Messy spreadsheet? I will turn your Excel or CSV file into an organized, usable dataset.


Depending on your package, I can remove agreed duplicates, trim extra spaces, standardize dates and numbers, split or combine columns, and merge files with compatible layouts.


You receive the cleaned XLSX or CSV, a brief change summary, and a separate list of ambiguous records that need your decision. I keep the original source unchanged and do not guess missing values.


Basic covers 1 file, up to 100 rows and 10 columns, with up to 3 agreed cleanup rules. Larger packages add files, rows and rules. Revisions cover the original agreed requirements.


Please message me with a small anonymized sample and your desired result before ordering. Scanned PDFs, handwriting, macros and complex fuzzy matching require a separate quote.


I use AI-assisted tools where appropriate and validate the output. Portfolio examples use fictional data.
