About CSV Editor Online
CSV Editor Online is a free, browser-based tool for opening, editing, cleaning, and exporting CSV files. Users can drag and drop a file or paste CSV text, then choose the delimiter and character encoding on import. The data appears in a browser table where it can be searched, edited cell by cell, have columns renamed, and have rows removed. The cleaned file can then be downloaded as CSV. The site states that no signup is required.
The tool runs client-side, meaning the file is processed in the browser. The site says the data stays local during normal editing workflows. Performance depends on the user's device memory, browser, and file complexity. The site notes that very large files may be easier to clean in smaller chunks.
