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.
Your browser reads the file, converts it in the tab and saves the result to your disk. The Network panel shows no request uploading the file. Typed or pasted text saves privately when signed in. Opened CSV or JSON text stays in this browser’s local storage. Analytics settings in the footer turns Google Analytics off.
