The Smart Octopus can process all major file formats, including Microsoft Office (Word, Excel, Powerpoint), text files (TXT), rich text files (RTF), PDFs, and source files (web content). However, document format depends on the type of service you choose (editing, translation, web).
For the editing/revision of a manuscript, I prefer receiving the document in Word format (.doc, .docx), although I can also work with TXT and RTF files. Please also send me the figures and/or tables (if any), including figure and/or table legends, as it can be very difficult to interpret the text without them.
For the translation of a document, I accept all the major file formats listed above, while for web services you can either send me the document that needs revision/translation with all encoding or mark-up languages removed (in .txt, .doc, .rtf, etc.) or you can ask me to revise/translate the source files directly (.asp, .htm(l), .php, .xml, java to cite some).
