I will remove duplicate rows and validate your CSV data
About this Gig
- Get a CSV with exact duplicate rows removed, plus a short validation report with input, retained and removed row counts and structural issues.
I compare the entire parsed row, keep its first occurrence and preserve retained cell values, row order, headers and column order. Arbitrary headers need no mapping. Unicode, quoted commas, multiline fields, blank cells and leading zeros are supported.
One UTF-8 comma CSV with a header, up to 8 columns. Basic: 500 rows / 150,000 bytes. Standard: 2,000 / 600,000 bytes. Premium: 5,000 / 1,500,000 bytes. Both limits apply; rows exclude the header.
Receive a separate cleaned CSV plus counts, duplicate references and input/output hashes. Original unchanged. One bounded revision within the same file/scope.
Exact full-row dedupe only: no fuzzy matching, similar-duplicate detection, guessed repairs, general cleaning or type conversion. Malformed CSV/inconsistent widths are refused, not repaired. CSV quoting may change; retained parsed values do not. Formula-like text remains: import as text. No sensitive or personal data.
FAQ
Can you clean any CSV?
One UTF-8 comma CSV with a header and up to 8 columns. Arbitrary headers need no mapping. Basic: 500 rows/150,000 bytes; Standard: 2,000/600,000; Premium: 5,000/1,500,000. Both limits apply. This is exact full-row dedupe, not general cleaning.
What will change?
Only exact duplicate full source rows are removed. Retained cells, original headers and accepted extra fields are preserved. Issues and provenance are reported, not guessed repairs.
Can I send personal data?
Only synthetic or genuinely anonymized data is accepted. No real personal registers, sensitive data or credentials. Do not send raw personal data in examples or messages.
Is the result Excel-safe?
Not guaranteed. Formula-like raw values may remain and be flagged, including in reports. Use a text editor or controlled text-only import without formula evaluation; do not open blindly in Excel.
What if my file is unsupported?
It may be refused, including before ordering. Requirements cannot prevent Fiverr orders automatically. A QA-approved refusal is not cleaned delivery; existing orders follow platform rules and applicable rights.
What does the correction include?
One bounded revision corrects an error in agreed exact-row work on the same original file. A new file, expanded limits, fuzzy matching or transformations are outside scope. Platform rules and applicable customer rights remain in force.
