CSV and Excel data cleanup with automated reportsIlya Asminkin
Turn inconsistent exports into a reliable dataset and a report people can use. I clean CSV and spreadsheet data, build repeatable transformations and create practical summaries for recurring business reporting.
Start with the question the report should answer
We identify the fields that matter, the inconsistencies in the source and how the output will be used. The wider service can include joining exports, recurring report generation and preparing structured data for another application.
A clean dataset and report for $100
The starter handles up to two files, 10,000 rows in total and 20 columns. It includes agreed formatting and type normalization, exact-duplicate handling, a missing-value report and up to three summary tables or charts. We agree the matching and exclusion rules before changing records.
Make the result checkable
I first inspect a representative sample and propose the cleanup rules. The delivery includes before-and-after row counts, a record of excluded or ambiguous entries and checks for the agreed totals. One consolidated revision round lets us refine the output within those rules.
A repeatable process and usable files
You receive cleaned CSV or XLSX files, the summary report and a reusable script or documented transformation steps. Original source files are preserved. Recurring scheduled delivery or live dashboard integration can be added as a separate milestone.
