Jexcel is a very light jquery plugin to embed a spreadsheet compatible with Excel in your website or application. You can create an excel-like table from a JS array, json or even a CSV file. You can use your copy and paste shortcuts to move data from excel straight to your jExcel spreadsheet and vice versa. You can easily integrate third-party jquery plugins to create your own custom columns, custom editors, and customize new features to your clients. jExcel has plenty of nice features such as key-value dropdown, CSV loading/exporting, multiple spreadsheets and much more. We have a large roadmap ahead for our jquery plugin and we are constantly improving, so don't forget to send us your ideas.It is a great free alternative for Handsontable.
