A document is rarely just a document. A PDF is a contract, a payslip or a scan of a passport, and a spreadsheet export is a list of real customers with their real email addresses. Handing one of those to a free website to reformat it is a data transfer nobody wrote down.

None of that happens here. The file is read by your browser, converted in the tab, and written back out to your own disk. Open the Network panel while you use one and there is no request to watch.
