  Quarterly Sales Dashboard: a table with a totals row, conditional formatting, sparklines and two live charts — built entirely from GridCraft commands (File → New → Sample).

 A look around



Formatting. Accounting formats, cell styles, conditional rules and colour scales, frozen headers and a bar chart.
Formulas. 500+ functions, dynamic arrays, LET and LAMBDA, structured table references.


Dark mode and the Insert tab: tables, charts, sparklines, pictures, shapes, links and comments.
Pivot tables. Field list, filters, layouts, date grouping and show-values-as, saved to and read from XLSX.


Charts. Seventeen chart types, Chart Design tab and a Format pane; selecting a chart outlines its source data.
Page Break Preview, print settings, and PDF export and printing.



 Why GridCraft

- Familiar. 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. Everything is right where you expect it.
- Compatible. XLSX is the native format: styles, themes, formulas (including dynamic arrays),
  tables, conditional formats, validation, comments, hyperlinks, charts, pictures, sparklines,
  pivot tables and print settings round-trip. CSV and TSV too.
  Legacy 97-2003 .xls workbooks open with their values, formulas and number formats (formatting and objects not yet).
  XLSB worksheet data can be imported, using saved values instead of formulas.
  ODS worksheet data can be imported, using saved values instead of formulas.
  Static pictures can live inside cells, fitting their size and moving with the data.
- Capable. A dependency-graph calculation engine with dynamic arrays and spilling,
  500+ worksheet functions plus LET, LAMBDA, MAP, REDUCE, SCAN, BYROW, BYCOL and MAKEARRAY,
  structured table references, a comprehensive number-format language, sort and AutoFilter,
  Flash Fill, data validation, outlining and subtotals.
- Fast. Copy-on-write workbooks (undo snapshots are nearly free), incremental recalculation,
  and a virtualised grid that only lays out what's on screen.
- Agent-native. Every ribb
