Swap text between commas and among the colons

i have a file that contain repetitive code like this an i just want to

swap a roll/column? (how to say?) of y and z , every number is different in here nothing in here is same number

Example:

xxxx,xxxx,yyyy,xxxx,xxxx,zzzz:xxxx:xxxx:xxxx:xxxx:
xxxx,xxxx,yyyy,xxxx,xxxx,zzzz:xxxx:xxxx:xxxx:xxxx:
xxxx,xxxx,yyyy,xxxx,xxxx,zzzz:xxxx:xxxx:xxxx:xxxx:
xxxx,xxxx,yyyy,xxxx,xxxx,zzzz:xxxx:xxxx:xxxx:xxxx:

Into:

xxxx,xxxx,zzzz,xxxx,xxxx,yyyy:xxxx:xxxx:xxxx:xxxx:
xxxx,xxxx,zzzz,xxxx,xxxx,yyyy:xxxx:xxxx:xxxx:xxxx:
xxxx,xxxx,zzzz,xxxx,xxxx,yyyy:xxxx:xxxx:xxxx:xxxx:
xxxx,xxxx,zzzz,xxxx,xxxx,yyyy:xxxx:xxxx:xxxx:xxxx:

x , y , z = different numbers

his should do the job (in Notepad++):

• Ctrl+H
• Find what: ^((?:[^,]+,){2})(\d+),((?:[^,]+,){2})(\d+)
• Replace with: $1$4,$3$2
• Replace all

Explanation:

^           : start of line
(           : start group 1
  (?:       : start non capture group
    [^,]+   : 1 or more non comma
    ,       : a comma
  ){2}      : end group, must appear twice
)           : end group 1 
(\d+)       : group 2, 1 or more digits 
,           : a comma
(           : start group 3
  (?:       : start non capture group
    [^,]+   : 1 or more non comma
    ,       : a comma
  ){2}      : end group, must appear twice
)           : end group 3
(\d+)       : group 4, 1 or more digits

Replacement:

$1$4,$3$2   : group 1 group 4  comma group 3 group 4
