TableGrab is a Chrome extension that finds every table on the page you are viewing, including HTML tables, ARIA grids and div-based grids. Pick one and copy it straight into Excel or Google Sheets as clean tab-separated data, or download a CSV. Merged cells are filled in so columns line up, and CSV output is protected against spreadsheet formula tricks. It only reads a page when you click it, needs no account and uploads nothing. Free for tables up to 100 rows, with a one-time US$15 Pro for unlimited rows, .xlsx export and more.
Copy-pasting a table from a web page into a spreadsheet usually breaks it: merged cells shift every column after them and some "tables" are really divs. I'm a solo maker in Brisbane, Australia, and built TableGrab so tables paste cleanly, privately and with a pay-once price.
