reading ranges. A JSON control channel adds pointer and keyboard input, dialogs and screenshots. The following block is copied verbatim from the official automation section:

claude mcp add gridcraft -- gridcraft-cli mcp                 # headless MCP server
gridcraft-cli mcp --connect 7979                               # MCP bridged to a running window
gridcraft-cli eval '=XLOOKUP("b",{"a","b"},{1,2})'             # → 2
gridcraft-cli run --sample budget --cmd 'home.bold={"range":"B4:F4"}' --out budget.xlsx
gridcraft-cli cat budget.xlsx --range B4:F15                   # aligned text table
gridcraft-cli commands --search chart                          # every command and its params

Naming difference in the snapshot: repository metadata points to /apps; the README points to /apps/gridcraft. We retain both official URLs without assuming why they differ.

The latest snapshotted release is v0.14.2, published 2026-10-31. These are exact asset names from that release; download them on the official Releases page.
