tech321,
The decode didnt work....you wouldnt expect a load of escaped nonsense in the decoded content if it had worked.
I was asking about thr spreadsheet cos i wondered if the encoded value included the .xlsx container or not.
You keep saying "i want it like i get it with curl cos its easy and straightforward" but what you need to appreciate is that readyapi!/soapui will do almost whatever you need for api testing as a consequence of its rich functionality, it enables the user to exercise so many different types of api, this means setup can be a lot more complicated in readyapi!/soapui.
[Disclaimer: no i don't work for Smartbear!]
On the decode webpage it says something like "for documents and binaries use the option further down the page" your stuff is of binary type (according to your Content-Type header).
As an aside. I think this is probably why your decode is failing!
Once youve run the decode successfully can you please take screenshot of the decoded binary?
I know this is tedious, but each time you give the forum more info, it answers a certain facet of your issue.
Nice one
Rich
