Greets... and batch uploading.

Theoretically you can export your dbase tables or even certain table cells to an xml file.
But you'd still need to adjust xml structure to GS "compliant" - I assume you do not have to provide all xml tags, as they might just be ignored - and slice the dbase xml file into portions (GS pages).

Anyway manual input is a must have.
You may search for some helpful apps, but I'm not familiar with XML converting tools.
Start with this one: xml-converter.com

you are an adventurous soul, yojoe! HA!
i suppose it would become, in the end, a 'six of one, half dozen of the other' situation in terms of manual editing.
oh well... i did it once. i guess i can do it again.
although, if i might suggest, having a 'blog import' facility native to GS (or its blog plugins) might not be a bad marketing approach. if people knew that, within certain constrains, they could move their blog, it would encourage people to adopt the platform.
(that's just me spouting off...)
cheers!
