type:audit

Profile, clean, standardize, transform, fill, or deduplicate spreadsheet or delimited data into an authorized new output with traceable rules, before/after statistics, an audit log, and validation of formulas, encoding, dimensions, and key summaries. Do not overwrite source data, guess critical values, or delete plausible records, and degrade to a cleaning plan when execution tools are unavailable. Use excel-data-quality-check-basic instead when the user requests only a read-only data-quality audit or issue report without changes or a cleaned copy. 对电子表格或分隔数据进行画像、清洗、标准化、转换、填补或去重，并在用户授权下生成新结果，提供可追踪规则、前后统计、审计日志及公式、编码、行列数和关键汇总验证。不得覆盖原始数据、猜测关键值或删除可能有效的记录；缺少执行工具时降级为清洗计划。用户只要求只读数据质量审计或问题报告，不要求修改或清洗副本时，应使用 excel-data-quality-check-basic。
