Got an article about using xtopdf, my open source PDF creation/conversion toolkit, published by Packt Publishing of the UK.
Its here. This article shows how to use the features in xtopdf v1.3 and v1.0 to convert multiple different input formats to PDF: text, DBF, CSV, TDV and XLS. Also, I've started a products page on my site - only xtopdf there now, but will be updating it with more products over time. Vasudev.
