What file formats do we support?

This is another of those questions we get asked a lot, so here's the answer for all to see. We currently support:

  • csv
  • doc
  • docx
  • jpg
  • kml
  • ods
  • odt
  • pdf
  • png
  • ppt
  • pptx
  • rdf
  • rtf
  • txt
  • xls
  • xlsx
  • xml
  • zip

It's likely we'll add  more as needed, which means this blog post will date. But you can check the very latest at any time by looking the code in GitHub.

    To date we've just published the older format (mainly because our own networks run older versions of MS Office). However, would be interested to know what the user base is actually running.
