Hi Jos,

Excel-free standalone Excel-and-Libreoffice output and imports, I recommend this: https://xlsgen.arstdesign.com/

Do not be fooled by the dull web site and or the relatively messy documentation, the product is robust indeed and definitely works with and from VFP:-) The only caveat: it is certainly fast and sometimes much faster than MS-office automation. But it will not compete on speed when it comes to mangling VERY large excel output or imports. Other than that definitely a hidden gem...

The stuff is not free and open-source. But there is as robust C++ code base behind it. And, well, the developper has to make a living!
