Handsontable
Handsontable is a JavaScript data grid component designed to bring a spreadsheet-like experience into web applications, allowing users to interact with data in a familiar, Excel-style interface.

It supports advanced editing capabilities, including inline editing, copy and paste with Excel-compatible clipboard, undo and redo actions, and keyboard navigation that mirrors common spreadsheet tools. It provides extensive functionality for managing data, such as sorting, filtering, grouping, moving, hiding, and freezing rows and columns, along with customizable cell types, validation rules, and conditional formatting.

Edit CSV
Edit CSV is a free online tool that allows users to edit CSV files through a table-based user interface. It offers features such as undo/redo functionality, column sorting by clicking on header text, and the ability to rearrange rows and columns by dragging. Users can resize rows and columns, and navigate efficiently using keyboard shortcuts to move to the first cell in a row, to move to the last cell, to jump to the first cell in a column, and to reach the last cell. You can also add a line break within a cell. To delete a row or column, hover over it and click the trash icon. Double-clicking a column's resize handle adjusts its width to fit the content; double-clicking an auto-sized column sets its width to 200px, which is useful for very wide columns. It also provides a context menu accessible via right-click and supports copy-pasting using the tab key as a separator, similar to Excel.
