Spreadsheet

Spreadsheet gives you everything you expect from a modern spreadsheet, plus an AI assistant that works right beside your data. A powerful alternative to Microsoft Excel and Google Sheets, ask it to add a totals row, build a chart, sort a list, or explain what a formula does. It reads your sheet, makes the change, and shows each step it took, so you always know what changed. One click undoes a whole reply.

When you would rather do it yourself, the tools are ready. Over 500 functions cover math, statistics, lookups, dates, text, and finance, with autocomplete and plain-language hints as you type. Turn any range into a column, line, donut, or combo chart, then format your sheet with tables, filters, conditional formatting, and dropdowns.

Your files stay yours. Every spreadsheet saves automatically as a standard .xlsx file in your own Puter cloud, ready to open in Excel, Numbers, or LibreOffice. Version history keeps earlier snapshots, and unsaved edits are kept on your device if your connection drops.

Spreadsheet opens straight into a new sheet, with no sign-in needed to start. It works on desktop, tablet, and phone, in light or dark mode.
