I will automate CSV merging cleanup and validation with python
About this Gig
Stop combining the same CSV exports by hand. I will build a reusable Python script for one clearly defined CSV workflow.
Included: up to 5 input CSV files with the same column structure, up to 5 agreed cleanup or validation rules, clean CSV output, a separate review log, source code and run instructions. Examples: trim spaces, check required fields, validate numbers, remove exact duplicates and flag conflicting IDs.
The script runs locally and leaves your input files unchanged. Conflicting records are reported for your review, not silently overwritten. Python 3.10+ is required.
My gallery shows CSV Desk, a self-initiated demo using synthetic data, not a paid client result.
Before ordering, send an anonymized sample, the desired output and your operating system. We will confirm file size, rules and acceptance criteria. One revision covers the agreed workflow.
Not included: XLSX workbooks, API/CRM connections, web scraping, scheduling, hosting, a standalone EXE or complex desktop UI. These need a separate scope.

FAQ
Can I run the script again on new exports?
Yes, if the files keep the agreed column structure and rules. You receive Python source code and instructions. Python 3.10+ is required; a standalone EXE is not included.
