Parse existing excel from template into python datastructure

[DanCardin]

Given a htmxl-generated excel file, and the associated template used to generate it, provide a mechanism to reverse engineer a format that's better than hand-writing a parser for the excel format.

hunter said something like

def capture_sheet_details(fn):
    @functools.wraps(fn)
    def wrapper(element, writer, styler, style):
        element, recording = fn(element, writer, styler, style)
        if element.id:
            writer.sheet.details[element.id] = {
                'bounding_ref': get_bounding_ref(recording),
            }

    return wrapper

that may or may not be useful
