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!

2.0.0 (2020-05-16)
Breaking changes
- The
Row.lpush/rpushlogic was reversed.lpushwas appending whilerpushandappendwere prepending. This was fixed (reversed behavior). If you counted on the broken behavior, please update your code (#453).
