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 supported format
writers automatically insert the data blobs if it is present in the workbook and
associate with the worksheet names.
Custom Code Names (click to show)
The workbook code name is stored in wb.Workbook.WBProps.CodeName. By default,
Excel will write ThisWorkbook or a translated phrase like DieseArbeitsmappe.
Worksheet and Chartsheet code names are in the worksheet properties object at
wb.Workbook.Sheets[i].CodeName. Macrosheets and Dialogsheets are ignored.
The readers and writers preserve the code names, but they have to be manually set when adding a VBA blob to a different workbook.
Macrosheets (click to show)
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".
Detecting macros in workbooks (click to show)
The vbaraw field will only be set if macros are present, so testing is simple:
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');
}
