Convert CFA to DOC

When packet-capture details must be shared as an editable Word report, exporting them to a document is more useful than sending the capture to someone without an analyzer. The conversion creates a text report; it does not turn the captured network traffic into a Word-native representation.

What the CFA format contains

In this context, CFA is a ComProbe Analyzer capture file containing captured network traffic for protocol analysis. Wireshark can read supported ComProbe CFA files, but CFA is a capture format, not a word-processing document. Do not confuse it with unrelated uses of the same extension, such as Adobe audio cache files.

What the DOC format provides

DOC is Microsoft Word’s legacy binary document format. It supports editable text and broad compatibility with older Word versions; use DOCX instead when the recipient does not specifically require DOC.

Convert the capture to a Word document

1. Open the CFA file in Wireshark with File → Open. If Wireshark cannot recognize the file, obtain a supported export from ComProbe Analyzer; do not rename the extension to make it appear compatible.
2. Optionally enter a display filter to limit the packets shown. Choose File → Export Packet Dissections → As Plain Text, select the packet range and save the result as capture.txt.
3. Open capture.txt in Microsoft Word or LibreOffice Writer. Use File → Save As and select Word 97–2003 Document (.doc). If DOC is not required, save as DOCX to avoid the legacy format.

Quality and compatibility limits

This workflow exports a textual dissection, not the original capture, and does not preserve packet relationships as structured Word data. Binary payloads may appear as hex or be omitted, and the result can be long; filter or limit the packet range before exporting. CFA support depends on the file variant and Wireshark’s ability to parse it. Keep the original CFA for analysis, and inspect the report for addresses, credentials or payload data before sharing. Because captures can contain sensitive traffic and conversion requires protocol-aware parsing, an offline workflow is preferable to uploading the file to an online converter.
