Three changes prepare the next tagged release so end users get the PDF Extractor without ever touching pip. **Exact-pin the new deps** (``requirements.txt``): pdfplumber==0.11.9 pypdfium2==5.8.0 pytesseract==0.3.13 streamlit-drawable-canvas==0.9.3 Tight pins are the right call for these because the GUI's visual-picker geometry + the parsing-pipeline word positions depend on stable internal behavior — a quiet upstream tweak to ``extract_words`` or ``page.render`` would re-break the tool on the next CI build. Bumping requires a deliberate edit + a CI run, not a transient ``pip install`` resolving to whatever ``setup.py`` pulled. Existing deps stay on their current ``>=X.Y,<X+1`` ranges; the user's "tight pin" concern is specifically about the PDF stack. **Wire the new deps into the PyInstaller bundle** (``build/``): - ``datatools.spec`` — add ``collect_submodules`` for pdfplumber, pdfminer, pypdfium2, streamlit_drawable_canvas, PIL, pytesseract; add ``collect_data_files`` for pypdfium2 (PDFium native ``.dll``/``.so``/``.dylib``), streamlit_drawable_canvas (frontend JS bundle), pdfminer (Adobe CMap tables). - ``hooks/hook-pypdfium2.py`` — belt-and-braces hook that uses ``collect_dynamic_libs`` to force-include the PDFium binary. Without this the visual picker silently fails on installed builds with a ``FileNotFoundError`` for the shared library. - ``hooks/hook-streamlit_drawable_canvas.py`` — collects the built JS frontend so the canvas iframe loads under the bundled Streamlit server instead of rendering blank. **Tesseract is intentionally NOT bundled** (option A from the design discussion). Modern bank statements are text-based; bundling Tesseract would ~triple installer size for a long-tail case. The in-app banner directs users to install it from ``UB-Mannheim/tesseract`` if they need OCR. Decision is captured in the ``project-pdf-installer-pending`` memory note. **Smoke tests** (``tests/test_pdf_extract_smoke.py``, 17 tests) add the layer above the pure unit tests: - ``TestDependencyImports`` — each dep imports cleanly - ``TestRealPdfRoundTrip`` — generates a tiny statement PDF in memory with ``fpdf2`` (test-only dep in ``requirements-dev.txt``), runs ``extract_pages`` + ``apply_template``, asserts 3 rows out with the right signed amounts. Catches "the build succeeded but pdfplumber breaks at runtime." - ``TestRenderPageImage`` — exercises ``pypdfium2.render`` so the hook-bundled native lib gets a real call. This is the most common installer-bug signature (missing .dll) and the test catches it before users do. - ``TestPdfDependencyMissing`` — monkeypatches ``__import__`` to simulate a stripped install; confirms the typed exception + actionable hint round-trip. - ``TestPinnedVersionsMatchInstalled`` — parametrized over all four pinned dists; uses ``importlib.metadata`` rather than ``__version__`` because pypdfium2 doesn't expose it directly. Trips if someone bumps the pin without reinstalling. - ``TestOcrAvailability`` — confirms ``ocr_available()`` returns ``(bool, str)`` and ``extract_pages_auto(allow_ocr=False)`` skips OCR cleanly. All 81 PDF + audit tests still pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Download (non-technical users)
Pre-built installers — no Python required:
| Platform | Download | First-launch note |
|---|---|---|
| macOS | DataTools-X.Y.Z-mac.dmg |
Drag DataTools.app into /Applications, then double-click. |
| Windows | DataTools-X.Y.Z-win-setup.exe |
Run the installer; launches from Start Menu. |
| Linux | DataTools-X.Y.Z-linux-x86_64.AppImage |
chmod +x the file, then double-click. |
Latest release: see GitHub Releases (or the Gumroad listing). The installers are ~150–200 MB; the launcher boots a local server at http://127.0.0.1:8501 and opens your browser. Nothing is sent to the cloud.
Install from source (developers)
pip install -r requirements.txt
Python 3.10+ required.
Run
GUI (recommended):
streamlit run src/gui/app.py
CLI — seven entry points:
python -m src.cli customers.csv [--apply] # dedup
python -m src.cli_text_clean messy.csv [--apply] # text clean
python -m src.cli_format intl.csv [--apply] # format standardize (auto-streams >100 MB)
python -m src.cli_missing holes.csv [--apply] # missing values
python -m src.cli_column_map vendor.csv [--apply] # column mapper
python -m src.cli_pipeline any_file.csv [--apply] # chain tools end-to-end
python -m src.cli_analyze any_file.csv [--json] # scan only
Every CLI runs preview-only by default; add --apply to write output.
Language
The GUI sidebar has a language picker. Packs ship for English and Español (src/i18n/packs/); the choice persists for the session. Adding a language: drop a <code>.json next to en.json mirroring its key tree, then list it in LANGUAGES. See Developer Guide §i18n.
Review & Normalize gate
Every uploaded file passes through a CSV-normalization gate before any tool sees it. The analyzer flags ~15 issue types (whitespace, NBSP / zero-width chars, BOM, encoding, smart punct, dirty headers, null sentinels, mojibake, …) tagged by confidence (high / medium / low) and fix action. The GUI shows each finding with Auto-fix / Skip / Customize, a live before/after preview, and an encoding-override picker. Tool pages refuse to load until the gate passes.
Output
Every run writes:
{input}_<tool>.csv— the cleaned data{input}_changes.csv(text cleaner) or{input}_match_groups.csv(dedup) — audit traillogs/<tool>_YYYYMMDD_HHMMSS.log— debug-level run log
Original input file is never modified.
