sn-da-large-file-analysis
万行以上 Excel 数据集的高性能分析引擎。提供 openpyxl read_only 流式读取（iter_rows 支持 10 万行以上）、Parquet 转换加速、内存优化、分块处理和大文件写入模式。**遇到以下任一情况就主动使用本 skill**：①数据行数 ≥ 10k（由 sn-da-excel-workflow 的行数评估步骤触发）；②用户出现触发词：大文件 / 大数据量 / 性能优化 / 内存不足 / OOM / 百万行 / 十万行 / 流式读取 / Parquet / 分块处理 / large file / big data / streaming read / chunked processing；③直接使用 pd.read_excel() 导致超时或内存溢出；④用户明确要求对大规模数据集进行高性能处理。仅不用于：小于 10k 行的常规 Excel 分析（使用 sn-da-excel-workflow 即可）。

Source changelog
sn-da-large-file-analysis 2026.8.19 - Completely rewritten and expanded documentation in SKILL.md with full method explanations, code snippets, and strict usage rules. - Enforces mandatory use for Excel files with ≥10,000 rows and provides clear prohibited operations for large-scale processing. - Introduces high-performance techniques: streaming reads with openpyxl, chunked Parquet export, and automatic memory/type optimizations. - Step-by-step guidance for environment setup, font configuration (no font searches), and efficient large file writing/export strategies. - Designed to seamlessly optimize large Excel datasets; not triggered for small (<10k rows) files.
