Is there a way to tweak Excel 2007, with an add-in perhaps, to enable it to save spreadsheets in the dbase IV file format?
Solution 1:
Seems to be various converters to/from dBase here: dbfView
I see options for Excel 2003, 2007, and CSV there.
Solution 2:
I doubt this. But you can export to, let's say, csv file, and then use converter to get your dBase file. I believe getting CSV (or other open format) to dBase converter is much easier than trying to convert directly to dBase from Excel.
