Steps for completing your project
After purchasing the project, send requirements so Madison can start the project.
Delivery time starts when Madison receives requirements from you.
Madison works on your project following the steps below.
Revisions may occur after the delivery date.
Step 1: Project Kickoff & Dataset Review
You provide the dataset(s) (Excel, Google Sheets, or CSV) along with any specific formatting rules or business requirements. I review the files to confirm scope, structure, and key issues (duplicates, missing values, inconsistencies, etc.).
Step 2: Data Cleaning & Error Correction
Remove duplicates and fix inconsistencies across datasets. Handle missing values (either imputing or flagging them, depending on your preference). Correct formatting issues (dates, currencies, categories, text).
