For this project I need customer information that is currently scattered across several files merged, de-duplicated, and polished inside one master Excel or Google Sheets workbook. Once the sheet is tidy, every contact detail—name, phone, email, and address—has to be cross-checked against reliable web sources to make sure the data is accurate and up to date. When the verification step is done, the final workbook must follow my formatting guidelines (column order, header style, conditional colour coding). I will share a short style guide and a small sample so you can mirror the look and feel exactly. Deliverables • Cleaned and consolidated customer-info spreadsheet • Column-by-column log of any corrections made, including URLs or screenshots that confirm each updated contact detail • Final file delivered in Excel and Google Sheets formats, formatted to the provided guidelines A sharp eye, solid command of Excel formulas and data-validation tools, plus clear, timely communication are must-haves. If that sounds like you, let’s get started right away.

Hi there, I'm a Data & Automation Specialist working with Python and Excel to clean, consolidate, and verify business data at scale. I specialize in merging messy multi-file datasets, de-duplication, and web-based data verification — with a 5.0★ rating and 100% on-time, on-budget delivery. Here's how I'll approach your project: My understanding: You have customer records scattered across several files that need to be merged into one clean, de-duplicated master workbook — then every contact detail (name, phone, email, address) cross-checked against reliable web sources, logged column-by-column with proof, and formatted to match your style guide exactly, delivered in both Excel and Google Sheets. My plan: Consolidate & standardize — merge all source files into one structure, normalize each field (phone formats, email casing, address components) so records become comparable. De-duplicate intelligently — catch not just exact duplicates but near-matches (typos, spacing, formatting differences) using fuzzy matching, and flag any ambiguous merges for your quick confirmation rather than guessing. Verify against the web — cross-check each contact detail against reliable public sources, tagging every record with a confidence status (Confirmed / Corrected / Needs review) and logging the supporting URL or screenshot for each correction. Format & QA — apply your exact column order, header style, and conditional colour coding from your guide, run a final validation pass, and deliver in both Excel and Google Sheets. Deliverables: Cleaned & consolidated master workbook + column-by-column correction log (with confirming URLs/screenshots) + both Excel and Google Sheets versions, formatted to your guidelines. Timeline: 3–4 days (scales with record count) · Tools: Excel formulas & data-validation, Python/Pandas, Google Sheets Two quick questions so I match your expectations exactly: Roughly how many records and source files are we working with? For verification, are there specific sources you trust most (e.g. company websites, official directories), or should I use my best judgment on source reliability? I'll clean and verify a small sample for free first, matched to your style guide, so you can check my accuracy and formatting before awarding — and I'll keep you updated with short progress notes so nothing drifts from what you want. Ready to start right away — let's discuss the details.

Hi there, Consolidating scattered customer data into one clean, verified master sheet is exactly the kind of work I do well, and I would like to help you get this done right. Here is what I will deliver: a fully merged, de-duplicated spreadsheet with every contact record checked for accuracy across reliable web sources. For each correction I make to a name, phone number, email, or address, you will receive a column-by-column log with the source URLs or screenshots that back up the change. The final file will be formatted strictly to your style guide, covering column order, header style, and conditional colour coding, and delivered in both Excel and Google Sheets formats. Since I am newer on the platform, I want to make this easy for you: I am happy to work on a milestone basis so payment is only released once you are satisfied with the result. I will also provide free revisions until the workbook looks and functions exactly as you need it. I am based in Zadar, Croatia, available across time zones, and ready to start as soon as you share the sample files and style guide. Looking forward to hearing from you.

Hi, I can consolidate your customer files into a clean, de-duplicated and consistently formatted master workbook, while maintaining a clear audit trail of corrections. My approach would combine structured data cleaning with careful verification of contact information against reliable public sources. Each correction can be logged with the original value, corrected value and supporting source, making the final dataset easy to review and audit. I can also reproduce your formatting guidelines, including column structure, headers, validation rules and conditional formatting, and provide the final workbook in the requested formats. I use Python for data processing where automation improves accuracy and consistency, alongside spreadsheet tools for the final presentation and validation. Before starting, I would like to confirm the approximate number of customer records and files, as the web-verification workload depends significantly on the dataset size. Based on the scope described, I can target an initial delivery within 5 days. Best regards, Romain

You need scattered customer files merged into one master sheet, de-duplicated, then each name/phone/email/address checked against public web sources - with a column log of every change and its evidence URL. How I will run it: 1) Ingest all source files into one staging table (Excel or Sheets - your choice for the working file). 2) Normalise phones/emails/addresses, trim whitespace, standardise case, then de-dupe on the strongest key available (email first, then phone+name). 3) Web-verify contacts via public sources only (company sites, directories, LinkedIn public pages). Anything I cannot confirm stays flagged, never invented. 4) Apply your style guide: column order, header style, conditional colour coding. 5) Deliver .xlsx + Google Sheets copy, plus a corrections log (old -> new, reason, URL). Honest constraint: web verification quality depends on how public the contacts are. Private individuals without a web footprint will be marked unverified rather than guessed. I do this class of work daily - data cleaning, spreadsheet pipelines, and verification logs. Happy to mirror your sample sheet on a free test slice before the full run. Bid Rs.14,000 / 5 days.

Hello, I can consolidate your customer files into one reliable master workbook, remove duplicates, standardize each field, and document every correction so the final dataset remains fully traceable. My professional background includes six years as a Data Analyst with the World Food Programme, where data quality, validation, reconciliation, and clear reporting were essential. I will first profile the source files and define matching rules for names, phone numbers, emails, and addresses. I will then merge the records, identify exact and probable duplicates, validate contact details against reliable public sources, and flag uncertain cases rather than guessing. You will receive the cleaned Excel workbook, an equivalent Google Sheets version, a column-by-column correction log with supporting URLs, validation checks for missing or conflicting values, and formatting aligned with your style guide. My bid is INR 22,000 with delivery within seven days after reviewing the file count, record volume, and sample format.
