It seems that users wanting to convert Scratch projects 2.0 (.sb2) to Scratch projects 1.4 (.sb) prefer to use the Retro Converter conversion utility as the original Scratch program does not posses the capability to produce older version of projects in the latest versions of the program. It is not perfect but should be more than enough for some basic conversion.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
