- Worth noticing
- The joblib inspector is checked against 33 files across 14 pinned Python environments, with 70 recorded load results.
Field notes
The tools cover several formats that can be awkward to open without their original software, including Access databases and older scikit-learn joblib files. The testing notes distinguish between independent comparisons and automated browser tests: the Parquet Viewer and Map Image Export have browser tests but no lab yet. The page also provides a suggested Network-tab check for its claim that files are not uploaded.
