Achim -<br><br>If I were you, I'd go onto Microsoft's site and try and find info on the structure of the Excel Worksheet files. I don't know if they offer this for free or not, but if they do, you could use it to open the file and interpret its contents. <br><br>If open and interpreting it turns out to be too ineffective or hard with COBOL, I'd write a C/C++ DLL that would do it for me, and dump the contents of the file into an ascii text file that my cobol program can then read.
