I will write a small python script to automate CSV and file tasks

Save repeated manual work with a small, clearly scoped Python utility. This package covers ONE operation: trim outer whitespace in a CSV, remove exact duplicate CSV rows, OR create a read-only file inventory. One local workflow, one operating system, up to 10 local files with the same schema, and 10000 total CSV rows/20 columns. You receive readable source code, setup instructions and tests using representative sample data. Please send a sanitized sample input and the exact expected output before ordering. Scripts create separate outputs and use standard Python libraries where practical. No hosting, APIs, scraping, login automation, desktop GUI, deployment or ongoing monitoring is included. Existing-code debugging and additional operations require a separate review. One revision covers corrections within the original agreed rules. Gallery examples show a tested demonstration, not a client project.
