Your files stay yours.

Last updated 9 August 2026

File processing

Tools For CSV processes selected files entirely in your browser. File contents and filenames are not uploaded to us, stored by us, or included in server logs.

Optional analytics

Google Analytics is disabled unless you choose “Accept analytics.” If accepted, it may collect page views, general interactions, approximate location, and browser or device information. We do not enable advertising features, and analytics never includes file contents, filenames, cell values, rows, or generated downloads. The analytics measurement ID is G-P29RHFQCMG.

You can decline analytics or change your choice at any time using “Cookie settings” in the footer. Declining does not affect any tool.

Local browser data

The site does not require an account. Your analytics choice is saved in your browser’s local storage so the site can remember it. If analytics is accepted, Google Analytics may set cookies such as _ga. Downloads are created locally and are handled by your browser and device.

Cloudflare

The public pages are delivered by Cloudflare. Like most hosting providers, Cloudflare may process standard request information such as an IP address, browser details, requested page, and time for security and reliability. Your selected files are never part of those requests.

Limits

Files are limited to 50 MB in this release to protect browser performance. Closing or refreshing the page clears the current working data from memory.
