-'On the fly'-creation of an excel file. The file is build in the moment when the user clicks on the download button.
+Hint: For up/downloading of excel files (no modification), check the generic Form
+`input-upload`_ element and the report 'download' (`column_pdf`_) function.

+This chapter explains how to create Excel files on the fly.
+
+The Excel file is build in the moment when the user request it by clicking on a
+download link.
+
+Mode building:
 
 * `New`: The export file will be completely build from scratch.
 * `Template`: The export file is based on an earlier uploaded xlsx file (template). The template itself is unchanged.
 
-Injecting the data is done in the same way in both modes.
+Injecting data into the Excel file is done in the same way in both modes: a Typo3 page (rendered without any HTML header
+or tags) contains one or more Typo3 QFQ records. Those QFQ records will create plain ASCII output.
 
 If the export file has to be customized (colors, pictures, headlines, ...), the `Template` mode is the preferred option.
 IT's much easier to do all cusomizations via Excel and creating a template than by coding in QFQ / Excel export notation.
