What we tried, and what happened

In the browser build (0.6.1, Oct 14, 2026)

✓Typed a value into A1 and pressed Enter; the Name Box moved to A2 and the title bar picked up an unsaved marker (Book1, then Book1 — Edited).
✓Opened the File start page and found four ready-made samples — Blank workbook, Household Budget, Quarterly Sales Dashboard and Gradebook — beside Save, Save As, Print and Export.
◐Ctrl+S did not produce a workbook here: the console in our headless run says Save file dialog cancelled by user, which is what a headless browser does when a page asks for a save location. We cannot tell from that whether saving works in a normal browser, and we are not calling it broken.

On a Mac (0.6.1, Oct 14, 2026)

✓Typed =SUM(1,2,3) into D6, pressed Enter, and the cell evaluated to 6 — a real calculation, not a stored string.
◐⌘S did nothing in our session, and we haven't finished a desktop save/export test yet.

What ArtCraft says it can do

From the GridCraft README — these are ArtCraft's claims, not our test results:

Familiar. “Excel's ribbon, formula bar, Name Box, sheet tabs, keyboard shortcuts, fill handle, point-mode formula entry with coloured references, Format Cells, Paste Special, conditional formatting, tables, charts and more. If you know Excel, you already know GridCraft.” We used the grid, the Name Box and the formula bar; the rest is untested by us.
Compatible. “XLSX is the native format”: styles, formulas including dynamic arrays, tables, conditional formats, charts, sparklines, PivotTables and print settings round-trip. Untested by us — we never had a real workbook in it.
Capable. Dynamic arrays and spilling, “500+ worksheet functions plus LET, LAMBDA, MAP, REDUCE…”, sort, AutoFilter and Flash Fill. We ran one three-argument SUM.
Fast. Copy-on-write workbooks, incremental recalculation and a virtualised grid that only lays out what is on screen. Our workbook had two cell values in it.

If you're coming from Excel

Excel habits we saw

You want to…	In Excel	In GridCraft (as we saw it)
Type into a cell	Click the cell and type, Enter to commit	Identical; Enter moved the selection to the cell below
Do arithmetic	`=SUM(…)` in the formula bar	Same syntax in the same bar — our `=SUM(1,2,3)` returned 6
See which cell you are on	Name Box, top left	Name Box in the same corner, reading A2 after our Enter
Format numbers and alignment	Home tab: Font, Alignment, Number groups	Home tab with the same groups and order

Every row above is something we did ourselves. Tell us at contact@artcrafttutorial.com if a row behaves differently on your machine.

What we haven't tested yet

Real workbooks. We have typed two values into a blank sheet and nothing else — no import of an .xlsx of ours, and no save that came back to us.
Charts, PivotTables and conditional formatting, which the README's screenshots lean on.
Formulas beyond SUM, including the dynamic-array functions and LET and LAMBDA.
