I will clean, format and deduplicate messy excel or CSV spreadsheet data
Data cleanup, PDF forms and practical quote calculators
About this Gig
Send a 5-row CSV or Excel excerpt in chat for a free cleaned and deduplicated preview before ordering. I fix messy spreadsheets, CRM exports and CSV files.
Basic covers one UTF-8 CSV export from Excel, Shopify, Stripe or your CRM, up to 5,000 data rows and 30 columns with 24-hour delivery. I trim selected text columns, lowercase selected columns and remove whole rows that become identical after cleanup. The first source row is kept and every removal is logged.
You receive the cleaned UTF-8 CSV, cell-change and duplicate reports, a visual HTML audit summary and an Excel import guide. Product SKUs, leading zeros, blanks, quoted commas and line breaks stay intact. Set identifier columns to Text when opening in Excel so leading zeros stay preserved.
Scope: no missing-value guesses, fuzzy matching, data enrichment, multi-file joins, macros or live database access. Cells a spreadsheet might treat as formulas are flagged for review first.
One consolidated revision covers the approved file and rules within these limits. I correct my own processing errors. I am based in the UK.
FAQ
Can I see a sample on my file before ordering?
Yes. Send a 5-row CSV excerpt and your cleanup rules in Fiverr chat. I will return a free watermarked before-and-after preview so you can confirm the fit before placing an order.
How many rows does the Basic package cover?
Up to 5,000 data rows and 30 columns in one CSV or Excel file, delivered within 24 hours. Message me before ordering if you have a larger file.
Will leading zeros stay intact in Excel?
Yes, identifiers stay literal text in the delivered CSV. Set identifier columns to Text in Excel's import wizard so automatic number conversion does not strip leading zeros.
What files are included in the delivery?
A cleaned UTF-8 CSV, JSON change and duplicate reports, a visual HTML audit summary showing every cell edit, and an import guide.
Do you use AI?
Deterministic local code transforms the file. AI can help with planning and review if you permit it. Confidential files are never uploaded to an external AI provider without separate permission.
What does the revision cover?
One consolidated revision within the approved file, rules and size limits. New files or different matching rules need a new scope. I correct my own processing errors.
