### Read and Process File Data with Excel API

Source: https://learn.microsoft.com/en-us/javascript/api/excel_view=visio-js-1

This example demonstrates how to read a file selected by an HTML input element, extract its base64 encoded content, and create a new Excel workbook using the extracted data. It utilizes the `FileReader` API and the `Excel.createWorkbook` method.

```TypeScript
const myFile = <HTMLInputElement>document.getElementById("file");
const reader = new FileReader();

reader.onload = (event) => {
    Excel.run((context) => {
    // Remove the metadata before the base64-encoded string.
    const startIndex = reader.result.toString().indexOf("base64,");
    const mybase64 = reader.result.toString().substr(startIndex + 7);

    Excel.createWorkbook(mybase64);
    return context.sync();
    });
};

// Read in the file as a data URL so we can parse the base64-encoded string.
reader.readAsDataURL(myFile.files[0]);
