I will clean and validate CSV data with a clear quality report
About this Gig
Messy CSV files cause unreliable reports, failed imports, and hours of manual checking. I will clean and validate your data with a reproducible Python workflow and show exactly what changed.
Every package includes a separate cleaned file and a concise quality report covering input and output row counts, exact duplicates, blank cells, and the agreed cleanup rules. I never overwrite your original file or silently guess ambiguous values.
Typical fixes include: trimming inconsistent whitespace, removing exact duplicate rows, normalizing agreed date or category formats, flagging incomplete records for review, and reconciling row counts before delivery. Standard and Premium add custom validation rules, a reusable Python script, and clear audit outputs. Message me before ordering if your file has unusual encoding, sensitive fields, fuzzy matching needs, or exceeds the listed limits. Do not send passwords, payment credentials, government identifiers, or private medical data.
FAQ
Will you overwrite my original file?
No. I return a separate cleaned file and leave your source file unchanged.
Do you guess missing or ambiguous values?
No. Unless we agree on an explicit rule, ambiguous values remain unchanged and are flagged for review.
Are Excel files included?
This Gig is scoped to CSV. Please message me before ordering for XLSX files, formulas, multiple sheets, or formatting.
