tui

Interactive terminal UI for exploring a sample of a dataset (not the whole file). Requires pip install "undatum[tui]" and a real TTY.

pip install "undatum[tui]"
undatum tui data.csv
undatum tui data.parquet --limit 500
undatum tui workbook.xlsx --table Sheet2
undatum tui nested.jsonl --flatten-nested

Keys: q quit, ? help, o open, s profile, f frequency on the selected column, / filter the sample, e export the current view, w convert/save as (full file, --low-memory), v validate the sample, m mask preview, p export pipeline YAML, : command palette, ctrl+s SQL (default LIMIT 500 on the data view), Tab cycle panes. From the file picker, u opens a local path or s3:// / gs:// / az:// URI. The status line shows the equivalent CLI command. Recent files are stored as paths only in ~/.undatum/tui-history.json. Use table / profile / sql when you are not on an interactive terminal.
