Fixes #2502.
PowerPoint charts grouped by year and quarter currently emit repeated
Q1rows without the years. Read python-pptx'sflattened_labelsand retain the parent-to-child path in the Category cell (2024 / Q1), preserving row order and series values. Flat text and numeric categories keep their existing output.The new tests save real PPTX files in memory and convert them through
MarkItDown.convert_stream. They cover unequal parent group sizes, two and three category levels, multiple series, and flat categories. The two hierarchical cases fail on main; all 21 selected PPTX tests pass with the fix, including existing chart title, multi-series, notes, and image tests. Updated the two chart-title mocks to expose the category API now used by the converter.Validation:
pytest packages/markitdown/tests/test_pptx_*.py packages/markitdown/tests/test_module_misc.py -k pptx -q(21 passed); Black andgit diff --check. No new dependencies or binary fixtures. The full multi-format suite was not run.Prepared with AI assistance; the reproduction and tests were run locally.
