GridCraft — Spreadsheets
ArtCraft
GridCraft is a desktop spreadsheet app with ribbon tabs, a formula bar, more than 500 calculation functions, dynamic arrays, seventeen chart types and PivotTables. It reads and writes spreadsheet files (.xlsx) and also works with CSV and TSV files. It is free and open source under MIT or Apache-2.0 with no subscription, but its README calls it alpha and says depth, fidelity and file compatibility are still rough. The official getartcraft.com page lists GridCraft as “In development” (checked 13 October 2026).
