Understanding CAP and CSV file formats
CAP files are packet capture files generated by network analysis tools such as Wireshark or tcpdump. They store raw network traffic data, including headers and payloads, for in-depth analysis of network activity. CSV (Comma-Separated Values) files are plain text files used to store tabular data, where each line represents a row and columns are separated by commas. CSV files are widely supported by spreadsheet applications and data analysis tools.
Why convert CAP to CSV?
Converting a CAP file to CSV format allows you to analyze network packet data in spreadsheet software, perform data filtering, or import the data into databases and data analysis tools. This conversion is especially useful for generating reports or conducting statistical analysis on captured network traffic.
