Get one limited, non-sensitive Excel or CSV file cleaned and documented without silent changes to business logic.

The fixed pilot includes:

one existing Excel or CSV file;

up to 1,000 data rows in total;

up to two simple worksheets and fifteen columns;

cleanup of confirmed duplicates, inconsistent data types and obvious formatting issues;

preservation of the original file;

one cleaned copy and a short change log;

one revision round for agreed scope corrections.

Formulas, macros, calculations, external links and ambiguous business values are left unchanged. If those are central to the problem, the file is outside this pilot.

Do not send the real file before scope and privacy have been checked. Files with payment data, health data, identity documents or other sensitive personal information are not accepted for this pilot.

Fixed pilot price on Contra: $69.
