I am looking for a way in Solaris to open an existing Excel spreadsheet so I can add data to sheet 1. This is a spreadsheet that I FTP'd from Windows. Sheets 2-4 already have macros and graphing and stuff. I simply need to refresh the data on sheet one via an database query. The only way I have been able to open up an Excel file for wiring is if a create a whole new file. How can I open up an existing Excel file for writing?
