We are using CANoe tool to capture the CAN and Ethernet real time data, and stored in .blf file format. I would like to reuse captured data in Matlab. So, required a solution from Wireshark to read the Ethernet data from .blf file without using the CANoe tool and save it in readable format such as .csv. I appreciate your support.

Can you provide a sample capture file and more information about what data should be in the .csv?

It should be possible to read .blf files with the developer version of Wireshark.

Wireshark 4.4.x and 4.2.x both include some support for reading BLF files.

There are various ways of producing CSV files with Wireshark or TShark. There's an "Export packet dissections as CSV" option in Wireshark, which produces a CSV file from the columns in the summary pane. With TShark, you can also specify specific per-packet fields with the -T fields option, along with -e options specifying fields by name.
