HTML Table to CSV Converter

Yes. Every <table> in the pasted HTML is converted, and the resulting CSV blocks are output one after another, separated by a blank line.

Header cells (th) and data cells (td) are both included as ordinary fields, in document order, so your header row comes out as the first CSV row.

Cells are read once each, in source order, without expanding spans. Simple tables convert exactly; tables with merged cells may need manual touch-up.

No. Parsing and conversion happen entirely in your browser; nothing is uploaded.

Almost always a merged cell. A cell spanning two columns is read once, so that row is one field short of its neighbours — the data is not lost, it is just not duplicated across the span. Re-add the repeated value by hand if the destination needs a rectangular grid.

No. It goes through the browser's own HTML parser, which repairs unclosed tags and stray attributes exactly as a browser would, so markup copied straight out of a page works. Cell text is also whitespace-normalised, so line breaks and source indentation collapse to single spaces.
