SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes inconsistencies in Excel numeric columns and prevents incorrect reporting by normalizing number formats, summing cleaned values, and cross-checking them against a provided “合计” row.

Core Features & Use Cases

  • Numeric cleaning & normalization: Drops empty values in the target column and coerces values into a proper numeric type for reliable aggregation.
  • Sum reconciliation against a reference sheet: Reads a specified sheet and compares the calculated total with the expected “合 计” item value using a small tolerance for floating-point differences.
  • Exportable results: Writes a summary table to both Excel and CSV, including calculated totals, expected totals, consistency status, and the difference.

Quick Start

Ask to normalize the target numeric column in your Excel file, verify its total against the “合 计” row in the Summary sheet, and export the reconciliation results to analysis_result.xlsx and analysis_result.csv.

FAQPage Schema
How do I normalize numeric columns in Excel for accurate aggregation?

To normalize Excel numeric columns, the Skill drops empty values and coerces data into proper numeric types. This ensures accurate aggregation by preventing text-formatted numbers from skewing your calculated totals.

How do I verify Excel totals against a reference sheet?

Excel total verification is done by loading an expected total from a specified sheet and comparing it with your calculated sum. The Skill checks these values against a numeric tolerance to handle floating-point differences.

What is the best way to reconcile computed totals with a reference row in Excel?

The best way to reconcile Excel totals is to compute the cleaned sum of normalized numeric columns and compare it against a reference item value. This process identifies inconsistencies and verifies data accuracy within a set tolerance.

Can I export data cleaning and reconciliation results to both XLSX and CSV?

Yes, you can export reconciliation outputs to both XLSX and CSV formats. The export contains a summary table detailing calculated totals, expected totals, consistency status, and the numeric difference.

Why does my Excel sum not match the expected total after data cleaning?

Your Excel sum may not match due to null values or text-formatted numbers causing incorrect aggregation. Normalizing numeric columns by coercing values ensures the computed sum accurately reflects the underlying data.

Does numeric normalization in Excel handle floating-point differences during total reconciliation?

Numeric normalization handles floating-point differences by applying a small numeric tolerance during total reconciliation. This ensures the computed sum and the expected reference value match without failing on minor precision errors.
