About this extension
๐ SuperTables โ Explore, Filter & Export Any Table on Any Page
SuperTables turns the raw tables on any website into an interactive workspace โ 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.

โโโโโโโโโโโโโโโโโโโโโโโโโโโโโโ
๐ Smart Table Detection
โข Detects HTML tables, ARIA grids/treegrids, shadow-DOM tables, and visual "table-like" layouts
โข Cycle through every detected region with Prev / Next โ each is highlighted on the page
โข Picker mode: click a crosshair directly onto any table-like region to grab it instantly
โข Live row and column count updates as you navigate or filter
โข Automatically hides repeated header rows in paginated single-page tables so duplicates never clutter your view
๐งช Powerful Filtering โ 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) โ keep only numeric / non-numeric cells
=ISBLANK(True/False) / =ISEMPTY(True/False) โ empty or non-empty cells
=ISTEXT(True/False) โ text-only or non-text cells
=CONTAINS(text) / =STARTSWITH(text) / =ENDSWITH(text) โ string tests
LEN>5 LEN<=10 โ filter by cell text length
!expression โ negate any filter above
Pattern matching
Anything else is treated as a case-insensitive regular expression
โข Click the โน info icon in the filter row for an always-handy syntax reference
โข After filtering, the page smoothly scrolls the filter row back into view
๐ Pinned Filters โ Auto-Restore on Every Visit
โข Click Pin Filters on any table to save the current filter set for that URL
โข Filters are re-applied automatically the next time you visit the page

โข Rename, copy, export, or delete any stored entry
โข Back up all stored tables and pinned filters to a single JSON file; restore them anytime
โข Search and sort the stored-tables list
๐ Instant Data Insights
โข Column stats: sum, average, median, mode โ computed on visible (filtered) rows
โข Column charts: compare up to 4 columns side-by-side with Bar, Line, or Area charts
โข Inspect any individual row in a full-detail modal
๐ง Zen Mode โ Full-Screen Table Workspace
โข Opens the table in a distraction-free overlay right inside the page
โข Filter (with the full formula engine above), sort, hide columns, and inspect rows
โข Inline cell editing โ edit any cell value and export the modified data
โข Drag column borders to resize; click headers to sort
๐ค Flexible Export
