Javascript Excel - Excel Formulas
This sample shows how to create an Excel worksheet with custom formulas using the Infragistics Ignite UI for jQuery JavaScript Excel library.
This sample uses CTP (Community Technical Preview) features. The API and behavior may change when these features are released with full support.
This sample is designed for a larger screen size.
On mobile, try rotating your screen, view full size, or email to another device.
This example uses the AVERAGE function to display the average values for a column of numbers. You can use the Excel library in browsers and in other JavaScript runtimes such as Node.js.
