FAQ
Can you sign a Non-Disclosure Agreement (NDA) for confidentiality?
Absolutely. I understand that business information is highly sensitive. I am completely willing to sign a standard Non-Disclosure Agreement before you share any spreadsheets, databases, or project details with me. Your data will remain 100% secure, private, and confidential.
What files do I need to provide for an Excel assignment or project?
You should provide your raw files in CSV, XLSX, or TXT formats along with a clear note explaining your goals. If you have an Excel assignment from school or a corporate guidelines document, please attach that too so I can perfectly match the required structure and instructions.
Can you handle large, messy datasets that require extensive data cleaning?
Yes, I specialize in fixing messy datasets. I will perform deep data cleaning by removing duplicates, fixing broken text, merging scattered columns, and deleting blank spaces. I format everything into clean, tabular structures that make future analytics fast and completely error-free.
Do you use Power Query to automate repetitive spreadsheet tasks?
Yes, I use Power Query extensively to build automated ETL data pipelines. This means once I build your custom solution, you can simply drop new monthly or weekly raw files into your folder and hit refresh. The system will automatically clean and update your reports instantly.
What is the difference between an Excel dashboard and Power BI?
Excel dashboards are fantastic for quick, spreadsheet-based tracking using native toolsets. Power BI is an advanced business intelligence tool designed for massive datasets, cloud sharing, automatic scheduled updates, interactive visual sorting, and highly advanced DAX reporting models.
Can you fix complex, broken Excel formulas in my existing sheets?
Yes, I can repair any broken logic or calculation errors. I am highly proficient in writing and fixing complex Excel formula structures, including advanced XLOOKUP, nested IF statements, INDEX-MATCH arrays, and dynamic text formulas to ensure your workbooks run flawlessly.
What kind of metrics can you build using custom DAX expressions?
I write customized DAX measures to calculate complex business KPIs. This includes advanced time-intelligence calculations like Year-over-Year growth, running totals, custom date filters, and deep ratio splits that standard Pivot tables cannot calculate on their own natively.
How do your Pivot table layouts help with corporate data analysis?
I design structured Pivot table configurations that summarize millions of rows of data into easy-to-read executive summaries. You will be able to filter your business data by date, region, product, or employee instantly, allowing you to run your own deep data analysis smoothly.
What styles of data visualization do you include in your reports?
I build executive-ready data visualization layouts using the best chart styles for your specific data story. This includes dynamic bar charts, trend lines, scatter plots, geographic maps, and KPI cards, all styled with clean color palettes to make your metrics pop instantly.
Do you offer custom pricing if my project falls outside your packages?
Yes, I offer flexible custom pricing for unique projects. If your project has a highly specific scope, huge data volume, or short deadline, just send me a message. I will analyze your files and send you a custom tailored offer that fits your exact technical budget perfectly.
