Need log report by script

Hi,

I need to match Template file 'paragraph style’ names with ‘Standardized InDesign style names.xls’ (we defined already our standard style names in excel sheet), if any style name variation between Template and excel sheet, generate the log report for the mismatched ‘paragraph style name’.

For instance My Template file paragraph style names: TT, CT, H1, H2, H3    

                   My excel sheet paragraph style names: TTL, CT, H1, H2, H4

Here mismatched style names is excel sheet: TTL, H4 this detail has to generate in log report.

Pls help by script.

Thanks
