I'm looking for an (online) tool to convert a long list of DOI's (1000+) into citation information. There are several tools that let you enter one DOI at a time, such as doi2bib or Crossref but those would take too much time. I found one batch converting tool from the NCBI, but unfortunately it only works for medical publications (which these aren't). I would be fine with any type of citation style (I can process it to my needs).
Any help would be appreciated!
