Über diesen Service
Messy data leads to wrong decisions. I turn your raw, inconsistent spreadsheets into clean, accurate, analysis-ready data.
Whether your data comes from Excel, CSV files, exports or multiple sources, I will fix the problems that slow you down.
What I can fix:
Duplicate rows and records
Missing, blank or incorrect values
Inconsistent dates, text, currency and number formats
Spelling variations and mismatched categories
Outliers and data entry errors
Merging and reshaping data from multiple files
How I work:
1. You share your file and tell me what "clean" means for you
2. I clean it using Excel, Power Query or Python (Pandas)
3. You get the cleaned file plus a summary of the changes
Why work with me:
Your original file is never overwritten
Clear communication and on-time delivery
Your data stays confidential
Message me with a sample of your data before ordering and I will confirm the best package for you.

FAQ
What file formats do you accept?
Excel (.xlsx, .xls), CSV and Google Sheets (shared as Excel or CSV). If your data is in another format, message me before ordering.
Will you overwrite my original file?
No. Your original file stays untouched. I deliver a separate cleaned file so you can always compare the two.
Will I know what you changed?
Yes. Standard and Premium include a cleaning summary report. On Basic, message me and I will share a short note of the main changes.
Is my data kept confidential?
Yes. I only use your data for your order and never share it. I can delete it after delivery if you ask.
Can you set this up so I can repeat the cleaning myself?
Yes. The Premium package includes a reusable Python script or Power Query steps, so you can clean similar data in the future.
Can you also build a dashboard from the cleaned data?
Yes. Check my Data Visualization gig, or message me and I will prepare a combined offer.
