GridGrab — Table & Card Exporter

Preview visible tables and repeating cards, then export selected columns to safe CSV or TSV.

GridGrab turns visible page tables and repeating card lists into a dataset you can review before exporting. Choose whether to scan the whole page DOM or the area around a current text selection. GridGrab detects usable HTML tables and consistent repeating-card groups, then opens a compact preview in Chrome's side panel. Pick the dataset, include all currently loaded rows or only rows visible during the scan, and uncheck columns you do not need. Features: - Detects visible HTML tables and repeating card groups already present on the page - Keeps merged `rowspan` and `colspan` cells aligned in a rectangular export - Handles multi-row headers and duplicate column names - Previews the first 50 selected rows before export - Downloads CSV or copies tab-separated text for spreadsheet paste - Escapes commas, tabs, quotes, and line breaks - Neutralizes formula-like cell values before spreadsheet export - Runs only when you press Scan and processes data locally - Uses temporary access to the selected tab, with no broad host permission GridGrab takes a bounded snapshot of content already in the current page DOM. It does not paginate, auto-scroll, monitor page changes, access hidden pages, bypass restrictions, or export XLS/XLSX. Rescan after a dynamic page loads new content. Use GridGrab only on pages and data you are allowed to access and export.
