It decodes transactions as well, just paste raw transaction to the Raw Transaction field.
Ah, ok so when I input my own raw transaction data the JSON textarea is updated. Then I copy the out scriptPubKey hex and use the brainwallet converter to verify that the proper address has been encoded.
So I get some coins going back to my source address and some coins goes to destination address. Then there are some coins "missing" from the out array, is this the fee?
