#### VBA and Macros
|
|
|
|
VBA Macros are stored in a special data blob that is exposed in the `vbaraw`
|
|
property of the workbook object when the `bookVBA` option is `true`. They are
|
|
supported in `XLSM`, `XLSB`, and `BIFF8 XLS` formats. The `XLSM` and `XLSB`
|
|
writers automatically insert the data blobs if it is present in the workbook.

|
Older versions of Excel also supported a non-VBA "macrosheet" sheet type that
|
|
stored automation commands. These are exposed in objects with the `!type`
|
|
property set to `"macro"`.

|
|
|
|
The `vbaraw` field will only be set if macros are present, so testing is simple:
|
|
|
|
```js
|
|
function wb_has_macro(wb/*:workbook*/)/*:boolean*/ {
|
|
if(!!wb.vbaraw) return true;
|
|
const sheets = wb.SheetNames.map((n) => wb.Sheets[n]);
|
|
return sheets.some((ws) => !!ws && ws['!type']=='macro');
|
|
}
|
|
```
