Useful questions for a table

Compare stated conditions

Compare the rows using only the supplied values. Keep units and footnotes, cite the source page, and mark unavailable values rather than guessing.

Check a list

Identify duplicate entries and missing fields. Explain the rule used and leave the original values available for review.

FAQ

Is this the file-list CSV?

No. File-list CSV describes downloaded-file URLs and metadata. This workflow extracts supported HTML table data through the collector’s AI output.

Will every table become CSV?

Table export applies to meaningful HTML tables within extraction limits when per-page or full-package output is selected. Layout tables are excluded; images and PDF screenshots are not guaranteed table data.

Can I export XLSX directly?

This workflow produces CSV/JSON table files. Open or import CSV in Excel yourself; there is no direct XLSX export.

Can I start with Free?

Free collects one chosen page; Pro can select multiple page bodies. The extension prepares files locally. You pass them to Excel or an external AI tool yourself.

What if a page needs me to sign in?

Collection uses your own browser session and does not collect credentials. If a page is marked “Sign-in needed”, press “Open the site to sign in”, sign in in that tab, then press “Resume”. Pages that still need a sign-in are not saved, and the result says how many were left out.

The table appears only after scrolling or “Show more”. What should I do?

Open “If a page is missing text: content and JavaScript settings”, turn on “Scroll down to load content that appears later” or “Press ‘Show more’ to include the continuation”, and collect again. Tables drawn as images or inside a PDF are not exported as CSV.

Try Grab All Files on your browser.

Free saves up to 10 files per download in the file downloader, and one chosen page per run when you combine pages into HTML; that page’s linked files are saved 10 at a time with “Save the next 10”. Pro ($19.99 one-time, up to 3 devices) removes the per-download cap and combines multiple pages into one HTML.
