Acerca de este Servicio
I will clean and deduplicate your Excel or CSV spreadsheet so it is easier to read, filter, review, and use.
Work can include:
- Removing or marking duplicates using your agreed matching columns
- Standardizing columns
- Cleaning inconsistent formatting
- Formatting names, cities, statuses, dates, or categories
- Flagging missing or unclear values
You receive:
- A cleaned copy in your agreed Excel or CSV format
- A short change summary explaining what was cleaned
- Clear flags for uncertain matches or missing values
Your original file is preserved. I flag uncertainty instead of guessing and leave uncertain duplicates for your review rather than deleting them without approval.
Best for:
- Prospect lists
- CRM exports
- Event lists
- Supplier lists
- Admin tracking sheets
- Small business spreadsheets
Please message first if your file contains sensitive personal data, complex formulas, or very large datasets.

FAQ
What do you need from me to start?
Please upload the spreadsheet or CSV and tell me what the file is used for, which columns matter most, whether duplicates should be removed or marked, how missing values should be handled, and your preferred final format.
What spreadsheet file types do you accept?
I can work with Excel XLSX, CSV and Google Sheets exports. Contact me before ordering if the workbook contains macros, complex formulas, protected sheets or sensitive personal data.
Will you remove duplicates automatically?
I can remove duplicates or mark them for review. Tell me which columns define a duplicate. If a match is uncertain, I flag it rather than deleting data without approval.
Will you preserve formulas and workbook structure?
Yes, when you identify the formula columns and structure that must remain. Please contact me before ordering for macros, pivots, linked workbooks or complex formulas.
What happens when information is missing or unclear?
I flag missing or unclear values instead of guessing. Researching new information is not included unless we agree on a separate research scope before the order.
