I have several Excel-based spreadsheets that hold all of my customer records, and I need this information migrated into a clean, structured database/CRM environment. The job involves extracting every row from the existing XLS/XLSX files, standardising field names, removing duplicates, resolving obvious data-quality issues, and loading the final dataset into the destination I will specify once the mapping is confirmed. You will receive: • The original Excel files (multiple workbooks, mixed layouts). • A field-mapping template that shows where each column must end up. I expect: • A script or repeatable process (Python, Power Query, ETL tool of your choice) that performs the transformation. • A validated target data file or direct import into the agreed database/CRM, with no lost or corrupted records. • A brief hand-over note describing the steps so I can reproduce the migration in the future. Accuracy and data integrity are critical—every customer must move across exactly once, with emails, phone numbers, and purchase history intact. If you’re comfortable wrangling Excel data and automating clean migrations, let’s get started. Note: Need to WORK FROM OFFICE ONLY. LOCATION: NERUL WEST NAVI MUMBAI 400706.
