UDP (User Datagram Protocol) is a connectionless protocol that allows data to be sent between devices on a network. When analyzing network traffic using a tool like Wireshark, it can be helpful to view the UDP payload as text. This can provide valuable insights into the information being transmitted.
In this article, we will walk you through the steps to show UDP payload as text in Wireshark. Whether you are a beginner or an entry-level user, we have simplified the process for you.
Step 1: Capture UDP Traffic
The first step is to capture the UDP traffic using Wireshark. Launch Wireshark and select the network interface you want to capture packets from. Click on the "Capture" button to start capturing packets.

Once the packets are being captured, you will see them displayed in the Wireshark main window.
Step 2: Filter UDP Packets
Next, we need to filter the captured packets to display only UDP packets. This will help us focus on the UDP traffic and make it easier to locate the specific packets we are interested in.
To filter UDP packets, type "udp" in the filter box at the top of the Wireshark window and press Enter. Wireshark will now display only the UDP packets.

Step 3: Locate the UDP Packet of Interest
Now that we have filtered the packets, we need to locate the specific UDP packet whose payload we want to view as text. Look through the list of packets and find the one that corresponds to the communication you are interested in.
Click on the packet to select it, and you will see the details of the packet displayed in the lower part of the Wireshark window.
Step 4: View UDP Payload as Text
To view the UDP payload as text, we need to locate the "User Datagram Protocol" section in the packet details. Expand the section by clicking on the arrow next to it.
Inside the "User Datagram Protocol" section, you will find the "Data" field. This field contains the payload of the UDP packet. Right-click on the "Data" field and select "Copy" from the context menu.

Now, open a text editor or any other application where you can paste the copied text. Paste the copied text into the application, and you will see the UDP payload displayed as text.
Step 5: Analyze the UDP Payload
Now that we have the UDP payload as text, we can analyze the information it contains. The payload could be in various formats depending on the application or protocol being used.
For example, if the UDP payload contains HTTP traffic, you might see HTTP headers and HTML content. If it contains DNS traffic, you might see domain names and IP addresses.
By analyzing the UDP payload, you can gain insights into the data being transmitted and identify any potential issues or anomalies.
Conclusion
In this article, we have explained how to show UDP payload as text in Wireshark. By following these steps, you can easily view and analyze the UDP payload for a deeper understanding of the network traffic.
