Shellcode and Byte String Formatter
Paste bytes in one form and get every other form back: spaced hex, \x escaped, a C array, a python byte string, base64, decimal and ASCII. The reformatting you do constantly when moving shellcode or a payload between tools.

Why so many formats
Every tool wants bytes its own way. A debugger takes raw hex, C source wants an array, a python exploit wants b"\x..", and a web field might need base64. This just does the translation so you stop hand-editing.
FAQ
Can it read \x escaped input too?
Yes. Set the input mode to hex and it strips 0x, \x, spaces and separators before parsing.
