SpreadJS is a high-performance JavaScript spreadsheet and data presentation component designed for enterprise web applications. It enables developers to deliver Excel-like functionality directly within their web solutions, providing advanced features such as data binding, complex calculations, pivot tables, charts, and extensive formatting options. Fully compatible with modern JavaScript frameworks like React, Angular, and Vue, SpreadJS allows seamless integration and customization, empowering development teams to create interactive, data-driven user experiences without relying on external spreadsheet applications.
The SpreadJS 18.2 adds a new Transform command which enables you to apply LAMBDA functions directly to a selected range of cells and replace the original content with calculated results. This simplifies data transformations - whether mapping, filtering, or reshaping - into a clean, single-step process. With this feature, you can select any range and apply a custom LAMBDA formula - for example, converting units, adjusting values, or formatting entries - and have SpreadJS overwrite the selection with the computed results immediately. This removes manual steps like inserting formulas in separate cells, copying values, or pasting back as values. This feature integrates with SpreadJS’s existing LAMBDA capabilities to offer more interactive and efficient spreadsheet manipulation.
