Convert JSE to JS

QUICK ANSWER
Is it possible to convert JSE to JS?
Yes - JSE converts to JS.

Decoding a .jse back to readable .js is the most common operation (for inspection). Use the Windows Script Decoder: a small open-source tool (see GitHub gist bcse/1834878) that reverses the Script Encoder substitution cipher. The result is plain JScript source that can be read in any text editor. This is trivial - the 'encoding' provides no real protection.

Also to JS: WASM · MJS · AXD
