Data Cleanup And Book Formatting

I turn messy files into clean, usable ones. Two things I do fast: clean and structure chaotic spreadsheets — broken headers, mixed date formats, duplicates, merged cells — and format manuscripts into ...

About this Gig

Send me the file. Get it back clean.

Duplicates, inconsistent date formats, names in five different capitalizations, merged cells, headers buried in row 8, numbers stored as text, broken encodings from old exports I fix all of it.

What you get

Your file cleaned, structured and ready to use
A short summary of exactly what I changed
Both .xlsx and .csv versions
Existing formulas preserved and working

I work with Excel, Google Sheets, CSV, TSV, and exports from CRMs, accounting software and databases.

I process files with Python, not by hand so large or ugly files are not a problem. Need more than 10,000 rows? Message me and I'll set up a custom offer.

Not sure if your file is fixable? Send it over before ordering and I'll tell you exactly what can be done with it.
