Select Cells Like in a Spreadsheet

Overview

Select table cells like Excel and see the sum/average/count.

Select Cells Like in a Spreadsheet lets you select multiple cells in HTML tables on any website and instantly calculate values such as sum, average, and count — directly in your browser. The extension works entirely locally and does not collect, store, or transmit any personal or browsing data. Key features: • Spreadsheet-style multi-cell selection • Automatic calculation of sum, average, and count • Works on most websites with HTML tables • Lightweight and fast • No accounts, no tracking, no ads Permissions explanation: Access to web pages is required to detect and interact with HTML tables so users can select cells and calculate values. The storage permission is used only to save user preferences locally. Source code: https://github.com/komarove/selection-like-in-spreadsheet
