- A spreadsheet program with a ribbon menu, formula bar, sheet tabs and shortcuts like Excel. The ArtCraft team created it, and the original says users familiar with Excel can use it comfortably.
- It opens and saves XLSX files, the default Excel format, and the original says formatting, formulas, charts and pivot tables are kept after saving. Older .xls files open only values, formulas and number formats, and formatting and objects are not yet supported.
- The project says it is in alpha. The development team wrote that it has implemented 89% of the Excel ribbon commands and 513 of the 523 worksheet functions. The judgment that practical readiness is about 50% is the team's own estimate.
- Installers for macOS, Windows, Linux and FreeBSD, and a web browser version, are posted on GitHub releases. The development team claims there is no subscription fee, no license server and no usage data collection.
O: A self-employed person who uses several Excel files could open a copy of one household budget file in GridCraft and check whether the formatting, formulas, and charts still appear as they should.
X: The original text says this is an alpha stage and that older .xls files do not yet support formatting and objects, so the original files must be kept separately.
