Built for people who read DBC files for a living

CANape and INCA are overkill when you just need to look up a signal. This is the tool for that job.

Message & signal tables

Browse every BO_ block with ID, DLC, cycle time and full signal layout — start bit, length, byte order, factor, offset, min/max.

Intel & Motorola byte order

Both bit-numbering conventions decoded correctly, including extended frames flagged automatically.

Value descriptions

VAL_ enumeration tables shown inline, so 0x1 is 'Gear 1' instead of a mystery number.

Fault-tolerant parsing

Real-world DBC files break parsers. Ours reports malformed lines with line numbers and keeps going — no all-or-nothing failures.

One-click export

Export every signal to Excel, CSV or JSON. Runs entirely client-side; the file never leaves your machine.

Nothing to install

No license server, no dongle, no admin rights. Open the page and drop your file — works on locked-down engineering PCs.

New: short guides to CAN, DBC and A2L

DBC describes the signals inside CAN frames; A2L/ASAP2 describes ECU calibration objects. Both are plain-text databases that our viewers parse locally in your browser, so your files never leave the page.
