SuperTables

Browser extension for enhancing tables in webpages

🚀 SuperTables — Explore, Filter & Export Any Table on Any Page SuperTables turns the raw tables on any website into an interactive workspace — filter rows, sort columns, chart data, and export exactly what you need, without ever leaving the page or opening a spreadsheet. Works on HTML tables, ARIA grids, and complex visual layouts alike. Everything runs entirely in your browser; no data ever leaves your device. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ✨ CORE FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔍 Smart Table Detection • Detects HTML tables, ARIA grids/treegrids, shadow-DOM tables, and visual "table-like" layouts • Cycle through every detected region with Prev / Next — each is highlighted on the page • Picker mode: click a crosshair directly onto any table-like region to grab it instantly • Live row and column count updates as you navigate or filter • Automatically hides repeated header rows in paginated single-page tables so duplicates never clutter your view 🧪 Powerful Filtering — Right on the Page A filter row drops in directly under the table header. Filter every column independently, in real time: Numeric & range expressions <5 >=100 =42 BW(1,10) Set & substring filters IN(a,b,c) NOT IN(x,y) LIKE(foo,bar) Formula filters (new!) =ISNUMERIC(True/False) — keep only numeric / non-numeric cells =ISBLANK(True/False) / =ISEMPTY(True/False) — empty or non-empty cells =ISTEXT(True/False) — text-only or non-text cells =CONTAINS(text) / =STARTSWITH(text) / =ENDSWITH(text) — string tests LEN>5 LEN<=10 — filter by cell text length !expression — negate any filter above Pattern matching Anything else is treated as a case-insensitive regular expression • Click the ℹ️ info icon in the filter row for an always-handy syntax reference • After filtering, the page smoothly scrolls the filter row back into view 📌 Pinned Filters — Auto-Restore on Every Visit • Click Pin Filters on any table to save the current filter set for that URL • Filters are re-applied automatically the next time you visit the page • If you adjust filters on a pinned page, a 🔄 Update Pin button appears — one click saves the new filters as the pinned set • Manage all pinned pages from the Saved Filters tab in the popup 💾 Stored Tables — Your Personal Table Archive • Save any table view (with its filters, sort, and hidden columns) inside the extension • Reopen the source URL from the stored-tables list and the saved view is automatically restored • Open stored tables in a standalone viewer tab — even works on restricted pages • Rename, copy, export, or delete any stored entry • Back up all stored tables and pinned filters to a single JSON file; restore them anytime • Search and sort the stored-tables list 📊 Instant Data Insights • Column stats: sum, average, median, mode — computed on visible (filtered) rows • Column charts: compare up to 4 columns side-by-side with Bar, Line, or Area charts • Inspect any individual row in a full-detail modal 🧘 Zen Mode — Full-Screen Table Workspace • Opens the table in a distraction-free overlay right inside the page • Filter (with the full formula engine above), sort, hide columns, and inspect rows • Inline cell editing — edit any cell value and export the modified data • Drag column borders to resize; click headers to sort 📤 Flexible Export • Export to CSV, Markdown table, or JSON • Copy to clipboard (tab-delimited — pastes directly into Excel or Google Sheets) • Pick exactly which columns to include • Choose filtered rows only, or the full table ⌨️ Keyboard Shortcuts On the page (global): Alt + Shift + N — Next table Alt + Shift + P — Previous table Alt + Shift + S — Select table Alt + Shift + E — Export CSV Alt + Shift + G — Picker mode Alt + Shift + Z — Open Zen Mode Alt + Shift + L — Store table locally Esc — Close overlay Inside the popup: Alt + 1 — Stored Tables tab Alt + 2 — Saved Filters tab Alt + 3 — Features tab Alt + 4 — Syntax reference tab Alt + 5 — Shortcuts tab ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🧠 WHO IS IT FOR? ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Analysts & researchers — filter live data tables without exporting, archive snapshots, track changes Finance & investing — screen stocks, slice financial tables, pin your favourite filters Developers — inspect and export data from API response tables, admin UIs, or documentation pages Students — pull structured data from research portals without manual copy-paste Anyone who has ever opened a spreadsheet just to sort or filter a table they found online ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRIVACY FIRST ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ SuperTables works entirely offline. No analytics, no telemetry, no external servers. Your table data, stored tables, and pinned filters live only on your device, in Chrome's local extension storage. 🏁 Explore. Filter. Analyze. Export. All without leaving the page.
