Is it really free, or is there a paid tier later?
Really free, permanently, and open source under the MIT licence. The reasoning is not generosity: everything it does happens in your browser, so it costs nothing to run and there is nothing to recover. A row limit would exist only to sell you the absence of a row limit.
Is there a row limit?
No. The editor draws the first few hundred rows for speed, and says so, but exports always contain every row.
Does my data get uploaded anywhere?
No, and it cannot be. The extension contains no network code — no fetch, no XMLHttpRequest, no WebSocket, no analytics. This is enforced by a check in the build that fails if any of those appear in the source, so it is verifiable rather than merely promised.
What permissions does it need?
It installs with access to no websites at all — there is no host permission in its manifest, so nothing runs anywhere until you invoke it. When you click the icon it reads that one tab. It also asks for storage (to pass a table to the editor tab, in memory), downloads (to save your file) and contextMenus (for the right-click item).
Why did my export come out with the columns shifted?
That is the merged-cell problem, and it is the main thing Table Grabber is built to get right. If you are seeing it here rather than in another tool, the table has a structure worth reporting — please send the URL.
The table on my page has thousands of rows but only twenty came through.
That grid keeps only the visible rows loaded. Open the editor and use 'Scroll for all rows', which scrolls the grid and collects the rest. If the data is paginated instead, use 'Walk every page'.
Why does Excel show my numbers as text?
Because the page wrote them as $1,234.00, which is a string. Tick 'Values as numbers' in the editor, or export as .xlsx, which writes genuine numeric cells so formulas work immediately.
Is it on the Chrome Web Store?
Yes. It passed review and the listing is live, so the normal way to install it is the Add to Chrome button at the top of this page — one click, and Chrome keeps it updated from then on.
Should I install from the Web Store or from the ZIP?
The Web Store, unless you have a reason not to: it is one click and it updates itself. The ZIP is the same build, kept here for anyone who would rather read every line before running it, or who cannot install from the store — you load it unpacked, and a published SHA-256 on this page lets you check the file arrived intact. Unpacked extensions do not update themselves.
Can I use it without installing anything?
Yes. The web version on this page runs the same extraction and export engine — copy a table from any page and paste it in, or paste the HTML. The extension exists for the things a web page cannot do: reading a table in place, scrolling a virtualised grid, and walking pagination.
Does it work on Firefox or Safari?
Not yet. It is built for Chromium browsers — Chrome, Edge, Brave, Opera, Arc and Vivaldi, version 116 or newer. A Firefox port is plausible since the code is nearly all standard web APIs.
Is it safe to run on a page I am logged into?
It reads what is on screen, which is the point, so an exported table can contain personal or account data — treat the file accordingly. Nothing is transmitted, and access ends when you leave the page.
