Why it works
Businesses run on spreadsheets nobody has audited in years, and the repeatable script matters more than the cleaned file - without it the same mess returns within a quarter.
How it makes money
Per deliverable + retainer
How to start
- Take a copy first and never work in the client's original file.
- Profile the data before changing it: row counts, blanks, duplicates, mixed types in one column.
- Ask the owner what each ambiguous column means rather than guessing.
- Write the transformation as Python so it is repeatable and reviewable.
- Use ChatGPT to draft the cleaning logic, then test it against rows you have checked by hand.
- Keep every original value alongside the cleaned one so any change can be traced.
- Handle dates and currency explicitly; silent locale coercion is the classic destroyer.
- Report what you changed and what you could not resolve.
- Hand back both the clean file and the script that produced it.
- Price per file by size and messiness, quoted after profiling.
- Offer to rebuild the intake so it stops getting dirty at source.
