React Data Grid: Excel Import
Below we illustrate how you might import an Excel spreadsheet into AG Grid using a third-party library - in this example we're using xlsx-style.
In this example we're providing a simple Excel file for importing but in your application you could allow uploading of Excel files by end users.
The spreadsheet contains a few rows of simple data, which the example parses and sets as row data.
The spreadsheet can be downloaded here.
