To export tables to Excel with a macro, you can use a JavaScript library like SheetJS (formerly known as js-xlsx). SheetJS provides a set of APIs that allow you to read and write Excel files, including the ability to add macros to your Excel files.

Here’s an example of how you can use SheetJS to export a table to Excel with a macro:

// Import SheetJS library
import XLSX from 'xlsx';

// Define table data
const tableData = [
  ['Name', 'Age', 'Email'],
  ['John', 25, '[email protected]'],
  ['Jane', 30, '[email protected]'],
  ['Bob', 45, '[email protected]'],
];

// Create a new workbook
const workbook = XLSX.utils.book_new();

// Add a new worksheet to the workbook
const worksheet = XLSX.utils.aoa_to_sheet(tableData);
XLSX.utils.book_append_sheet(workbook, worksheet, 'Table Data');

// Add a macro to the workbook
const macroCode = `
  Sub MyMacro()
    MsgBox "Hello, World!"
  End Sub
`;
XLSX.utils.book_set_vba_strings(workbook, [macroCode]);

// Save the workbook as an Excel file
XLSX.writeFile(workbook, 'table_data_with_macro.xlsx');

In this example, we first import the SheetJS library and define some table data as a two-dimensional array. We then create a new workbook and add a new worksheet to it using the XLSX.utils.aoa_to_sheet function.

To add a macro to the workbook, we define the macro code as a string and use the XLSX.utils.book_set_vba_strings function to set it. Finally, we save the workbook as an Excel file using the XLSX.writeFile function.

When you open the resulting Excel file, you should see a new worksheet with the table data, as well as a macro named “MyMacro”. You can run the macro by pressing the “Macros” button in the “Developer” tab and selecting “MyMacro” from the list. When you run the macro, it will display a message box saying “Hello, World!“.
