Over deze dienst

Messy spreadsheet? I will turn it into clean, consistent data that is ready for analysis, reporting or import.


What I do:

Remove duplicates and empty rows

Fix dates, numbers, names and text formats

Handle missing values and obvious errors

Split, merge and standardize columns

Add data validation to keep it clean

Use Power Query for files you refresh regularly


What I need from you:

- Your Excel, Google Sheets or CSV file

- A short note on what "clean" means for you (formats, rules, columns that matter)


What you get:

  • The cleaned file in the format you sent
  • A short summary of all changes made
  • Your original file untouched, so nothing is lost


About me: I work in controlling and data analysis (Excel, SQL, Power BI), so I care about accuracy and consistency, not just a nice look. Your data stays confidential.


Before ordering, please message me with a sample of your data and the approximate number of rows, so I can recommend the right package.
