By default, all software supports multiple file extensions. MacVim supports at least 21 different file extensions. The basic files that MacVim supports are .JSON. However, not all of the extensions listed on the list are always used to save the effects of work in MacVim. Very often, files with such extensions are used as source data files used by MacVim.
MacVim can be used to convert file formats between the file extensions listed below. You can open a file with one of the file extensions below via MacVim and try to save it in another file format, also supported by MacVim.
