  This Paper summarises the operation of software developed for the analysis of
workbook structure. This comprises: the identification of layout in terms of
filled areas formed into "Stripes", the identification of all the Formula
Blocks/Cells and the identification of Data Blocks/Cells referenced by those
formulas. This development forms part of our FormulaDataSleuth toolset. It is
essential for the initial "Watching" of an existing workbook and enables the
workbook to be subsequently managed and protected from damage.
