How to modify data before export with Buttons API?

Description of problem:
I am using the Buttons plugin to export a printable version and an Excel file. For the export I would like to modify the cell content, either the HTML created with

{
  columns: [
    {
       data: function ...
    }
  ]
}

or the original data object. In case of modifying the HTML, I'm thinking about adding a CSS class to the elements that should be removed from the export.

The only way that seems to come close is exportOptions from the Buttons API, but I cannot figure out how to modify the data before export. Could you please give a hint?

I discovered now the customize: (window, button, dt) => {...} option but I cannot select the elements that I want to remove from the DOM of the print window with window.document.body.querySelectorAll('.noexport'); because the HTML has already been cleaned.

I managed to do it with exportOptions, see: https://live.datatables.net/sumolevi/2/edit

The comments brought me on the right track.
