🤖 AI Summary
This work addresses the significant limitations of spreadsheet-based analysis in reproducibility, auditability, version control, and automation. It proposes a migration pathway from Excel to research-grade analytical workflows by leveraging Python’s pandas library as a bridge. The study introduces an innovative set of Excel-to-pandas mapping rules, categorizes nine canonical workflow patterns, and compiles a catalog of common failure modes. Seven end-to-end real-world examples demonstrate the approach in practice. By retaining Excel as a familiar interface for input and output while integrating version control, automated refreshing, and seamless incorporation of statistical and machine learning methods, the proposed framework enables governed, reproducible, and auditable tabular data analysis.
📝 Abstract
Spreadsheet-heavy analytical work remains common in business analytics, operations reporting, and applied research, yet workbooks that grow through formulas, manual edits, and copy-paste refresh are difficult to audit, reproduce, and govern at scale. When tabular work requires repeatability, validation, version control, automated refresh, or integration with statistics and machine learning, analysts need a transformation layer that preserves familiar table concepts while making assumptions explicit. This paper treats the Python pandas library as that layer: a practical bridge between spreadsheet practice and research-grade workflows, not a wholesale replacement for Excel. The paper contributes an Excel-to-pandas migration mapping, a taxonomy of nine workflow categories, seven end-to-end examples drawn from business analytics and applied research, a failure-mode catalog, and reusable code recipes for governed tabular work. pandas is most useful when tabular analysis must be repeatable, auditable, and defensible, while Excel can remain a familiar input and output interface for stakeholders who need workbooks.
