Canmatrix is a Python library that reads, writes, converts, compares, and modifies CAN (Controller Area Network) database formats such as .dbc, .arxml, .dbf, .kcd, .sym, and more. It also ships CLI tools (canconvert, cancompare) and supports CAN message encoding/decoding.

Use cases

• convert a dbc file to arxml
• read and parse can database files in python
• compare two can matrix files for differences
• encode and decode can messages from a dbc
• convert kcd to dbc
• generate wireshark lua dissector from can database
• merge or modify can signal definitions programmatically

When to choose

• you need to convert between automotive CAN database formats like dbc, arxml, kcd, dbf, or sym
• you want to programmatically inspect or edit CAN matrices in Python
• you need CAN message encoding/decoding based on a database file
• you want to generate wireshark dissectors or scapy definitions from a CAN database

When to avoid

• you need real-time CAN bus communication or hardware interfacing (use python-can instead)
• you work with J1939, SOME/IP, or other higher-layer protocols not covered by CAN matrices
• you need a GUI tool for editing CAN databases
