I am attaching the screenshot First file error second file error. The first has incompatible header whereas your table contains spaces in the cell, where canmatrix expects CAN ID (ID in the header). It must either contain valid hexadecimal CAN ID ended by xh or empty cell (really empty, not containing spaces not visible by eyes). I had checked your suggestion the test.xlsx can be transformed to dbc file, but the dbc file cant open. How can we use this Actually this extend mode and normal mode doesnt be combined in one DBC. You can safely mix standard and extended ids in single file. If we were to apply this to the creation and transmission of CAN frames, we world just reverse our thinking and reverse the order of operations. For any given CAN ID, a DBC file can identify some or all of the data within the CAN frame. The data in a CAN frame can be broken up into eight one-byte values, sixty-four one-bit values, one sixty-four bit value, or any combination of these, and a DBC file can be used to identify, scale, and offset the data represented by any or all of these values. When working with CAN data, its never long before the subject of the DBC file is introduced, because this is the most common way to handle identification and translation of the data. Specifically, Im referring to the identification of CAN messages and the translation of the raw CAN data, as transmitted within a CAN frame, to meaningful values and meaningful information. Similar standards operate for other bus systems, such as FIBEX database files (.xml) for FlexRay and LDF for LIN (.ldf). In fact, I recently scanned most of the SAE J1939 standards documents and neither the terms DBC nor database, in the context of the DBC file, appeared in any of the documents. Although the word database is used in many other places and in many other contexts, when used in connection with CAN data, its probably referring to the DBC file. The Standards Committee assigns many identifiers, names, numbers and formats that are represented in a DBC file, but the file itself is not a product of the SAE. SAE maintains and sells a Windows Excel file that is used to communicate the technical information needed to create a J1939 DBC file. This Excel file is called J1939DA, or Digital Annex, and can be purchased at the SAE web site here. If your product only needs to understand a few of the messages within the SAE J1939 standard, then your DBC file only needs to define the messages your product needs to understand, and all other messages do not need to be defined in your DBC file. ![]() Convert Dbc File To Excel Programs Free Kvaser DatabaseOne easy option for viewing and editing a DBC file is the free Kvaser Database Editor 3 available for download here. ![]() Its common to have two or more DBC files associated with one CAN bus monitoring application in order to define the different data within that application. Its also common to see messages on complicated CAN networks that are not defined by any of the associated DBC files, and in this case the messages will usually be displayed by the application as raw CAN data. As such, the Society expends considerable resources maintaining and protecting its rights to its intellectual property. I am not a lawyer, so I recommend you review the SAE Terms and Conditions with a lawyer before you resell anything that could be considered SAE Intellectual Property.

Convert Dbc File To Excel Programs How To Separate TheThis is an article directed at understanding the DBC file, so Im not going to go into great details regarding the CAN frame, other than to show how to separate the identifier from the data. Here is an example of a typical CAN frame with a 29-bit identifier and eight bytes of data, as represented within CANKing. For those of you who want to understand more, the identifier contains the Priority, Parameter Group Number (PGN), and Source Address (SA) of the message. The DBC file provides the information needed for the application to understand the data, take the data apart, apply a scale and offset, label the data, and interpret it. This explanation is being presented from the point of view of receiving data.
