EmbedTable Catcher in-browser table extractor

One-click extraction of table data trapped inside iframes, virtual lists, and Canvas

Problem

Everyday work is full of data locked in iframes, paginated lists, virtual scrolling, or Canvas-rendered tables. Copy-paste fails and writing a scraper is overkill. A developer already shipped a Chrome extension covering iframes, pagination, and some Canvas cases, confirming this is a real, frequent pain.

Solution

A browser extension that auto-detects tables, iframes, and virtual lists on a page, with preview, column selection, and export to CSV, TSV, JSON, or XLSX, all processed locally with no upload. Add dedicated adapters for known heavy cases like Feishu sheets.

Users

Operations staff, analysts, finance, and office users who need to pull data out of internal admin systems

MVP

Detect plain HTML tables and tables inside iframes; crawl paginated and virtual lists incrementally; export CSV, TSV, JSON, and XLSX; fully local processing with no upload; dedicated adapters for one or two high-frequency sites

Revenue

Free basic tier plus paid advanced features (Canvas support, batch export, scheduled scraping); or a one-time purchase

Why now

Enterprise backends increasingly render tables with Canvas and virtual lists where copy and scraping both fail, and browser extensions are a form factor an indie dev can ship and polish quickly
