Instant Sheet Highlighter

Keep your place in Google Sheets with private row and column highlighting. Select a cell with your mouse or keyboard. Highlight its row, its column, or both using independent switches in the toolbar popup. Choose a highlight color and strength. Existing row preferences are preserved when you update. - Follows the active cell as you move. - Separate Row and Column switches; turn either or both off. - Handles frozen panes and scrolling. - Leaves cell contents, formatting and undo history untouched. - The highlight stays local to your browser; collaborators do not see it. - No AI or analytics. Reads selection-outline geometry rather than spreadsheet cell values. Google Sheets is a trademark of Google LLC. Independently developed; not affiliated with or endorsed by Google.
