FAQ
What file formats do you accept for the raw data?
I can work with almost any standard data format. The most common formats I receive are Excel (.xlsx), CSV, Google Sheets, text files, or raw SQL database exports. If you have a different format, just send me a message!
How do you define an "item" in your packages?
An "item" refers to a single row or record in your dataset. For example, if you have a spreadsheet of customer contacts, one customer (including their name, email, phone number, etc., across multiple columns) counts as one item.
What if my dataset has more than 1,000 items?
No problem at all! The Pro Max plan covers up to 1,000 items, but I regularly handle much larger datasets using automated Python scripts and advanced SQL queries. Send me a message with your file size, and I will create a custom offer for you.
Can you also analyze the data or build a dashboard after cleaning it
Absolutely. Clean data is just the first step. As a comprehensive Data Analyst, I also offer custom Power BI dashboards and advanced SQL reporting. Let me know what insights you want to see, and we can combine data cleaning and visualization into one complete project.
What exactly does "data cleaning" include?
Depending on the package you choose, it includes removing duplicates, fixing formatting errors (like standardizing dates or text cases), handling missing values, splitting or merging columns, and validating the data structure so it is completely ready to be imported into your CRM or analytics tools.
