GridCraft

GridCraft is an open-source, native spreadsheet for calculating, analysing and charting data in workbooks, with support for Excel (XLSX) and CSV files.

GridCraft is part of the open-source ArtCraft "Crafting Apps": a native Rust
application that runs locally on your own files and can be driven from a CLI,
a JSON control channel or an MCP server.

This snap repackages the official upstream Linux release. The headless
command line tool is available as gridcraft.cli.
