The read data from Excel file is displayed in HTML Table using JavaScript. TAGs: JavaScript, Excel, HTML, Table The following code example contains two methods that correspond to the two approaches, DOM and SAX. The latter technique will avoid memory exceptions when using very large files. To try them, you can call them in your code one after the other or you can call each method separately by commenting the call to the one you would like to exclude.
