Need a quick budget, task list or project plan without opening Excel or Google Sheets? Tentaco Spreadsheet Studio is a full workbook editor that runs entirely in your browser tab.

Create cells, use formulas (SUM, IF, AVERAGE and more), format numbers and text, manage multiple sheets, import CSV or exported JSON workbooks, and export results when you are done. Workbooks autosave to IndexedDB on your device — nothing is uploaded to our servers by default.

Optional encrypted device sync lets you continue the same workbooks on another laptop or phone with your recovery key. Free, no account required.
