    ; For example, let's say we want construct simple JSON containing the base64 representation of the above JPG file.
    sb.i = CkStringBuilder::ckCreate()
    If sb.i = 0

        ProcedureReturn
    EndIf

    CkStringBuilder::ckAppend(sb,"{ " + Chr(34) + "jpg" + Chr(34) + ": " + Chr(34))
    ; GetEncodedSb appends the enocded representation of the binary data to the StringBuiler passed in the 2nd arg.
    CkBinData::ckGetEncodedSb(bd,"base64",sb)
    CkStringBuilder::ckAppend(sb,Chr(34) + " }")

    Debug CkStringBuilder::ckGetAsString(sb)

    ; Output looks like this:
    ;  { "jpg": "/9j/4AAQSkZJRgABAg...rcQ+vo//2Q==" }
