Excel Data Cleanup & Database Formatting

$35/hr Starting at $49

Need to turn a messy spreadsheet into structured, import-ready data? I clean, split, merge, validate, deduplicate, and reorganize Excel, CSV, and Google Sheets data for reliable use in databases, reports, CRM imports, and business operations.


I can:

• Split combined addresses, names, and text into consistent columns using formulas, Power Query, SQL, or Python

• Standardize dates, phone numbers, categories, identifiers, and missing values

• Remove duplicates and flag conflicts instead of silently deleting information

• Merge or reconcile multiple workbooks and CSV exports

• Build validation checks, exception reports, and repeatable cleanup workflows

• Prepare clean files for database, CRM, accounting, and reporting imports


You receive the original preserved as a backup, the cleaned output, a concise data dictionary or change log, validation results, and a reusable script or query when automation is appropriate. For well-scoped files, I can usually provide a working sample or first version within 48 hours. Send a sample plus the desired output columns and I will confirm the fastest reliable approach.Broken formulas, messy imports, duplicates, slow workbooks, and unreliable reports cost time. I repair and automate Excel and Google Sheets files, with a working first version typically delivered within 48 hours.


What I can handle:

• Fix formula errors, broken references, lookups, pivots, charts, and formatting

• Clean, merge, deduplicate, and validate spreadsheet data

• Build clear KPI reports and dashboards in Excel or Power BI

• Automate repetitive work with Excel, Google Sheets, Python, SQL, or R

• Add checks and concise handoff notes so the result stays maintainable


You receive a backed-up source, a cleaned final workbook, validation checks, and a short explanation of every important change. I work from the business outcome backward: accurate numbers, fewer manual steps, and a file your team can confidently reuse.


Send the workbook plus a short description of what is wrong. I will review it, confirm the scope, and recommend the fastest practical fix before work begins. Small repairs are welcome; larger dashboard and automation projects can be scoped in milestones.
