Local CSV Viewer

Open a CSV file you choose to view its table and search rows across any column. The extension detects commas, semicolons, or tabs automatically, and you can change the delimiter manually. A built-in sample lets you try the table without choosing a file. It supports CSV files up to 2 MB with at least two columns and explains empty or malformed files. The file is read and filtered in the popup's memory. It is not changed or uploaded. You can open another file or reset the view.
