There is an INI setting that will send the ExcelDirect output directly to a CSV file. Details are in the ReadMe Help file with most applications. This is from the BankRec release note:
Excel Direct (from finders, smart finders and from grids in some modules) can be configured to export an ASCII CSV file (instead of sending data direct to Excel) and start an application that automatically opens the file. This allows export when Excel is not installed and provides support for other spreadsheets such as OpenOffice.org. Note that unlike Excel Direct there is no formatting with CSV. To enable this functionality, entries must be made manually in the file \softrak\system\ssi2xl.ini. Refer to the Configuring Excel Direct to Export to CSV topic in the Readme help for details.
