Messy lists made consistent: names, phones, dates, duplicates, prices typed five ways.
A one-page summary with totals, trends and a chart that updates when you paste in new data.
Which services make money? Why was July slow? Who are your best customers? A written answer from your own data.
Prices are starting points. I send a fixed quote in writing before any work begins, so there are no surprises.
Built from the cleaned sample data above (fictional lawn-care business, April to September 2026).
Billed by month (jobs with a clear date)
The cleanup sample fixed 65 messy rows down to 60 (5 duplicates removed) and flagged 8 rows that need a human answer instead of a guess. The full Excel files are available on request.
Your files are used only for your job and deleted when it's done if you ask. I'm happy to sign a short confidentiality note.
I'm a Boise-based data scientist with a master's degree in data science. I take the spreadsheet work that eats your evenings and do it carefully. Data Thirteen is a small, one-person business, so you always deal with the person doing the work.
Email a description of the problem and, if you can, a copy of the file with any private details removed. I reply with a price and a date.
