I will clean up your messy CSV files and remove duplicate rows

Send me a messy CSV and get back a clean one, plus a plain-text report listing every change that was made.

What I do:

• Trim stray spaces around values and column names
• - Remove empty rows and exact duplicate rows
• - Split one file into parts, by a column's values or a fixed row count
• - Merge several files with matching columns into one, tagged by source
• - Report on a file without changing it, if you just want to know what is wrong

What I do NOT do, so there are no surprises:

• Guess missing values or invent data
• - Merge records that merely look similar
• - Convert ambiguous dates, because 03/04 could be March or April
• - Check whether your data is factually correct

Formula-like cells are flagged, never silently rewritten.

File limits: UTF-8 comma-separated CSV, up to 2 MB and 20 columns per file.

You keep your original. Every job returns a report with row-level detail and a checksum, so you can verify exactly what changed before you rely on it.

Not sure which package fits? Message me your row and column count and I will tell you.
