SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill solves the problem of unstructured or noisy text inside large multi-sheet Excel files by cleaning it into standardized Chinese-only values and then producing reliable counts for a dynamically detected target column.

Core Features & Use Cases

  • Multisheet Excel Text Cleaning: Applies regex-based extraction to keep only Chinese characters in specified text fields, reducing formatting noise and improving downstream analysis quality.
  • Dynamic Column Matching + Counting: Automatically finds the target column by keyword (case-insensitive, tolerant of column naming variations) and counts matching values to generate summary statistics.
  • Cleaned Output Export: Saves the cleaned dataset to a standardized Excel file and reports the resulting file size and a download link.

Use Case: You receive an Excel report with many sheets where a field like recipient/type contains mixed language, numbers, and symbols; use this Skill to clean the field to Chinese-only, locate the relevant “type” column, count how many rows match a specific value (e.g., "varchar"), and export a cleaned Excel for reporting.

Quick Start

Ask the Excel workflow to process the uploaded multi-sheet file, clean the designated text column to Chinese-only characters, dynamically identify the column containing a given keyword, count occurrences of a specified value, and export the cleaned Excel output.

How do I clean messy Chinese text in multi-sheet Excel files?

To clean messy Chinese text in multi-sheet Excel files, this Skill applies regex-based extraction to remove formatting noise, keeping only standardized Chinese characters in specified text fields for improved downstream analysis.

How do I count occurrences of a specific value in an Excel column with inconsistent naming?

To count occurrences of a specific value in an Excel column with inconsistent naming, this Skill uses case-insensitive fuzzy column detection to automatically locate the target column by keyword and generates summary statistics for matching rows.

Can I automatically extract Chinese characters and export a cleaned Excel file for reporting?

Yes, you can automatically extract Chinese characters and export a cleaned Excel file for reporting. This Skill processes multi-sheet files, normalizes text fields, and outputs a standardized dataset with file size reporting and a download link.

What is the best way to preprocess large Excel files before data summarization?

The best way to preprocess large Excel files before data summarization is to apply regex-based text normalization and dynamic column matching. This Skill cleans noisy schema variances and counts key values to prepare standardized data.

Does this Excel text cleaning tool handle schema variance across multiple sheets?

Yes, this Excel text cleaning tool handles schema variance across multiple sheets by applying case-insensitive fuzzy column detection. It tolerates column naming variations to reliably locate target fields and count specified values.
