Tranquil Tables

A tiny, always-ready spreadsheet for back-of-the-envelope calculations.

A little spreadsheet, right beside what you’re doing. Comparing prices? Adding up a trip budget? Checking a few numbers while you work? Open Tranquil Tables in Chrome’s side panel and keep your calculations next to the page you’re using. It’s one small, persistent scratchpad: six columns, sixteen rows, and the essentials for everyday calculations. QUICK, FAMILIAR CALCULATIONS • Use +, −, × and ÷, parentheses, and cell references. • Add up a range with SUM or find its AVERAGE. • Click cells or drag across a range to insert references into a formula. • See referenced cells highlighted and results update automatically. • Type percentages directly or apply percentage formatting. EASY TO WORK WITH • Paste tab-separated data into multiple cells. • Copy a selection or all populated cells to use elsewhere. • Undo and redo edits, including clearing the sheet. • Enter numbers like 1.5k or 12m. Compact results stay readable, with the full value shown for the selected cell. READY WHEN YOU RETURN Your scratchpad saves automatically on your device. Close the panel and come back to your numbers later. No account, no network requests, and no cloud storage. Works offline. Tranquil Tables is designed for the small calculations that come up while browsing. One sheet, a fixed grid, and just enough spreadsheet to get the answer.
