Data Extraction Expert

Need clean, reliable data from websites, APIs, PDFs, or spreadsheets? I build and maintain Python scraping and data extraction workflows that turn difficult sources into validated CSV, Excel, JSON, Google Sheets, or database-ready data. Top Rated Plus | 100% Job Success | $90K+ earned | 3,600+ Upwork hours Since 2019, I have worked on both one-time extractions and long-term data collection systems.

I can help you with: • Static and JavaScript-rendered websites using Scrapy, Playwright, Selenium, Requests, BeautifulSoup, and lxml • API discovery and integration, including extracting structured data from network requests • PDF and document extraction using pdfplumber, PyMuPDF, OCR, and AI-assisted extraction with human validation • Data cleaning, normalization, deduplication, validation, and transformation with pandas • CSV, Excel, JSON, XML, Google Sheets, SQL, and MongoDB output • Pagination, interactive search forms, file downloads, browser workflows, and session management • Reliable logging, retries, error handling, rate limiting, and failure tracking • Scheduled and recurring data collection workflows • Repairing and updating existing scrapers when websites or document formats change What you receive: • Clean and consistently structured data • Reusable and maintainable Python code • Validation against the original sources • Clear source URLs and traceable outputs when required • Documentation and straightforward communication • Missing or uncertain records clearly flagged instead of guessed or fabricated If your source is dynamic, document-heavy, inconsistent, or regularly changing, send me the URLs or files, required fields, preferred output format, and whether the extraction is one-time or recurring.
