Data Cleaning & Standardization for Accurate BI Reporting

Bad data breaks reporting, ruins imports, and forces teams into endless manual fixes. If your spreadsheets are filled with duplicates, mismatched formats, inconsistent fields, and unreliable values, your BI tools will never give you accurate numbers. My work focuses on building clean, stable, and scalable datasets that remove this chaos for good.
I analyze every column, correct malformed values, enforce formats, rebuild missing logic, validate data types, remove duplicates, and standardize structures across all files. You receive clean data, audit rules, error-flagging matrices, and import-ready outputs tailored for your BI or internal system.

This is not simple data entry it’s structured, rule-driven data processing designed to eliminate rework, prevent integration failures, and restore dependable reporting. The result: consistent data, fewer errors, smooth imports, and a reliable foundation your team can trust and scale on.

Action Plan:
1. Audit & Mapping
I review every column, detect inconsistencies, map field behavior, and identify rule gaps.
2. Rule-Based Cleanup
Apply strict cleaning logic: formatting fixes, type correction, malformed value repair.
3. Deduplication Process
Run multi-stage dedupe using unique keys, fuzzy match, and logic checks.
4. Validation & Error Flagging
Build validation layers, highlight conflicts, and generate an issue matrix.
5. Final Standardization
Deliver clean, consistent, import-ready data aligned with your system structure.

FAQ:
1. Can you handle large or messy datasets?
Yes. I work with large, multi-sheet, multi-source datasets using structured workflows.
2. Do you set up recurring cleanup processes?
Yes. I can build repeatable cleaning and validation workflows.
3. What formats do you support?
Excel, CSV, Sheets, system exports, and most structured text formats.
4. Will you match my system’s required structure?
Yes. I align all outputs with your BI tool, CRM, ERP, or custom system.
