You will get a clean, standardized, and system-ready Excel or CSV data file
Project details
Messy raw data exports and chaotic master files can break your CRM software, cause email bounce-backs, and waste hours of manual effort. I specialize in transforming unstructured, duplicate-heavy, and poorly formatted spreadsheets into clean, system-ready files.
My Core Solutions include:
• Removing hidden spaces, bad casing, and broken text strings (TRIM, PROPER, CLEAN).
• Standardizing international phone numbers, email addresses, and date formats.
• Deduplicating contact lists based on custom unique keys.
• Splitting or merging columns (e.g., Full Names -> First/Last Name, Addresses).
• Custom formulas and dynamic sheet structure for recurring cleaning tasks.
You will receive a final, fully updated, and error-free deliverable ready for immediate system import or accurate data analysis.

About Rezwan
Excel Specialist | Data Infrastructure & Excel Automation
Khulna, Bangladesh - 12:52 pm local time
I help businesses turn chaotic raw Excel exports into clean, automated, and structured data systems. I don't do visual design or storytelling—I build the logical, error-proof back-end infrastructure that makes your data reliable.
🔧 What I can help you with:
• Data Cleaning & List Hygiene: Scrubbing, formatting (TRIM, PROPER), and de-duplicating massive datasets to prepare them for flawless CRM or E-commerce migrations.
• Advanced Formula Logic: Implementation of multi-criteria filters and data strings (SUMIFS, COUNTIFS, nested IFS, IFERROR, and subtotal with criteria).
• Automated File Splitting: Deploying searched-and-optimized VBA scripts to automatically slice a single master spreadsheet into individual sheets or standalone files based on your criteria in one click.
• Executive Summary Top-Sheets: Compressing thousands of rows of tracking data into clean, logical summary boxes and pivot layouts that reflect core business logic.
• Fixing Broken Workbooks: Debugging slow spreadsheets, correcting formula errors, and removing repetitive manual steps.
📊 Core Excel Architecture:
▪ Multi-criteria sum and count operations (SUMIFS, COUNTIFS, SUMPRODUCT)
▪ Advanced lookup and reference integrations
▪ Data transformation pipelines and structural formula design
▪ Basic VBA automation for file handling and task optimization
I focus entirely on structural logic, speed, and accuracy. If you have a messy dataset or a broken formula slowing down your operations, send me a message. I am happy to review a sample of your file and map out the exact fix.
