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.

Privacy-friendly audience measurement

Cloudflare Web Analytics provides aggregate traffic and performance information such as page views, visits, referrers, country, browser type, and page-load performance. It does not use cookies or local storage, does not fingerprint visitors, and is not used for advertising or user-level profiles.

Local browser data

This site does not use cookies or local storage for analytics. Downloads are created locally, and current tool data is cleared when the tab is closed or refreshed.

Cloudflare

Cloudflare may process standard request information for security, reliability, and aggregate Web Analytics. Selected files and their contents are never part of those requests.

Limits

Files are limited to 50 MB each. Closing or refreshing the page clears current working data from memory.
