I need to embed the open-source x-spreadsheet component inside an existing PHP web application so users can work with data in a familiar grid interface. The key requirements are: users must be able to view and edit data directly in the browser. The data will be loadeed from an excel file already on the server and once the editing in x-spreadsheet is done the updated data should be saved back to the excel file on the server. If you have already wired x-spreadsheet or similar JS grids into PHP projects, that’s exactly the experience I’m looking for.
