FAQ
What is the primary business goal of this Merging project?
Please define the most crucial business decision the merged data will support (e.g., "We need to calculate accurate profit-per-customer" or "Forecasting inventory needs"). This ensures I align my solution directly with your high-value objective.
My source data might have inconsistencies (e.g., short forms, errors, misspellings). What should I tell you upfront?
For an Advanced Solution, we need a clear Cleaning Protocol. Please list: (a) The top 3 known errors (e.g., missing IDs). (b) Any necessary synonyms (e.g., 'Cust' = 'Customer'). (c) Which specific columns must NOT be altered.
Can you fix my data if the original entry was factually wrong (e.g., a wrong price or score was entered in the source file)? (Data Integrity)
IMPORTANT: I require confirmation that the source data is factually genuine and correct. Excel CANNOT detect factual entry errors ("Garbage In, Garbage Out"). I cannot be responsible for errors residing in the original source data.
My Row Count does not exactly match your packages (e.g., 35,000 Rows). How will you calculate the price?
My pricing is transparent. Message me with your Row Count and source file count. I will calculate a Deserved Custom Offer that accurately reflects the complexity and effort for your high-value project.
Will you share my confidential data?
Absolutely not. Data confidentiality is my highest priority. I treat your information with the utmost professional care, following strict security protocols. Your data will be deleted from my system 7 days after project completion.
Can you handle datasets larger than 200,000 rows?
Yes. While my standard packages mention 200K rows, I can handle much larger datasets using Power Query and Data Modeling. Please message me for a custom quote if you have millions of rows.
Do I need to provide a sample file before ordering?
Highly recommended. Every data structure is unique. Reviewing a sample helps me ensure 100% accuracy and determine if your project fits the Basic, Standard, or Premium tier.
Will the dashboard update automatically when I add new data?
Absolutely. I build "1-Click Refresh" systems. As long as the new data follows the same structure, you just need to click 'Refresh' to see the updated insights instantly.
Do you provide strategic business recommendations along with charts?
Yes. In the Premium package, I analyze the "Why" behind the numbers—identifying risks like high attrition or ROI leakage—and provide actionable strategic points to help your business grow.
