Sobre este Serviço
Messy spreadsheet slowing you down? I clean Excel and CSV data so every row is accurate, consistent, and ready to actually use.
I've cleaned datasets up to 50,000 rows across 18 columns, fully reconciled so nothing goes missing. Every order runs through a 10-point verification before it reaches you.
What I clean:
- Duplicate and conflicting rows
- Dates in mixed formats, fixed to one standard
- Inconsistent names, categories, and text
- Numbers stored as text, mixed currencies
- Missing and impossible values (flagged, never guessed)
- Broken totals recalculated
What you get:
- Clean file in Excel or CSV
- Change log showing every fix with before/after examples (Standard & Premium)
- Validation report proving the file passed all quality checks (Standard & Premium)
Nothing gets changed or deleted without appearing in your change log, so you always see exactly what happened to your data.
Pick the package that fits your row count and place your order. Have an unusual file? Send me a message first and I'll confirm the scope.

Perguntas frequentes
What does "flagged, never guessed" mean?
If a value is missing or looks wrong (like a negative quantity), I mark it in a separate column instead of inventing a number. The original value stays untouched so you can see exactly what's questionable and decide yourself.
I'm not technical. Will I get a normal Excel file I can open?
Yes. You send a normal Excel or CSV file and get one back the same way, just clean. No code or special software needed on your end.
Will you delete or change anything without telling me?
No. Duplicates are removed and counted, everything else is flagged not deleted. Standard and Premium orders include a change log listing every single change with before/after examples.
What happens to blank cells or wrong values like a negative quantity?
I flag them in a separate column instead of inventing a value. The original stays visible so you can see what's questionable and decide, rather than me guessing.
Is my data kept private?
Yes. Your file is used only to complete your order and is never shared or reused. If it contains sensitive info, I can mask those columns first, just ask.
How fast will I get it back?
Basic in 1 day, Standard in 2, Premium in 3. Need it sooner? Rush delivery is available as a paid extra
What is the difference between the 3 packages?
Basic (100 rows): duplicates and formatting only, fast turnaround. Standard (1,000 rows): full cleaning plus change log and validation report. Premium (10,000 rows): everything in Standard plus a reusable script.
