Privacy and search measurement

Your CSV

Choosing Create XLSX passes the file bytes or entered text to a worker in your browser. The tool does not upload those bytes, send field values or a content preview to a server, fetch external file relationships, or save your input in cookies/browser storage. A fixed download name is used; the tool does not log user filenames or contents.

Reset, changing input and leaving the page terminate pending work and remove old download references. This is not secure erasure of your operating system, original files, browser memory or a workbook you have saved. Paste input can be normalized by the browser. You control the downloaded workbook and any application you open it with.

Website requests still exist

The browser requests this page and local stylesheet/JavaScript/worker files. Hosting and network providers can receive ordinary request metadata, including IP address, browser information and requested path. Browser-local conversion does not make internet page loading anonymous. Do not put CSV values or personal information into a URL. Source links visit the documentation provider only when followed.

Search-only measurement

No on-page analytics, action counter, Session Replay, account or content-logging service is included. Separately verified Google Search Console and Yandex Webmaster ownership can provide aggregate search impressions and clicks for the exact host after launch. These metrics do not prove tool use or human completion; sitemap submission does not prove indexing. Google and Yandex outcomes are kept separate.
