Welcome to xlsx-to-csv.com ("we," "our," or "us"). We are committed to protecting your privacy and ensuring the security of your data. This Privacy Policy explains how we handle information when you use our XLSX to CSV converter tool (the "Service"). By using our Service, you agree to the practices described in this Privacy Policy.
Client-Side Processing: All file conversions happen entirely in your web browser using JavaScript. When you upload an XLSX or XLS file to convert to CSV format, the file never leaves your device or gets transmitted to our servers.
No File Storage: We do not store, save, or have access to any files you upload or convert using our Service. Your data remains on your device at all times during the conversion process.
Temporary Memory Only: Files are temporarily held in your browser's memory only during the conversion process. Once you close the browser tab or navigate away from the page, all data is immediately cleared from memory.
We may collect non-personal information about how you interact with our Service, including:
Our web server automatically collects standard technical information such as IP addresses and access times for security and analytical purposes. This information is aggregated and does not identify individual users.

Analytics Cookies: We may use analytics services to understand how visitors use our Service. These tools help us improve the user experience by analyzing usage patterns, popular features, and technical performance. Analytics data is collected in an anonymized format.
