Overview

Every business runs on spreadsheets nobody has properly audited in years, and this cleans, merges and restructures them into something that can actually be reported from — using AI (ChatGPT, Claude, Python) to accelerate the pattern work while a repeatable script, not just the one cleaned file, is the real deliverable. Without that script, the same mess reliably returns within a quarter, which is why this is priced per project with the script itself as part of what's delivered.

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

  1. Take a copy first and never work in the client's original file.
  2. Profile the data before changing it: row counts, blanks, duplicates, mixed types in one column.
  3. Ask the owner what each ambiguous column means rather than guessing.
  4. Write the transformation as Python so it is repeatable and reviewable.
  5. Use ChatGPT to draft the cleaning logic, then test it against rows you have checked by hand.
  6. Keep every original value alongside the cleaned one so any change can be traced.
  7. Handle dates and currency explicitly; silent locale coercion is the classic destroyer.
  8. Report what you changed and what you could not resolve.
  9. Hand back both the clean file and the script that produced it.
  10. Price per file by size and messiness, quoted after profiling.
  11. Offer to rebuild the intake so it stops getting dirty at source.
