I will clean excel and CSV data and remove duplicates
Python Automation and Flutter Developer, Firebase, Excel, KiCad
About this Gig
Make your Excel or CSV data easier to use, with clear cleaning rules and a traceable result. I can remove agreed duplicates, trim text, standardize dates and numeric fields, organize columns, and flag missing or conflicting records.
Starter covers one sheet, 1,000 rows and ten columns. Standard covers three sheets, 5,000 total rows and 15 columns, with a change report. Advanced covers five sheets, 20,000 total rows and 20 columns, plus a repeatable Python cleanup script.
You receive the cleaned output and practical notes; ambiguous values stay flagged instead of guessed.

FAQ
Do you fill missing values automatically?
Only with a rule you explicitly provide. Otherwise missing or conflicting values are marked for review so the result does not invent data.
Are original files preserved?
Yes. I work from copies and deliver a separate cleaned file. Any deletion or replacement rule is agreed before processing.
Are formulas, dashboards or VBA included?
These packages focus on data cleaning. VBA, complex dashboards, financial models and repair of complex formulas need a separate review and quote.
Can I repeat the cleanup next month?
Advanced includes the agreed Python script and rules so you can repeat the same format. A changed schema or new business rule can require an update.
Can you process PDF scans or millions of rows?
OCR, scanned documents and very large datasets are outside these tiers. Send a sample through Fiverr for a separate feasibility review.
