Order list export format problem

Do people use the TSV/CSV order export function? I have been having problems with it - both open office and notepad++ choke on the files I get. It turns out each entry is padded with a large number of NULLs at the end. (A NULL is a character coded with a zero value). Anyway, removing the NULLs makes the data usable. On Linux there is a simple script to do this but I haven’t yet found a windows way. Anybody got a solution (other than Tindie fixing their broken tools)?
