I have a lot of GATT packets like the one below. I only need the value part for further processing somewhere else. How can extract that part to .csv or file types that are easy to process?

Frame 466: 20 bytes on wire (160 bits), 20 bytes captured (160 bits)
Bluetooth
Bluetooth HCI H4
Bluetooth HCI ACL Packet
Bluetooth L2CAP Protocol
Bluetooth Attribute Protocol
    Opcode: Write Request (0x12)
    Handle: 0x001c (Unknown: Unknown)
        [Service UUID: CustomUUID]
        [UUID: CustomUUID]
    Value: 112233445566
