Our Mission

CSV Viewer was created with a simple goal: make working with CSV data as easy and accessible as possible. Whether you are a data analyst, a developer, a student, or anyone who needs to quickly view and manipulate tabular data, our tools are designed to help you get the job done — fast, free, and without compromising your privacy.

What We Offer

CSV Viewer provides a suite of free online tools built for everyday data tasks:

• CSV Viewer — Upload or paste your CSV data to instantly view it as a clean, sortable, and searchable table. Edit cells directly in your browser.
• Chart Generator — Transform your CSV data into beautiful bar charts, line charts, pie charts, area charts, and scatter plots. Export them as PNG images.
• CSV Creator — Build CSV files from scratch using an interactive table editor. Add columns, fill in your data, and download the result instantly.
• Excel/CSV Converter — Convert Excel files (.xlsx, .xls, .xlsm) to CSV and CSV to Excel, directly in your browser. No file upload to any server.

Privacy First

Your data stays on your device. All processing is done locally in your browser — we never upload, store, or access your CSV files. This is not just a feature, it is a core principle of how we build our tools. You can use CSV Viewer with complete confidence, even with sensitive or confidential data.

Built for Performance

CSV Viewer is optimized to handle large datasets efficiently. We use virtual scrolling technology and Web Workers to ensure smooth performance even with files containing thousands of rows. The interface is responsive and works seamlessly on desktop, tablet, and mobile devices.

Who We Are

CSV Viewer is developed and maintained by Magne Jean, a web developer based in Tours, France. The project started as a personal tool to solve the frustration of opening CSV files and has grown into a comprehensive suite of data tools used by thousands of people worldwide.

Technology

CSV Viewer is built with modern web technologies including Next.js, React, and Tailwind CSS. It is hosted on Vercel for fast, reliable global delivery. We use PapaParse for robust CSV parsing and Recharts for data visualization.
