Number Now only supports exporting to CSV (Comma Separated Variable) files. We chose to support CSV because it is open and be can used by any program. At this time there are no plans to add support for exporting to other file types to Number Now.
Number Now does not open any type of files. It is only used to generate numbering files in CSV (Comma Separated Variable) format for use in other programs.
Number Now will export a CSV file that may be used in Microsoft Word, Adobe InDesign and other programs.
