pandas + numpy were ~60MB of the shipped venv for three call sites (alarm Excel import, managed-NE import, import template). netx_api/tabular.py reads/writes xlsx and csv and parses spreadsheet timestamps. Checked against the pandas version on the same inputs: timestamp parsing identical for 24 formats, managed-NE csv/xlsx import, stored rows and both templates identical. Differences, all fixes: - alarm codes in mixed text/number columns are "1001", not "1001.0" - error row numbers are the real sheet rows (blank rows no longer shift them) - GBK-encoded CSVs (Chinese Excel "Save as CSV") import instead of failing - "2024年1月2日 03:04:05" style timestamps parse Also: conftest compares parsed DB URLs (newer SQLAlchemy renders "C:" as "C%3A").
