What I will do, step by step:

• Inspect your spreadsheet and note data quality issues.
• Clean and normalize values (dates, numbers, text casing, phone/email formats).
• Remove exact and near-duplicate records using reliable matching rules.
• Merge datasets or worksheets while maintaining data integrity and resolving key conflicts.
• Split combined columns into separate fields (for example, full name → first name / last name).
• Sort and filter data according to your criteria.
• Standardize formatting (headers, column types, date formats, number formats).
• Validate results and fix any broken formulas or references.
• Convert the final output to the format you need (XLSX, CSV, or Google Sheets).

What you will receive:

• A clean, well-structured Excel file ready for analysis or import.
• A brief changelog that lists the main fixes performed and any assumptions made.
• If used, the scripts or formulas I created (simple macros or formula notes) so you can reproduce steps.
• Up to two free revisions to ensure the final file meets your needs.

How this helps you:

• Saves time by eliminating manual cleaning tasks.
• Reduces errors in reports and analyses.
• Makes data import into other systems reliable.
• Improves the accuracy of business decisions based on your data.
