About this Gig

Repeated CSV rows? Get a checked file and a clear record of what was removed.


One UTF-8 CSV: up to 100 data rows, 20 columns and 2 MiB. Choose comma, semicolon or tab as delimiter.


A tested local automated workflow removes only rows whose cells match an earlier row exactly, keeping the first occurrence. Spacing, case and values stay unchanged. Blank cells are flagged. Leading zeros remain in the CSV text; import codes as text in your spreadsheet.


You receive a ZIP: unchanged original, result, removed rows, readable report, source-line references and checksums.


Delivery: 4 days. One correction on the same source and agreed rule is included.


No XLSX, PDF, fuzzy matching, formula evaluation or business-data corrections. Malformed files, ambiguous headers and potential formulas require review before processing. No third-party import guarantee.


Please confirm compatibility before ordering. Only non-personal or anonymized data is accepted. Files are processed locally, not sent to an AI model or used for training. Fiverr handles attachments under its own policies.
