About Project CSV

Project CSV is a browser-based tool for opening and editing .csv (comma-separated values) files. You select one or more CSV files, adjust basic or advanced CSV settings if needed, and generate editable tables; cells, including column names, can be changed by clicking on the text, and the edited table can be downloaded back to your computer. The interface is described as fitting both mobile and desktop browsers.

According to the site, all file data is processed locally on the user's end and is not sent over the network, and it states that no other data is collected, stored or sent. The page can also be downloaded for offline use, which the project presents as an alternative to a desktop application. The project describes itself as free, open source and released under the GNU General Public License v3, with the source and related content hosted on GitHub. Refreshing the page resets any changes to all tables.
