Characters to pinyin for names?
Names are still tricky. There was even a heated discussion recently about the correct pronunciation of a very famous person called 甄嬛.

Some characters are neither wrong nor right, e.g.: 茜 some people pronounce it xi1 other pronounce it qian4 ... it just depends on their parents

Haven't tired any of these but there's a bunch of different software that will do this:

中英文姓名批量转换器

韦氏港台拼音姓名批量转换器

etc etc

but any software will still need people to proofread it &amp; maybe even confirm it with the people themselves...
