I am currently working on standardising the infoboxes used in articles about spacecraft. I have already replaced around 500, mostly using AWB, however AWB does not have the flexibility to support many of the necessary edits, as a separate regex is needed for each order and combination of fields and formats, making widespread use difficult.
I am now using a custom semi-automated tool. It is not a bot - like with AWB I am still reviewing each edit before posting it, however as with any large-scale task there are bound to be a few small errors somewhere. If you notice any, or have any questions, please use my talk page to contact me, I will be monitoring it closely while I am actively editing.
