I will do data cleaning for an organized CSV
Data cleanup, automation and API integration
À propos de ce service
Turn a messy CSV into a consistent file you can use. I will trim unwanted spacing, normalize email, phone and date columns using your named lists or automatic header detection, and remove exact duplicate rows according to your choices.
Every package includes your cleaned CSV, untouched original, a change report and a reusable Python cleaning script. Independent checks reconcile row counts and reproduce the result. Invalid dates and phone values are preserved rather than guessed.
Choose the package for your row count; each covers one UTF-8 CSV up to 2 MB. Export Excel or Google Sheets as CSV first. Workbook formulas, colors, multiple-file joins, fuzzy matching and new data research are outside this gig.
Work is AI-assisted. No calls or account access are needed. Send the file and the structured cleaning choices on Fiverr; import the returned file as text to preserve its values.
FAQ
What exactly will I receive?
The cleaned CSV, original file and checksum, change report, reusable Python script, setup notes and AI-use disclosure.
Will you guess missing or incorrect values?
No. Blank values stay blank. Unsupported dates and phone values remain unchanged. This gig does not research or invent missing facts.
Can you clean an Excel workbook?
Export the relevant sheet as CSV. This gig returns CSV and does not preserve workbook formatting, formulas or multiple tabs.
How are duplicates identified?
Only rows that are identical after the selected cleaning steps are removed. Similar names, addresses or partial matches are not automatically merged.
What CSV structure is supported?
One UTF-8 CSV with at most 1,000 columns, nonempty unique headers and equal-width rows. When trimming is selected, headers must stay nonempty and unique after trimming; use those trimmed names in your column lists.
