Here's a Python library to parse ANT/Garmin .FIT files.

Welcome to python-fitparse! After a few years of laying dormant we are back to active development! The old version is archived as v1-archive.

The FIT (Flexible and Interoperable Data Transfer) file protocol is specified by ANT (http://www.thisisant.com/) and an SDK is available for download at http://www.thisisant.com/pages/products/fit-sdk.

• New, hopefully cleaner public API with a clear division between accessible and internal parts. (Still unstable and partially complete.)

• Proper documentation! Available here.

• Unit tests and example programs.

• (WIP) Command line tools (eg a .FIT to .CSV converter).

• Component fields and compressed timestamp headers now supported and not just an afterthought. Closes issues #6 and #7.

• FIT file parsing is generic enough to support all types. Going to have specific FitFile subclasses for more popular file types like activities.

• (WIP) Converting field types to normalized values (for example, bool, date_time, etc) done in a consistent way, that's easy to customize by subclassing the converter class. I'm going to use something like the Django form-style convert_<field name> idiom on this class.

• The FIT profile is its own complete python module, rather than using profile.def.

  • Bonus! The profile generation script is less ugly (but still an atrocity) and supports every ANT FIT SDK from version 1.00 up to 5.10.

• A working setup.py module. Closes issue #2, finally! I'll upload the package to PyPI when it's done.

• Support for parsing one record at a time. This can be done using <FitFile>.parse_one() for now, but I'm not sure of the exact implementation yet.
