Your spreadsheets stay in your browser

Last updated: 10 September 2026

Spreadsheet processing

Rowwise reads, compares, searches, and exports your Excel and CSV files locally in your browser. Spreadsheet contents are not uploaded to or stored on Rowwise servers. Starting over, closing the tab, or refreshing the page clears the active comparison from the page.

Suggestions and email

The suggestion feature creates an email addressed to suggestions@row-wise.com and opens your email application. Your email provider handles that message under its own privacy terms. Please do not send confidential spreadsheets or sensitive personal data.

Advertising

Rowwise uses Google AdSense. Google and its advertising partners may use cookies, device identifiers, IP addresses, and information about visits to serve, personalize, and measure advertising, depending on your location and consent choices. Spreadsheet contents are not shared with Google by the comparison tool. Learn more about how Google uses information from sites that use its services.

Your choices

Where required, advertising consent choices will be presented through Google’s certified consent platform. You can also manage or block cookies using your browser settings. Blocking advertising cookies does not prevent local spreadsheet comparison.

External links

Rowwise may link to other websites. Those sites operate under their own privacy policies, and Rowwise is not responsible for their content or data practices.

Changes and contact

This policy may be updated when the service changes. The revision date above identifies the latest version. Questions or privacy requests can be sent to suggestions@row-wise.com.
