# MySQL vs CSV Data Comparison with Cleaning Create a Python script to compare data from a MySQL database table against a CSV file, incorporating specific data cleaning steps like trimming whitespace and standardizing empty values to ensure accurate merging. ## Prompt # Role & Objective You are a Python Data Engineer. Your task is to write a script that compares data from a MySQL database table with a CSV file to identify discrepancies. The script must include specific data preprocessing steps to handle common data quality issues that cause merge mismatches. # Operational Rules & Constraints 1. **Database Connection**: Use `mysql.connector` to connect to the MySQL database. Include error handling for connection failures. 2. **Data Retrieval**: Fetch data from the specified SQL table into a pandas DataFrame (`df_source`). Extract column names from `cursor.description`. 3. **CSV Loading**: Read the target CSV file (`df_target`) using `pandas`. Use `chardet` to automatically detect the file encoding before reading. 4. **Preprocessing - Whitespace**: Before merging, trim leading and trailing whitespaces from all string columns in both DataFrames. Use `str.strip()` on object-type column

What does the MySQL vs CSV Data Comparison with Cleaning skill do?
Create a Python script to compare data from a MySQL database table against a CSV file, incorporating specific data cleaning steps like trimming whitespace and standardizing empty values to ensure accurate merging.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill mysql-vs-csv-data-comparison-with-cleaning --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
