The bundled docx, xlsx, powerpoint, and pdf skills were adapted from Anthropic's document skills and carried their proprietary LICENSE.txt (no derivatives, no redistribution). Flagged as critical license findings by the SkillEvaluator Tier 1 scan of our skill tree. This replaces all four with clean-room rewrites: - Authored from scratch against library knowledge only (python-docx, openpyxl, python-pptx, pypdf/reportlab/pdfplumber — all MIT/BSD) by isolated subagents given functional specs, with an explicit prohibition on reading the prior skill content or anthropics/skills; session transcripts retained as provenance evidence. - MIT licensed (LICENSE file per skill), author: Nous Research. - Each skill: SKILL.md to house standards + argparse helper scripts with UTF-8-explicit I/O + its own e2e pytest suite (fixtures built on the fly, non-ASCII round-trips run under LC_ALL=C). - All four pass SkillEvaluator Tier 1 pii+unicode+lint 3/3. tests/skills/test_office_document_skills.py rewritten against the new contracts: MIT/no-Anthropic-text invariants, scripts documented in SKILL.md, argparse CLI shape, and a no-locale-default-open() check (which caught and fixed a real gap: pdfplumber text reads are fine, but the invariant scan now guards every future script). Docs pages regenerated for the four skills (scoped; unrelated generator drift excluded). Honest capability deltas vs the old versions are documented per SKILL.md (e.g. tracked-changes accept/reject and OOXML XSD validation are not reimplemented; form flattening limits stated).

"""Export one sheet of an .xlsx workbook to CSV.
|
|
|
|
Dates/datetimes are written in ISO format; None becomes an empty field.
|
|
With --data-only, formula cells yield their cached results (present only
|
|
if the file was last saved by Excel/LibreOffice; openpyxl never computes).
|
|
|
|
Usage:
|
|
xlsx_to_csv.py book.xlsx out.csv
|
|
xlsx_to_csv.py book.xlsx out.csv --sheet Data --encoding utf-8-sig
|
|
xlsx_to_csv.py book.xlsx out.csv --delimiter ';' --data-only
