You will get recurring Excel and CSV file processing and reporting automation
Project details
Still copying, cleaning, merging, and rebuilding the same Excel or CSV reports every day, week, or month?
I will turn your repetitive spreadsheet work into a reusable file-processing pipeline. Instead of manually opening files, copying rows, fixing formats, updating formulas, removing duplicates, and rebuilding reports, you can add new files to an agreed folder and run or refresh the workflow.
The automation can combine Excel or CSV files, process newly added files only, standardize columns, dates, numbers and text, clean and filter rows, remove duplicates, create calculated columns, map known column variations, join datasets, detect missing or invalid values, and produce validation or exception reports.
Depending on your package, the output can include a clean master Excel or CSV file, processing log, exception sheet, KPI or summary workbook, and optional PDF-ready report.
I can use Python, Pandas, Excel Power Query, or a suitable combination. Once configured, future files that follow the agreed structures can be processed with the same rules.
This helps finance, operations, sales, inventory, reporting, and research teams run recurring spreadsheet work reliably.

Frequently asked questions
About Biwan
Software Developer | Automation, Data Extraction & React Native
Beijing, China - 12:55 pm local time
I help businesses reduce repetitive manual work by turning documents, spreadsheets, and browser-based processes into reliable and maintainable workflows. I also build fast, stable, and user-friendly mobile applications for iOS and Android using a shared React Native codebase.
What I can help you with:
• Document data extraction: Convert invoices, receipts, PDFs, scans, and images into clean Excel or CSV files.
• Excel and CSV automation: Clean, merge, transform, validate, deduplicate, and restructure business data.
• Browser automation: Automate repetitive web tasks, data entry, form submissions, downloads, file uploads, and reporting workflows.
• Custom scripts and tools: Build reusable solutions for file processing, document generation, deployment, reporting, and operational tasks.
• React Native development: UI implementation, state management, API integration, authentication, real-time data, file handling, native device features, and performance optimization.
• Frontend development: Build responsive and maintainable interfaces using modern JavaScript, TypeScript, React, and related technologies.
Why clients work with me:
• Practical solutions focused on clear business outcomes.
• Strong problem-solving skills and careful attention to edge cases.
• Clean, maintainable code instead of fragile one-off fixes.
• Careful validation when processing documents and structured data.
• Clear and proactive communication throughout the project.
• Flexible and efficient when working with new tools, libraries, platforms, and requirements.
Whether you need a one-time data processing task, a reusable automation workflow, a browser automation tool, or a production-ready mobile application, I can turn your requirements into a reliable solution.
