Send me your messy CSV or Excel export (contacts, leads, customers, products) and get back a clean, ready-to-import file.

**What you get in the basic package (up to 10,000 rows):**
- Duplicates removed by the rule you choose (email, phone, or name + company), with a log of what was merged
- Emails and phone numbers checked and normalised to one format
- Names, dates and columns tidied: extra spaces, wrong case, split or merged fields
- A separate sheet with the rows that need your attention, so nothing is silently deleted
- The result in CSV and Excel, plus a short report with before/after counts

**How it works:**
1. You send the file and tell me which columns define a duplicate.
2. I send a small cleaned sample for you to check the rules.
3. After your approval I clean the full file and deliver it with the report.

Larger files or custom rules: message me first and I will tell you the price before you order.

I build small, reliable automation tools in Python. What I do: Telegram bots (aiogram): FAQ menus, lead forms with phone validation, admin notifications, export to Excel or Google Sheets. Web scraping: product catalogues, prices, public contacts into a clean CSV or spreadsheet. Data cleanup: deduplicate lists, normalise phones and emails, merge files, automated reports. Small web apps and APIs: Flask / FastAPI, simple CRMs on Next.js, WordPress fixes. Transcription and document formatting (Word, PDF), English and Russian. How I work: I confirm the inputs and a sample result with you first, then deliver tested code with a short run guide. Clear scope, fixed price, on-time delivery.
