About this gig

Turn repetitive CSV work into a reusable Python tool.


The basic package covers up to 2 input CSV formats, 20 columns per format, 10,000 rows per run, and 3 agreed transformation or validation rules. Examples include merging files, removing exact duplicates, normalizing dates, and flagging missing values.


You receive readable Python source code, a run guide, sample input/output, and a validation report. Original files remain unchanged. I check row counts, identifiers, and the agreed output against your sample. Includes one revision within the agreed scope and 5-day delivery after complete requirements.


Please message with a redacted sample and expected output before ordering. This is AI-assisted development. Only share data you are authorized to provide and agree may be processed with AI assistance.


Communication and delivery use Fiverr messages and files, with AI-assisted written English support. Live meetings, web scraping, account access, hosting, OCR, and ongoing maintenance are not included. New requirements require a separate quote.

Hi, I'm Leon. I build Excel sales dashboards, responsive enquiry pages and small automation tools for business workflows. Services include monthly and product reporting, CSV processing and scoped API or webhook integrations. You receive editable files or source code, clear instructions and checks against the agreed requirements. My portfolio uses original fictional demos, not client results. I work with AI assistance and communicate through Fiverr messages in Korean or AI-assisted written English. Send a redacted sample and your desired outcome before ordering.
