Limits: 2 MiB input / 50 tables / 10,000 rows / 100 columns / 500,000 cells. No external fetch, storage, or analytics is used.

HTML is parsed as a string; scripts, styles, iframes, and other resources in the input are never executed.
You select a table and explicitly save after reviewing the result. Editing input invalidates the old result.
Merged cells, quotes, commas, line breaks, Unicode, and empty cells remain text in the CSV.
