I'm evaluating this product as a tool to convert spreadsheets generated in SpeadsheetML (Office 2003 XML) format to xlsx and xls.
The converted files :
1) Lose their filters. The original sheet has a filter on every column heading.
2) Changes a custom date format in the report heading from "dd/mm/yyyy hh:mm" to "yyyy'-'mm'-dd dd':'mm':'ss'Z'".
If there is a way of fixing these issues easily I'll purchase the product.
In the meantime I'll look at some of the other offerings.
