jExcel: A library to read, write, display, and modify Excel files. It is a very light, totally free, jquery plugin to embed a spreadsheet compatible with Excel in your website or application. You can create a 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 colums, custom editors, and customize new features to your clients; Chart.js: Simple, clean and engaging charts for designers and developers. Visualize your data in 6 different ways. Each of them animated, with a load of customisation options and interactivity extensions.
jExcel can be classified as a tool in the "Javascript Utilities & Libraries" category, while Chart.js is grouped under "Charting Libraries".
