Convert A2L to Excel online
An .a2l file describes the calibration and measurement interface of an ECU: characteristics, measurements, conversion methods and group trees. Drop your file below and export a flat, reviewable spreadsheet — with addresses, data types, conversion formulas and units — all parsed locally in your browser.
- CHARACTERISTIC and MEASUREMENT rows with address, type and conversion method
- COMPU_METHOD format strings and units resolved onto each row
- GROUP tree preserved as a Group column — review by function
- UTF-8 safe for German and Chinese long identifiers
How it works
- 1Open the A2L viewer and drop your .a2l file.
- 2Browse the group tree and record table; search by name or address.
- 3Click Export and choose Excel (XLSX) — generated locally, downloaded immediately.
Frequently asked questions
Does it support ASAP2 (ASAM MCD-2 MC) keyword variants?
The parser follows the standard A2L block grammar and tolerates vendor extensions: unknown blocks are skipped safely instead of aborting, and issues are listed in the diagnostics panel.
Are large A2L files (100k+ records) supported?
Parsing runs in a Web Worker and the table uses virtual scrolling, so files with hundreds of thousands of records stay responsive.
Is the export free?
Everything available today is free to use; there is currently no paid product. The current preview exports the first 20 rows. Full export and batch conversion will be available when Pro launches.
Your file never leaves your browser
CANpeek parses DBC and A2L files entirely client-side — there is no upload step, no account, and nothing stored. There is currently no paid product; full export is planned for Pro.
