Open Data Editor

What Open Data Editor is

Open Data Editor is a free, open-source desktop app that checks tabular data for errors and points out what needs attention, without requiring users to code. It is intended for nonprofits, data journalists, activists, and public servants working with tabular data. The project names Excel, Google Sheets, and CSV as relevant formats. Its maker describes the app as local-first, preserving privacy while users work with their data. The project aims to help users apply FAIR principles and uses open standards such as Frictionless Data specifications. AI-assisted data-quality features can identify anomalies, suggest corrections, and handle large, dense datasets. Download links are provided for Debian/Ubuntu, macOS, and Windows. Open Knowledge Foundation also offers a free online, gamified data-literacy course for non-technical users working with tabular data, and invites questions by email. The foundation was founded in 2004 and is headquartered in London, England. Its maker says the Digital Public Goods Alliance recognised Open Data Editor as a digital public good in 2025.
