What Lattice does
400+ functions
A real formula engine (HyperFormula) with the math, lookup, date, text, financial, and statistical functions you actually use.
Multi-sheet workbooks
Add, rename, color, reorder, and duplicate sheets in one workbook — like Excel tabs, but cleaner.
Real formatting
Bold, italic, color, fill, borders, alignment, wrap, merge cells, plus number, currency, percent, and date formats.
Excel-compatible paste
Copy from Excel or Google Sheets and paste straight in. Copy back out and it lands cleanly in either.
Undo that means it
Every value, format, and structural change is undoable. Cmd/Ctrl-Z all the way back.
Local-first
Workbooks autosave to your device. Cloud sync lands when accounts come online.
Lattice is free. Open it.
No signup wall, no trial timer. Use it for as long as you need it.
