Trigger the "EXPORT" to "Microsoft Excel Workbook" option from Adobe Acrobat Standard DC using VBA

I don't believe you can. You create a routine to extract the field data in the same format though. For example, build a string that has the list of field names delimted by tabs and add the list of corresponding field value, and set the value of a hidden multiline form field to those two lists, separated by a new line. This will give you the form data in tab-delimited format that can readily be imported into a spreadsheet. This has the additional advantage of only exporting specific fields and allows you to customize the field order.
