You will get a tested Excel or CSV reconciliation tool with an exception report
Project details
Turn two spreadsheet exports into one review-ready difference report.
I will configure a local Python reconciliation tool for your approved CSV or Excel templates. It matches rows by the key columns you define, compares the fields that matter, and separates the result into matched, changed, left-only, right-only, duplicate-key, and invalid-key records.
You receive the source code, automated tests, setup instructions, a machine-readable JSON result, an exception-only CSV, and an Excel workbook with a summary plus separate review tabs. Changed records preserve both source values, original row numbers, and the exact fields that differ.
This is a fixed-scope file comparison tool, not accounting approval, fraud detection, live ERP synchronization, or data-entry outsourcing. I work from sanitized sample files and do not need credentials for your bank, database, or private systems. CSV and XLSX files are supported within the row limit of the selected package.

Frequently asked questions
About Jeeyong
Backend Automation Developer | APIs, Bots & Integrations
Seoul, South Korea - 3:21 am local time
I can help with:
• REST API integrations and data normalization
• scheduled jobs, monitoring, and change detection
• workflow automation and notification bots
• Python and TypeScript implementation
• small backend bug fixes and test coverage
• setup instructions, Docker-ready delivery, and reproducible demos
Recent public work includes a governance-monitoring integration that retrieves proposal data from a public API, formats exact results, and delivers notifications through Telegram, with a public GitHub pull request and recorded demo.
I keep projects narrow and verifiable: requirements first, code and tests second, then a clear handoff. I do not need your production credentials; secret values can be added by you after delivery.
Good fit:
• connect a public API to an existing workflow
• automate a repetitive data task
• build a scheduled monitor or notification bot
• fix and test a small backend component
• add setup documentation to a public repository
AI tools may assist development, but I verify the implementation, tests, and stated results before delivery.
