I have several customer lists scattered across different Excel workbooks. My priority is to merge every record into a single, reliable master sheet so I can finally trust the data. Accuracy comes first: I need duplicates identified and resolved, inconsistent name or address fields standardised, and any obvious entry errors corrected. Once the data is clean, every email address must be verified online. Invalid or disposable addresses should be flagged or removed, and I would like a quick summary of how many contacts remain deliverable once you finish. Deliverables • A consolidated Excel file containing all unique, cleaned customer records • A brief reconciliation log showing where duplicates were merged or conflicts resolved • An email-verification report listing valid, invalid, and unverifiable addresses • (Optional but appreciated) a repeatable macro, Power Query script, or short step-by-step note so I can rerun the process later Feel free to lean on any combination of Excel formulas, Power Query, or VBA—whatever gets the job done accurately and efficiently. Data privacy is important, so all files must stay confidential and be deleted from your side once the project is complete. If you’ve tackled similar consolidation and email-verification tasks before, let me know your approach and estimated turnaround time.

I've consolidated scattered customer lists into clean master files before, and data hygiene is my daily work. My plan: - Merge every record from the workbooks into one master sheet, resolving duplicates explicitly (I'll log where and how each merge was decided). - Standardise inconsistent name and address fields and correct obvious entry errors, keeping a reconciliation log. - Verify every email address against deliverability checks, flag or remove invalid and disposable ones, and produce a report listing valid, invalid and unverifiable addresses plus how many contacts remain deliverable. - Build the repeatable path you asked for: I'll include a Power Query script (or macro) with a short note so you can rerun the consolidation and verification later. Deliverables: consolidated clean Excel, reconciliation log, email-verification report, and the repeatable script + instructions. Delivery in 4 days. How many total records and which fields are in play? With that I'll size the verification pass and confirm the deliverable layout.

Hi, I can consolidate your scattered customer workbooks into one reliable Excel master file while keeping the process transparent enough for you to see exactly what was merged, corrected, or flagged. I would handle the project in three controlled stages: Consolidation: combine all source workbooks into one consistent structure while preserving every valid customer record. Data cleaning: identify duplicates using name, email, phone, and address comparisons; standardize inconsistent fields; and flag conflicts instead of making unsupported assumptions. Email verification: check each address using an appropriate verification method, then classify it as valid, invalid/disposable, or unverifiable so the final deliverability count is clear. Before delivery, I’ll run a second QC pass to check record counts, duplicate resolutions, missing fields, and formatting consistency. You will receive: Clean consolidated Excel master file Unique customer records with standardized fields Duplicate/conflict reconciliation log Email verification report Final summary showing total, valid, invalid, and unverifiable contacts A simple repeatable workflow/Power Query setup where practical, so future files can be processed more efficiently Your customer data will be treated as confidential and retained only for the duration of the project.

Hi, this is a strong fit for my Excel/Python data-processing background. I can consolidate the workbooks into one clean master dataset, normalize inconsistent fields, identify and resolve duplicates, and provide a reconciliation log showing what was changed. For email validation, I can check formatting and domain/mail-server validity and clearly separate valid, invalid, and unverifiable addresses. If you require mailbox-level verification through a specific service, I can incorporate that as well once we confirm the preferred method. I can also provide a small repeatable Python utility or documented process so the consolidation/cleanup can be rerun on future customer lists rather than making this a one-time manual exercise. Before starting, I'd like to confirm approximately how many workbooks/records are involved and whether the files share similar column structures. Once I see that, I can confirm the turnaround. Thanks, Jack

Hello, I understand your priority is data accuracy first — a single reliable master sheet with duplicates properly resolved and names/addresses standardised, not just merged. My approach: 1) Consolidate all workbooks and de-duplicate using key-field matching (name/email/phone), flagging near-duplicates for manual review rather than auto-merging blindly. 2) Standardise formatting (case, address structure, phone/email formats). 3) Run each email through online verification checks (syntax, domain/MX validity, disposable-domain detection) and categorise as valid/invalid/unverifiable. 4) Deliver the clean master file, a reconciliation log of every merge/conflict decision, the verification report, and a short step-by-step note so you can rerun this yourself next time. All source files will be deleted on my end once you confirm delivery. I have 15+ years of Business Process Analyst/Accounts Payable experience, so accuracy and audit-trail documentation are second nature to me. Happy to share a sample of cleaned records early for your approval. Can deliver within 3 days.

Your priority on accuracy and having a reliable master customer sheet is exactly where I can help. I can consolidate the Excel workbooks into one structured master file, identify duplicates, standardize names and addresses, and clean obvious data inconsistencies. I have 5+ years of administrative experience and strong Excel skills, including data cleaning, processing, formatting, Power Query, PivotTables, and spreadsheet organization. I can also provide a clear reconciliation log so you can see how duplicates and conflicting records were handled. For the email verification stage, I want to be transparent: I can prepare and organize the email data for verification, but I would need to use a client-approved verification service or tool rather than claim experience with a specific online verifier I have not used. I’m available to start immediately and can provide a small sample first to demonstrate my approach before processing the full dataset. Best regards, Fajri Ardiansyah SPT P.S. Do you already have a preferred email verification service, or would you like me to work with the tool you provide?

I provide you with a cleaned-up customer record file, but also a reconciliation log documenting every step taken as well as an email-verification report indicating invalid or unverifiable addresses.

Hi — I can merge the workbooks into one auditable master sheet, resolve duplicates, standardize names and addresses, and correct obvious errors without silently discarding records. I’ll use Python/openpyxl plus Excel checks, retain source-row references, and provide a change log and QA summary. For email verification I can run syntax, domain/MX, disposable-provider, and duplicate checks; any address that cannot be confirmed safely will be flagged rather than guessed. My portfolio includes Excel/CSV cleanup and reusable validation pipelines. Delivery is 7 calendar days after receiving the files and agreeing the merge key, including one focused correction pass. Approximately how many workbooks and rows are there, and does “verified online” mean domain/MX validation or confirmed inbox deliverability through a service/API
