I am developing Excel Add-in for exporting worksheets and ranges to DBF files.

If anybody wants to take it for a spin, please respond or send me a private message.

This is fully functional version with no major bugs, unless you'll find some. Find screenshots attached to this message.

Supports Excel 2007 to 2013. The addin is launched from worksheet cell's context menu.
DBF versions: dBase, VFP
Does not require ODBC, OLE DB, ADO.NET etc.
Data types supported: Character, Logical, Date, DateTime, Numeric, Integer, Double, no Memo support yet.
Exports either whole worksheet or a rectangular contiguous range.
Automatically skips hidden columns and rows filtered out.
Determines the most suitable data type for each exported column. Data types can be manually overridden.
Allows to modify output table structure: names, data types, width, decimals; selected columns can be skipped
Allows to set code page mark.

The setup may request installing run-times for .NET 4.0 and VS2010 Tools for Office.
