This doesn't need to be renamed

Yes, naming is not an issue. It was just my idea. Keeping the name same is also fine

final SummaryInformation summaryInformation = workbook
.getSummaryInformation();
if (summaryInformation != null) {

Can you call this processWorksheet?

would it be better to just pass a HSSFWorksheet in the input instead of a workbook and sheetNumber?

SummaryInformation summaryInformation = workbook.getSummaryInformation();

if (summaryInformation != null) {
this.processDocumentInformation(summaryInformation);
}

if (workbook.getNumberOfSheets() < sheetNumber) {
throw new IllegalArgumentException("invalid sheet number: " + sheetNumber);
}

HSSFSheet sheet = workbook.getSheetAt(sheetNumber);

this.processSheet(sheet);

htmlDocumentFacade.updateStylesheet();
}

public void setCssClassPrefixCell(String cssClassPrefixCell) {
this.cssClassPrefixCell = cssClassPrefixCell;
}
