About CSV Master

We're on a mission to make CSV file processing simple, secure, and accessible to everyone—completely free.

Our Story

CSV Master was born from a simple frustration: why should working with CSV files require expensive software, complicated installations, or uploading sensitive data to unknown servers?

We built CSV Master to solve this problem. Every tool runs entirely in your browser using modern web technologies. Your data never leaves your device, there's no software to install, and everything is completely free.

What started as a simple CSV viewer has grown into a comprehensive suite of tools used by thousands of people every day—from data analysts and developers to small business owners and students.

Our Mission

To provide powerful, privacy-focused CSV tools that are accessible to everyone, regardless of technical expertise or budget. We believe that working with data should be simple, secure, and free.
