By default, all software supports multiple file extensions. OpenCOBOL supports at least 2 different file extensions. The basic files that OpenCOBOL supports are .CBL. However, not all of the extensions listed on the list are always used to save the effects of work in OpenCOBOL. Very often, files with such extensions are used as source data files used by OpenCOBOL.
OpenCOBOL 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 OpenCOBOL and try to save it in another file format, also supported by OpenCOBOL.
