FAQ
What file formats do you work with?
I primarily work with Excel (.xlsx, .csv, .xlsb) and Google Sheets. I can also process data from PDFs, TXT files, or exported SQL tables to get them ready for your analysis.
Can you clean data for Power BI or Tableau?
Yes! As a data analyst, I understand how these tools require "long" vs. "wide" data formats. I will structure your tables, fix data types, and ensure your headers are clean so you can import them directly into Power BI, Tableau, or MySQL without errors.
What if my data is in a PDF or scanned image?
I can definitely help with that! I use specialized tools to extract data from PDFs and then clean it. Please message me first with a sample of the PDF so I can confirm the complexity and give you a custom quote.
Can you explain the changes you made?
Absolutely. With every delivery, I include a brief "Data Summary" note explaining the steps I took (e.g., "Removed 45 duplicates," "Standardized 3 date formats"). This ensures you know exactly how your data was improved.
Is my data kept confidential?
100%. Your data privacy is my top priority. I never share client data with third parties and am happy to delete all files from my system once the order is completed and you are satisfied.
Will I receive the fully editable source file?
Yes! Once the project is complete, I will deliver the cleaned and organized data in your preferred format (Excel .xlsx, CSV, or Google Sheets). You will have full ownership and control over the final dataset.
