load data, filter it, export it. that's it.
a desktop data viewer. open a file, see it in a table, filter columns with commands, sort by clicking headers, export what you need. supports csv, tsv, json, and xlsx.
type these in the per-column filter inputs. prefix with #. without a prefix it does a case-insensitive substring search.

python main.pyrequires python 3.9+.
you can also drag and drop files directly onto the window.
for windows release zips, extract the entire archive first and run
DART\\DART.exe from the extracted folder (do not run directly from inside the zip).
pyside6 for the ui. chardet for encoding detection. openpyxl for excel files. delimiter auto-detection via python's csv sniffer. everything runs locally, nothing leaves your machine.
the codebase is split into modules: app.py (main window), theme.py (colors + stylesheet), filter_model.py (filter logic), dialogs.py (about, help, stats), widgets.py (filter bar, search, overlays), splash.py (startup screen). main.py is just the entry point.
push a tag and github actions builds standalone bundles for macos and windows via pyinstaller. artifacts are uploaded to the release.
