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.

Vector and ETAS are excellent toolchains — if you need the full suite. For looking up, searching and previewing a file, the browser is enough.
Drop a file. See everything. Pay nothing.
Everything available today is free. Full export and batch features are on the roadmap.
