Customer Data Accuracy Validation

@Microlent

Hello! I can perform a thorough accuracy and validation pass on your customer records, ensuring emails, phone numbers, and postal addresses are verified, corrected where possible, and clearly flagged where issues remain. I’ll focus on precision, traceability, and a repeatable workflow you can reuse on future datasets. I’ll work directly with your Excel file and MySQL export, using a structured validation pipeline built with Python and supporting tools where helpful. Email formats and domains will be checked, phone numbers normalized and validated by region, and postal addresses verified and standardized where possible. Every correction or unresolved issue will be logged so nothing is changed silently. The process will be documented so you can rerun or extend it later. What you’ll get: • Cleaned dataset with validated email, phone, and postal fields • Separate error and correction log with clear explanations • Repeatable validation script or workflow outline • Excel and MySQL-ready outputs • Optional structure to extend later for deduplication or compliance checks Let’s open the chat. I can review the dataset size and regions involved, confirm validation rules, and give you a fast turnaround estimate before starting. Best regards, Jasmin

Hello, Hi, I’m interested to hear more about the project, and if you award me the work, I’d be pleased to discuss this further and get started as soon as possible. Based on your requirement, I propose a structured data-validation workflow aligned with the same FMCG-grade data practices we follow, where accuracy, repeatability, and auditability are critical. How I will approach this (Flow of Work): Review Excel and MySQL data structure and define validation rules Validate email formats and domains, flagging invalid or unreachable entries Normalize and validate phone numbers (country codes, length, format) Validate postal addresses using standard address rules and corrections where possible Log every correction, failure, or ambiguity in a clear error report Output a cleaned dataset in Excel and MySQL-ready formats The process will be built using repeatable tools such as Python scripts (or Power Query/OpenRefine if preferred), so you can rerun the same checks on future data drops without manual effort. The final delivery will include the cleaned dataset, a detailed issue log, and a brief explanation of the validation logic used. If you have sample files, validation rules, or reference standards you already follow, please send them—it will be better for understanding your data, feature alignment, and accurate estimation. I’m keen on clear communication and potential long-term collaboration. Let’s connect and discuss further. Best regards, Prakash.S

@reedsystems

Hi, Thank you for considering my proposal! Given your project details, I'll outline a plan to address the file accuracy check. Firstly, I will begin by importing both the Excel and MySQL export files into Python using pandas. This will allow me to perform validation checks on email addresses, phone numbers, and postal addresses in a structured manner. For email validation, I’ll use regex patterns; for phone numbers, I'll apply country-specific formats where applicable; and for postal addresses, I'll leverage OpenRefine for more accurate parsing. Once the data is cleaned, any unresolved issues will be logged along with proposed corrections. The final dataset will include validated fields, with a clear error log detailing each change or issue encountered. Additionally, I’ll provide documentation on the validation methods used, ensuring the process can be repeated in the future if needed. Regarding your interest in scalability, once this initial phase is complete, we can explore integrating duplicate detection algorithms and regulatory compliance checks using libraries like pandas for data manipulation and open-source tools for additional validations. I'm confident this approach will meet your needs efficiently. Please let me know if you have any questions or require further details. You can check the portfolio on my profile for references

@yuliussmayoru

Hello, datasets like this usually “look fine” until you hit hidden whitespace, bad country codes, and copy-pasted addresses, so I’ll run strict validation rules, normalize formats, and produce a clean file plus an audit log you can rerun anytime. • Import: load your Excel and MySQL export into one master table with consistent column names and a stable primary key so nothing shifts. • Email validation: trim/normalize, catch invalid syntax, disposable domains if you want, and flag risky patterns rather than guessing. • Phone validation: parse by country, enforce E.164 formatting, validate length and prefixes, and separate mobile vs landline where possible. • Address validation: standardize casing and components, flag incomplete addresses, and optionally verify via a geocoding/postal API if you approve. • Output: cleaned dataset plus an error log showing original value, corrected value, rule triggered, and whether the fix is confident or needs manual review. • Repeatable workflow: I’ll deliver a Python script or notebook (or Power Query steps) so you can rerun the exact same checks on future exports. If you want duplicates and compliance later, I’ll structure it to add fuzzy matching and rule packs without rewriting the pipeline. Warm regards, Yulius Mayoru

@maksymh31

Hello, I will validate and clean your Excel and MySQL customer records by verifying every email, phone, and postal address with repeatable scripts and processes. My approach: use Python (pandas + regex), libphonenumber for phones, SMTP/domain checks for emails, and libpostal or API lookups for addresses; supplement with Power Query/OpenRefine steps for quick manual fixes. I will flag invalid entries, attempt automated corrections (formatting, common-domain fixes, standardization), and produce a cleaned Excel/MySQL-ready file, a detailed error log of corrections/unresolved items, and a concise README with the validation script and rerun steps. To start I need a sample export (≈500 rows), list of countries to validate, and any business rules. Timeline: initial pass in 3 days, full delivery after review. Can you share a sample export (around 500 rows) and confirm which countries/formats I should prioritize for address and phone validation? Best regards, MAKSYM
