SelStats

Select numbers on any page for instant Count, Sum, Avg, Median, Min & Max. Alt/Option-click a table cell for column stats.

Instant statistics for table columns and selected ranges Need a total, an average, or a min and max from a table column — without retyping figures into a spreadsheet or a calculator? SelStats puts Count, Sum, Avg, Median, Min, and Max on the page, then lets you copy the ones you need. From column, to range, to copy 1. Column. Alt-click a table cell (Option-click on a Mac). SelStats computes statistics for that whole column. If you wanted the full column, you are done — one gesture. 2. Range. To tighten the total, hold Alt+Shift and click another cell in the same column (Option+Shift-click on a Mac). Stats cover those rows, inclusive. The pill can show a label such as Col Price rows 1–7: (data rows; headers are not counted). 3. Copy. Click the pill to copy. Sum and Avg are the defaults. In Options, choose any mix of Count, Sum, Avg, Median, Min, and Max, as one line (for example, Sum: 1,234 Avg: 176.3) or as tab-separated rows for a spreadsheet. You can also select numbers in page text; the pill appears when two or more numbers are selected. Header rows, heading cells, empty cells, and cells with no number are skipped. Only the first number in each cell counts. Column mode is documented for real HTML tables (including colspan and rowspan), ARIA grids such as those used on Yahoo Finance, and plain repeated row markup. Press Esc or make a new selection to clear the highlight. Worked examples The six examples below are constructed illustrations. Statistics were calculated independently to show the kind of answers SelStats is built to report — Count, Sum, Avg, Median, Min, and Max. They are not captured outputs from a live run of the extension. 1) Invoice amounts — whole column $1,250.00 · $875.50 · $2,100.00 · $430.25 · $990.00 Count 5 · Sum 5,645.75 · Avg 1,129.15 · Median 990.00 · Min 430.25 · Max 2,100.00 2) Product prices $14.50 · $22.00 · $18.75 · $31.25 · $9.50 · $27.00 · $17.00 Count 7 · Sum 140.00 · Avg 20.00 · Median 18.75 · Min 9.50 · Max 31.25 3) Package weights 2.4 · 1.8 · 3.5 · 2.1 · 2.7 Count 5 · Sum 12.5 · Avg 2.5 · Median 2.4 · Min 1.8 · Max 3.5 4) Unit sales — a contiguous range of five rows 42 · 38 · 35 · 31 · 28 Count 5 · Sum 174 · Avg 34.8 · Median 35 · Min 28 · Max 42 5) Stock on hand 70 · 80 · 200 · 50 · 150 · 90 · 130 Count 7 · Sum 770 · Avg 110 · Median 90 · Min 50 · Max 200 6) Credits and charges, including negatives 150.00 · −25.00 · 80.00 · −12.00 · 47.00 Count 5 · Sum 240.00 · Avg 48.00 · Median 47.00 · Min −25.00 · Max 150.00 SelStats is documented to read negatives, decimals, thousands separators such as 1,234.5, $ and €, percent signs, and accounting negatives such as (12) = −12. European forms like 1.234,5 are not supported. Quantified wins • One gesture instead of retyping a column. On a 25-row Amount column, one Alt-click (Option-click on a Mac) is documented to cover the whole column — not 25 figures typed into a calculator. Empty cells and cells without a number are skipped. • Illustrative 25-row column, independently totaled: Count 25 · Sum 3,750 · Avg 150 · Median 140 · Min 42 · Max 310. Same six outputs, with no manual re-entry of those 25 numbers. • Copy without retyping. Click the pill; Sum and Avg copy unless you choose otherwise. • A compact listed package: 23.02 KiB. One published select-to-sum alternative is listed at 31.54 KiB — 8.52 KiB, or 27.01%, smaller by listed size. Package size is not a speed or memory claim. SelStats is documented to use only the storage permission, for your options, with no network and no tracking. The Chrome Web Store listing states that the developer will not collect or use your data. It does not work on chrome:// or brave:// pages, the Chrome Web Store, or the browser’s built-in PDF viewer. Virtualized grids only include rows currently in the page. It is built for web pages and HTML or ARIA tables, not every surface a browser can open. Select a column. Tighten the range. Copy the stats. That is the job.
