Leading with a strong knack for problem-solving, I've got extensive experience cleaning large datasets and ensuring they're in the best condition possible for further analysis - exactly what you need. With my proficiency in Excel functions such as VLOOKUP/XLOOKUP, TEXTSPLIT, and Power Query, I can tackle the task of de-duplicating rows while retaining the most complete records with ease. Not only that, but I am equally skilled at standardizing diverse data formats, like dates, phone numbers, and addresses to ensure uniformity across your entire dataset. Apart from my technical proficiency, I also have a keen eye for detail which is central to cleaning data. I will not just import and clean your raw files but will also validate every row to flag any obviously invalid or missing data for your review. This way, I can ensure all mandatory columns are either filled or marked "MISSING". Additionally, I'll provide you with an encompassing change log outlining all key cleaning actions performed on your dataset. Let my track record of consistent quality stand as evidence of my ability to handle this project adeptly. As a top-ranked freelancer (currently sitting at #6168) in a pool of hundreds of thousands globally and recognized under the top 1%, you can rest assured that selecting me for this project means giving it into capable hands. Let's get started today and see your dataset transformed!

Data cleaning with Python is my core service. My recent work: multiple raw CSVs merged into a single clean output — duplicates removed, formats standardised, missing values flagged, change log delivered. For your files I'll handle deduplication (keeping the most complete record), E.164 phone formatting, DD/MM/YYYY dates, address standardisation, and MISSING flags on every incomplete mandatory field. Clean .xlsx + change log on delivery. Send me the files and I'll start same day. — Sai

@Dtrujillo2026

Hi! Data cleaning and structuring is something I've done professionally, and this project is a great fit for my background. I'll import all your source workbooks, de-duplicate records keeping the most complete version of each, and standardize everything — column headers, date formats to DD/MM/YYYY, phone numbers to E.164, and address casing — consistently across every row. Any missing or clearly invalid data will be flagged so nothing slips through quietly. You'll end up with one clean, analysis-ready Excel file that opens without errors in Excel 365, plus a clear change log detailing every cleaning action taken. I'm comfortable with VLOOKUP/XLOOKUP, Power Query, and TEXTSPLIT, and my professional background in SQL and large-scale data migration means I think about data integrity at every step — not just surface formatting. I've handled messy, inconsistent datasets before and I know how to make decisions about edge cases without needing to come back with questions on every row. The deliverable will be CRM-import ready from the moment you open it. Share the files whenever you're ready and I'll give you a turnaround estimate based on volume. Happy to do a quick sample clean on the first sheet so you can verify the output format before I work through everything. Looking forward to it!

Hello, how are you? I'd be happy to offer my professional services with immediate availability. It's a task I handle perfectly well. I have over 25 years of experience in quantitative data management, from data entry to cleaning, consistency, processing, and database analysis. I've worked for several years in private consulting firms and universities conducting quantitative public opinion studies, as well as in third-sector organizations monitoring and systematizing social aid projects, and in government agencies monitoring social programs. In all cases, I've focused on loading, cleaning, processing, and analyzing data from various sources (including JPG images). I've worked with databases in very poor condition, which has honed my skills. I have a perfect command of Excel, especially its tools for loading, cleaning, and analyzing data (validation rules, conditional formatting, pivot tables, formulas, and macros). I also specialize in using SPSS, Access, Power BI, and other data management software. I am very meticulous and detail-oriented in my work because I like to do several checks before delivery to guarantee the quality of the work. I can start today. To estimate the total work time, I would need to know the number of records, the number of fields (columns), and, if possible, the data type (numeric, dates, text, etc.) and its complexity. Best regards, Marco
