What it does
GridCraft is a desktop spreadsheet program laid out like Excel, with a ribbon, formula bar, over 500 functions, tables, conditional formatting, 17 chart types, pivot tables and PDF export. Its main file format is .xlsx, and it can also read CSV and older .xls files. AI agents can control it through a command-line tool. The project is less than three weeks old, and its README calls it alpha and estimates it is about 50% ready for real work. Windows has ready .msi installers and portable .zip files.

AI review
- Inforeadme lists files not in releases
README.md lists gridcraft-<ver>-freebsd-x86_64.tar.gz and gridcraft-web-<ver>.zip builds, but neither file appears in the v0.10.0, v0.11.1 or v0.12.1 release file lists.
AI review
Evidence is shown in its original language.
What Radar could not check
- How faithfully real-world Excel files with complex formatting, macros or charts open and save, given the README's alpha status
- How it copes with very large workbooks, which the README lists as future work
- Whether the Windows installers are really code-signed, as the README states
- What the built-in update check (craft-update library) connects to, given the README's claim of no telemetry
- Whether the very fast growth in stars and forks reflects real use
