Tablib is a format-agnostic tabular dataset library, written in Python.

Output formats supported:

  • Excel (Sets + Books)
  • JSON (Sets + Books)
  • YAML (Sets + Books)
  • Pandas DataFrames (Sets)
  • HTML (Sets)
  • Jira (Sets)
  • TSV (Sets)
  • ODS (Sets)
  • CSV (Sets)
  • DBF (Sets)

Note that tablib purposefully excludes XML support. It always will. (Note: This is a joke. Pull requests are welcome.)

Tablib documentation is graciously hosted on https://tablib.readthedocs.io

It is also available in the docs directory of the source distribution.

Make sure to check out Tablib on PyPI!

Breaking changes

Improvements

  • Formats can now be dynamically registered through the tablib.formats.registry.refister API (#256).
  • Tablib methods expecting data input (detect_format, import_set, Dataset.load, Databook.load) now accepts file-like objects in addition to raw strings and bytestrings (#440).

Bugfixes

  • Fixed a crash when exporting an empty string with the ReST format (#368)
  • Error cells from imported .xls files contain now the error string (#202)
