Everything a spreadsheet should do — together
Every feature below runs on the same grid, in real time, for every collaborator.
Real formulas, server-side
SUM, VLOOKUP, IF, date math and more — computed authoritatively on the server, not just in your browser tab.
Real-time co-editing
See who's viewing, watch edits appear live, and never lose work to a conflicting save — cell-level locking keeps everyone in sync.
Formatting that means something
Bold, colors, and number formats cascade from sheet → column → row → cell, so a whole column can be styled once and stay consistent.
Built-in data validation
Constrain a column to a fixed list of values — a real dropdown, enforced server-side, not just a suggestion.
Excel in, Excel out
Import existing .xlsx workbooks and export back to Excel, CSV, or JSON whenever you need to hand data off.
Granular sharing controls
Invite people at exactly the level they need — read-only, edit, or full ownership — down to a single workbook.
